FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with anhedonia is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about anhedonia, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to anhedonia, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on anhedonia. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to anhedonia, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser.

CHAPTER 1. STUDIES ON ANHEDONIA Overview In this chapter, we will show you how to locate peer-reviewed references and studies on anhedonia.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and anhedonia, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “anhedonia” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Erectile Dysfunction: The Role of Concomitant Diseases Source: Physician Assistant. 24(6 Supplement): 12-16. June 2000. Contact: Available from Springhouse Corporation. Physician Assistant Journal, 1111 Bethlehem Pike, P.O. Box 908, Springhouse, PA 19477-0908. (215) 628-7758 or (800) 7834903. Website: www.pajournal.com. Summary: An estimated 20 to 30 million men and their partners are affected by erectile dysfunction (ED). However, patients and health care providers can often be uncomfortable discussing the subject. Understanding the causes of ED, which can range from alterations in the hemodynamics of penile blood flow to hormonal imbalances, can be helpful in dispelling the embarrassment and discomfort surrounding this disorder. Written for physician assistants, this article reviews the causes and concomitant diseases

Anhedonia
associated with ED, as well as the importance of early recognition and patient education. Hypertension (high blood pressure), arteriosclerosis (deposits of plaque in the arteries, causing 'hardening'), and lipid disorders are frequently associated with ED. Diabetes can affect the microvasculature (small blood vessels) of the nerves that regulate blood flow to and from the penis. Medications used to treat common diseases such as hypertension, cardiovascular disorders, and depression can precipitate ED, as can medications used for decongestion and appetite suppression. The causes of ED are categorized in three groups: organic, psychogenic, and mixed (organic and psychogenic). Psychogenic causes of ED include depression, anxiety, stress related disorders, religious orthodoxy, obsessive compulsive disorder, anhedonia, sexual phobias, and sexual deviance. The author stresses that if the clinician can identify an erectile problem early, psychosocial sequelae such as embarrassment, anxiety, self doubt, depression, withdrawal from relationships, divorce, or other problems may be averted. One table lists common drugs that can affect erectile function; another table reprints a five item sexual health inventory for men. 3 tables. 10 references. •
Clinical Features in Depression in Old Age: A Case for Minor Depression Source: Current Opinion in Psychiatry. 4(4): 596-599. August 1991. Summary: This journal article reviews research indicating that minor depression may be an important clinical entity for resolving many of the epidemiologic and diagnostic dilemmas confronting clinical investigators of depression in late life. The first part discusses the epidemiologic dilemma presented by discrepancies between the increased burden of depressive symptoms identified in elderly populations and the relatively low prevalence of depressive disorders found in community studies of the elderly. The second section presents phenomenologic data on minor depression that may account for these discrepancies. These data suggest that minor depression is not a single entity but may include many syndromes, including those described by various authors as persistent anhedonia, recurrent depressive disorders, and chronic minor depressive disorder associated with cognitive impairment and dementia. The third section reviews findings on the pharmacologic treatment of minor depression. 19 references.
Federally Funded Research on Anhedonia The U.S. Government supports a variety of research studies relating to anhedonia. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to anhedonia. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use 2 Healthcare projects are funded by the National Institutes of Health (NIH), Substance Abuse and Mental Health Services (SAMHSA), Health Resources and Services Administration (HRSA), Food and Drug Administration (FDA), Centers for Disease Control and Prevention (CDCP), Agency for Healthcare Research and Quality (AHRQ), and Office of Assistant Secretary of Health (OASH).

Project Title: DEPRESSION
AMYGDALOSTRIATAL
CIRCUIT--AFFECTIVE
BEHAVIOR--
Principal Investigator & Institution: Taylor, Jane R.; Associate Professor; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2002; Project Start 16-JUL-2002; Project End 30-JUN-2006 Summary: Neurobiological studies of major depression have identified dysfunctional cognitive-affective-motor regions; however, the details of these altered physiological and structural changes, and the molecular basis for these alterations, remain to be elucidated. Recent imaging data suggest that depressed patients have increased blood flow/metabolism in the amygdala concomitant with decreased blood flow and volume in orbitofrontal cortex and ventromedial striatum. These effects may be relevant to the psychopathology of depression because cortico-limbic - striatal dysfunction may contribute to hypersensitive stress, fea4r, and anxiety responses, anhedonia, affective alterations, and changes in cognitive function. Thus, it is critical to understand the molecular basis of neuroplasticity in these brain regions implicated in depression and mood disorders and the resulting cellular and behavioral correlates. This project will thus focus on the role for the extended amygdala (notably the central nucleus of the amygdala, and nucleus accumbens shell) in depression and alterations in PKA/CREB signaling in these regions because the involvement of PKA/CREB in learning/plasticity is well established and because antidepressant treatment increases PKA/CREB activity. Specifically the functional and molecular correlates of plasticity in response to stress and antidepressant treatment will be investigated. We hypothesize that alterations in the extended amygdala results in abnormal processing of affective/emotional stimuli and behavioral regulation by appetitive and aversive events. Combined with alterations of neural signaling within the ventral striatum that contribute to anhedonia, negative stimuli may also exert heightened suppressive consequences on behavior in depression. In addition, sustained increases PKA/CREB produced by anti-depressants would be predicted modify behavior by enhancing plasticity associated with learning and affective processes. Using direct pharmacological manipulations, transgenic murine models, vector-mediated over-expression of CREB and stress-induced animal models of depression, we will investigate the role of PKA/CREB signaling within the extended amygdala in reactivity to unconditioned aversive stimuli and/or anhedonia (sensitivity to appetitive rewards), and appropriate control procedures, as well as the mechanism of action of anti-depressant drugs in order to evaluate and validate the relevance of these processes to models of depression.

Project Title: CORE--LABORATORY ANIMAL AND ASSAY Principal Investigator & Institution: Knight, David L.; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2003; Project Start 11-AUG-2003; Project End 30-JUN-2008 Summary: The Animal/Assay Core of the Emory-GSK-NIMH Collaborative Mood Disorders Initiative represents an integral component of the overall Center. The Animal/Assay core will serve as the source of all rodents used by the individual preclinicat Research Projects. Specifically, this core will produce and characterize a rat epigenetic early life stress (ELS) model associated with vulnerability to the development

Anhedonia
of a depression-like syndrome. We will also continue the breeding and genetic selection of the "Swim-test Susceptible" (Susceptible) as well as the "Hyperactive" (Hyperactive) rat line. The efficacy of various novel antidepressant treatments in reversing aspects of a depressive-like syndrome of these rat models will be tested. To this end, this core will characterize the behavioral and HPA axis stress responsiveness of animals, provide phenotypic screening for anhedonia, anxiety-/fear-like behavior, resident intruder social defeat exposure, and provide surgical services such as chronic jugular catheterization, CNS guide cannula implantation, Alzet minipump preparation and implantation, and other protocols as required by the Research Projects. The core will provide characterized rats or will provide brain tissue, other tissue (adrenal, pituitary, etc), blood, or CSF from the various rat models to the individual Research Projects. This organization has the advantage of maintaining consistency in animal handling and implementation of all protocols so that each preclinical Research Project receives identically characterized and treated animals for study. This Core will also provide a common set of state-of-the-art biochemical analyses to Center researchers. The assay laboratories of the Core will provide assessments of hypothalamic-pituitary-adrenal (HPA) axis function, CRF and CRF mRNA expression, neurotransmitter (central and peripheral) levels, and antidepressant concentrations to the individual Research Projects of the Center. Accurate measurement of these parameters is important to characterize each of the preclinical and clinical model systems of depression and the effects of the novel antidepressants on the neurobiological consequences being investigated by the Center. Having these determinations performed by a central facility using a common set of assay modalities will provide the opportunity to compare models across strain and species while eliminating variability from having assays performed at different sites. Additionally, having a Core devoted to these analyses will guarantee high quality assay execution, allow for economies-of-scale in the purchase of assay reagents and technician time, and enable Center investigators to more fully concentrate their efforts on the unique aspects of their particular project.

Project Title: CORE--PSYCHOPHARMACOLOGY/BIOMEDICAL RESEARCH Principal Investigator & Institution: Katz, Ira R.; Professor; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002 Summary: The Laboratory for Psychopharmacological/Biomedical Research has been a key component of the CRC since its inception in 1986. Significant findings have include the demonstration that treatment of depression with standard tricyclic agents remains efficacious even in the oldest and most frail of patients, that those depressions associated with "failure to thrive" and dementia differ in treatment response from other disorders and that medications commonly used for treatment of medical disorders in late life can cause psychiatric symptoms. It provides an ongoing infrastructure to enable pharmacological and biomedical research through the conduct of its own intrinsic research, facilitating collaborative research with CRC scientists and others, and outreach/consultative activities with a wide array of investigators and trainees. It also actively participates in multi-center clinical trials of the treatment of the mental disorders of late life, and works to develop these studies. This application requests support for the Laboratory to continue to provide an enabling infrastructure for this line of investigation. It also requests support for three specific pilot investigations: 1) A double-blind, placebo- controlled, randomized clinical trial of venlafaxine for the treatment of depression and pain associated with osteoarthritis. This is an intervention

development study designed to provide information on the value of pharmacological treatment for the most common disabling condition in late life and to advance our understanding of the treatment-relevant interactions between depression and pain. 2) A study of the prevalence of subcortical and deep white matter hyperintensities, and of their association with cognitive (e.g., executive function) deficits and anhedonia or apathy (non-depressed) patients with diabetes. This study is designed to determine whether patients at high risk for "subclinical cerebrovascular disease" exhibit psychiatric symptoms that may targets for (primary or secondary) preventative interventions. 3) Exploratory studies of the behavioral pharmacology of the inflammatory cytokines. These will include challenge studies in healthy young adult volunteers of the subjective, behavioral and physiological responses to typhoid vaccine, and treatment studies in frail elderly patients of Tumor Necrosis Facto antagonists. The research is designed to develop models for the treatment of cytokine-mediated sickness behavior and depression. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CORE--RAT Principal Investigator & Institution: Plotsky, Paul M.; Glaxosmithkline Professor; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2002 Summary: The Rat Model Core (Core B) of the Emory University Silvio O. Conte Center~f6r the Neuroscience of Mental Disorders (CCNMD) represents an integral component of the overall Center. Core B will serve as the source of all rodents used by the individual preclinical Research Projects. In specific, Core B will produce and characterize a rat epigenetic early life stress (ELS) model associated with vulnerability to the development of a depression-like syndrome. Core B personnel will breed rodents, provide high quality animal care and uniformly applied neonatal manipulation protocols necessary to generate the ELS model, characterize the phenotype of all animals, ascertain the stage of the estrus cycle in adult female animals, and provide experimental manipulations as required by individual preclinical Research Projects within the Center. This epigenetic ELS model consists of Long Evans rats which are exposed to different rearing conditions from postnatal days (PND) 2-14, including: (1) animal facility reared (AFR) colony controls, (2) brief handling plus 15 min maternal separation (HMS 15) handling controls, (3) brief handling plus 180 min maternal separation (HMS 180). All individual Research projects will assess these animals for gender specific effects. Comparison of data obtained from these standardized rearing conditions among the various basic Research projects of this CCNMD will permit identification of central neurocircuit and intracellular mechanisms which are impacted by early life stress and which give rise to depressive-like syndrome; furthermore, since the animal models will be standardized, regression modeling can be used to elucidate interactions among these CNS systems in the genesis of this condition. Furthermore, the efficacy of various treatments (antidepressant, antisense, corticotropin releasing factor antagonist) in reversing aspects of depressive-like syndrome will be tested in these models. To this end, Core B will characterize the behavioral and HPA axis stress responsiveness of each animal, provide phenotypic screening for anhedonia, anxiety4fear-like behavior, as well as pr6viding surgical services such as chronic jugular catheterization, CNS guide cannula implantation, Alzet minipump preparation and implantation, resident intruder social defeat exposure, and other protocols as required by the Research Projects. Core B will provide characterized rats or will provide brain tissue, other tissue (adrenal, pituitary, etc), blood, or CSF from the HMS rats to the

Project Title: DEPRESSION AND CARDIOVASCULAR PATHOLOGY
HEART
FAILURE
ASSOCIATED
Principal Investigator & Institution: Johnson, Alan K.; Associate Professor; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2003; Project Start 21-JAN-2003; Project End 31-DEC-2007 Summary: Depression is both a debilitating psychological disorder and a condition that affects an individual's physical well-being. Depression is a recognized risk factor for heart disease. Research has demonstrated that depression predisposes an individual to myocardial infarction, sudden death, atherosclerosis, thrombosis and arrhythmias. While the behavioral and cognitive aspects of depression have been studied extensively, there has been much less research investigating the mechanisms responsible for the physiological consequences of mood disorders. Exposure of rodents to a series of chronic mild stressors (CMS) generates key behavioral characteristics of human depression that are observable and quantifiable. The CMS model of experimentallyinduced depression (ID) mimics the reduced responsiveness to pleasurable stimuli (anhedonia)which is a pivotal diagnostic criterion seen in depression. In the CMSdD model, anhedonia is induced by presenting mild unpredictable stressors (e.g., paired housing, stroboscopic illumination, white noise) of varying durations. In rats,anhedonia is operationally defined as a decrease in responding for a previously demonstrated reinforcer (reward). Recently, we have begun to characterize cardiovascular function in rats with CMS-ID. We have found that rats exposed to CMS for 4 weeks showed anhedonia along with cardiovascular alterations. Similar to patients with depression and with heart failure,CMSgD rats had elevated resting heart rates and reduced heart rate variability. In addition, rats exposed to CMS have increased susceptibility to experimentally-induced premature ventricular contractions. In other studies investigating the behavioral consequences of heart failure, we have found evidence of anhedonia (i.e., experimental depression) in rats with experimental myocardial infarction. The proposed research program will extend our characterization of the cardiovascular changes that accompany experimentally-induced depression and investigate the role of brain serotonergic mechanisms that are hypothesized to be common in the mediation of cardiovascular alterations that accompany both experimental depression and experimental heart failure.

Project Title: DO PLEASURE DEFICIENCIES FOSTER SMOKING? Principal Investigator & Institution: Werth, Jessica M.; Psychology; University of Illinois at Chicago 1737 West Polk Street Chicago, Il 60612 Timing: Fiscal Year 2002; Project Start 11-APR-2002 Summary: The proposed research will investigate the hypothesis that smoking enables trait-anhedonic people to experience pleasure in situations that commonly invoke positive moods among those without trait-anhedonia. This premise will be tested by evaluating changes in positive moods in trait-anhedonic people vs. non trait-anhedonic people after exposure to the following conditions: a positive mood induction while

smoking, a positive mood induction while not smoking, and a neutral mood induction while smoking. It is hypothesized that trait-anhedonic people will only be responsive to a positive mood induction if they are allowed to smoke. In other words, it is expected that trait-anhedonic smokers will require the pharmacologic effect of nicotine in combination with a pleasurable psychological stimulus to experience a degree of positive mood elevation that nonanhedonics experience without smoking. Positive mood will be measured via self-report. This study will be the first to examine the effect of smoking on a trait-anhedonic person's ability to experience pleasure. Results will enhance understanding of mechanisms that promote smoking among those with pleasure deficits, and may contribute to the development of smoking cessation treatments and other substance control interventions for people with chronic difficulties experiencing pleasure.

Project Title: DOPAMINERGIC AND NORADRENERGIC SYSTEMS Principal Investigator & Institution: Kuhar, Michael J.; Candler Professor of Pharmacology; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2002 Summary: Early life stressors~have profound and lasting impact on behavior and neuroendocrine function. Indeed, clinical epidemiological studies have shown that childhood abuse and/or neglect is a significant risk factor for the development of adult psychopathology. These effects are due to changes in brain morphology and neurocircuit function that are only partially documented. Clarification of these changes could lead to new treatment strategies to ameliorate the deficiencies caused by the early life stress or by genetic factors. It has been known for many decades now that CNS catecholaminergic systems play a major role in the regulation of behavior. Depression has long been linked to dysfunction of dopaminergic and/or noradrenergic systems in the brain. This is not surprising as dopaminergic and noradrenergic systems have been linked to reward/motivation and to vigilance, respectively. These circuits also participate in regulation of the hypothalamic-pituitary-adrenal (HPA) axis. Clinical depression as well as many animal models of depression-like syndrome are characterized by aberrant vigilance expressed as anxiety, anhedonia, and dysregulation of the HPA axis. The current project will focus on a comparison Of the development and function of these important neural systems in an epigenetic (early life stress) model of depression-like syndrome in rodents. Additionally, a limited number of studies will be performed on a early liter stress nonhuman primate model. Neurochemical, molecular, behavioral, and electrophysiological approaches will be used to characterize these neural systems in these animal models throughout neonatal development and maturity under basal, stress (acute and chronic) conditions, and in response to antidepressant treatment. Both males and females will be used. We hypothesize that alterations in the development and/or function of dopaminergic and/'or noradrenergic neural systems underlie the altered mood, reward, reinforcement, and motor function in these animal models. Further, we postulate that catecholaminergic neurocircuits may become "sensitized" by early life stress leading to enhanced vulnerability to the effects of later exposure to adverse life events thus increasing their risk of developing major depression or related mood disorders. Multiple interactions with other preclinical and clinical components of the Emory University Center for the Neuroscience of Mental Disease will benefit these studies both in terms of the uniformity of the animal models and their treatment but also in terms of intellectual cross-fertilization.

IN
IFNA-INDUCED
Principal Investigator & Institution: Miller, Andrew H.; Professor; Psychiatry and Behavioral Scis; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2004; Project Start 01-DEC-2003; Project End 30-NOV-2008 Summary: (provided by applicant): Depression in the medically ill is a significant public health concern, occurring in up to 50% of patients and having a significant impact on treatment adherence, quality of life, and morbidity and mortality. New developments in the conceptualization of depression in the medically ill have focused on the potential role of immune activation/inflammation and the associated release of proinflammatory cytokines. Proinflammatory cytokines have been found to influence neurobiologic function including neurochemistry and behavior, and induce a depressive syndrome that has overlapping features with major depression. The long term objective of the proposed work is to further understand the neural correlates of this cytokine-induced depression as it relates to depression in the medically ill. As a model system, we plan to study patients receiving the cytokine, interferon (IFN) alpha, for the treatment of hepatitis C. IFN alpha is a potent inducer of proinflammatory cytokines (especially interleukin 6) and leads to depressive symptoms in 30-50% of patients depending on the dose. Preliminary data from our lab indicate that IFN alpha treatment is associated with reduced evoked activity in the striatum and medial prefrontal cortex as determined by functional magnetic resonance imaging (fMRI). These findings, in conjunction with clinical evidence of impaired functioning of the basal ganglia (e.g. reduced reaction time, psychomotor slowing, akathesia and anhedonia) in IFN alpha-treated patients, suggest that dysfunction of fronto-striatal neurocircuitry may underlie IFN alphainduced depressive symptoms and may represent a critical pathway by which cytokines induce depression. The fundamental hypothesis of the proposed work is that IFN alphainduced depression begins with reduced activation of striatal neurons that is associated with psychomotor slowing and anhedonia and in turn contributes to reduced activity in the prefrontal cortex. Reduced activity in the prefrontal cortex is then associated with the development of depressive symptoms and cognitive dysfunction. Thus, we hypothesize that reduced evoked activity in the striatum will 1) be predictive of the development of depressive symptoms during IFN alpha therapy, 2) will precede the development of reduced activity in the prefrontal cortex, and 3) will be a predominent feature of IFN alpha-induced depression compared to depression in medically healthy individuals. To test these hypotheses, we plan to conduct fMRIs and neuropsychiatric assessments in 40 patients with hepatitis C at various time points during IFN alpha therapy. Results will be compared to control populations of hepatitis C patients awaiting IFN alpha treatment (N=20) and medically healthy subjects with and without major depression (N=20 per group). Results from these studies will provide important new data on neural pathways by which cytokines induce depression and will establish a foundation for developing novel strategies to diagnose and treat depression in the medically ill.

Summary: (provided by applicant): Dysregulation of the hypothalamic-pituitaryadrenal axis (HPA), which controls the endocrine stress response, has been implicated in the pathogenesis of stress-related disorders including depression and anxiety. It is believed that at least part of the dysfunction is related to a lack of glucocorticoidmediated negative feedback to the hypothalamus. It has been hypothesized that glucocorticoid receptors (GRs) within the hippocampus (HPC) are important mediators of this inhibition. In order to investigate this hypothesis we will take advantage of recent advances in transgenic technology. We have generated mice with a conditional knockout of the GR in area CA1 of the HPC. In addition, we are in the process of generating mice with inducible expression of GRs in the HPC. Analysis of these two lines of mice will allow us to discretely address the role of GRs within the HPC in regulation of the HPA axis. We will examine these mice for changes in basal and/or stress-induced activation of the HPA axis. These mice will also be analyzed for changes in stress/depression related behaviors. Decreased hippocampal GR has been associated with a number of animal models of depression, while increased hippocampal GR is correlated with a decreased susceptibility to depression. We will therefore examine how changes in GR expression in the HPC influence depression related behaviors including anxiety, despair, anhedonia, and learning. We will further examine whether these mutations influence susceptibility to two established models of depression: chronic mild stress and social defeat.

Project Title: INFORMATION-PROCESSING BIASES IN DEPRESSION Principal Investigator & Institution: Gotlib, Ian H.; Professor; Psychology; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2004; Project Start 01-JAN-1999; Project End 31-DEC-2006 Summary: (provided by applicant): Depression is among the most prevalent of all psychiatric disorders, accounting for over 20% of economic costs for all mental illness. An important public health priority is the development of methods for identifying factors that both increase individuals' vulnerability to depression and hinder recovery from this disorder. Pursuing this objective, we have been conducting research that broadens the focus of cognitive models of depression by examining patterns of biological reactivity to emotional stimuli. Extrapolating from our earlier studies and from existing models, we predicted that individuals diagnosed with Major Depressive Disorder (MDD) would exhibit increased autonomic arousal and neural activation in response to negative stimuli. But our findings indicated otherwise; in both fMRI and psychophysiological studies, MDD individuals demonstrated less activation and arousal in response to both positive and negative stimuli than did nondepressed controls. Moreover, greater activation and reactivity predicted improved functioning over the following year, independent of MDD severity. In reconciling and integrating these results with our earlier findings, we are broadening and refining cognitive theories of depression to include a consideration of affective chronometry, sensitivity to reward stimuli, and biological functioning, not only to describe the functioning of depressed individuals, but also to predict recovery from this disorder. The studies proposed in this application are designed to test a more comprehensive formulation of depression and to systematically rule out important alternative explanations for our obtained results. Based on our initial findings, we posit that when confronted with an emotionallyvalenced stimulus, depressed persons immediately attend to it; if the stimulus persists, they shut down their processing and disengage from it. Moreover, those depressed individuals who are able to stay engaged with emotional stimuli are likely to recover

from depression most quickly. The overall objective of this proposed project is to advance our understanding of the cognitive and neurobiological responses in MDD to emotional stimuli. We are particularly interested in the effects of stimulus type (i.e., affective valence), stimulus duration (i.e., affective chronometry), and the potential effects of specific patient characteristics (e.g., anhedonia, comorbid Axis-II personality disorder) on emotional functioning in depression. We propose to examine informationprocessing biases and reward responsivity, as well as concomitant neural activation and psychophysiological arousal, in response to emotional stimuli in depressed and nondepressed participants. Findings from the proposed studies testing these formulations will contribute importantly to the development of an integrative psychobiological theory of depression.

Project Title: LIMBIC DOPAMINERGIC SYSTEM IN MAJOR DEPRESSION Principal Investigator & Institution: Ordway, Gregory A.; Associate Professor; Psychiatry and Human Behavior; University of Mississippi Medical Center 2500 N State St Jackson, Ms 39216 Timing: Fiscal Year 2002; Project Start 14-DEC-2001; Project End 30-NOV-2005 Summary: A vast amount of research reveals that central dopamine (DA) containing systems are neuronal substrates of a broad spectrum of behaviors related to rewardseeking, motivation, and environmental responsivity. Disruption of these behaviors leads to anhedonia, social isolation, and psychomotor retardation that form core symptoms of depression. While there is little debate for a critical role of limbic structures, e.g. amygdala, in the regulation of mood and affect, the role of limbic DA in the pathobiology of depressive illness is not known. Functional imaging studies report involvement of limbic structures in depression, but few have focused on dopaminergic indices. Furthermore, there is a paucity of neurochemical studies of depression that have utilized postmortem brain tissue. Studies using postmortem brain tissue offer much higher anatomical resolution than it is offered by functional imaging. In preliminary studies, we have found lower dopamine transporter (DAT) and up-regulation of D2 receptors in the basal and central nuclei of the amygdala, but not in the other nuclei of this complex region, in major depression as compared to psychiatrically normal controls. These and other findings compel us to examine the possibility that there is diminished DA neurotransmission in subjects diagnosed with major depression (who died of suicide or natural causes). The central hypothesis of this proposal is that subjects with major depression have diminished mesolimbic DA activity that can be revealed by neurochemical abnormalities in discrete regions of the mesolimbic dopaminergic system. These neurochemical measures will be performed in discrete regions of the amygdala, (Aim 1), in the nucleus accumbens (Aim 2), and in the ventral tegmental area (VTA, Aim 3), core limbic regions of the brain. We also hypothesize that a distinct constellation of neurochemical abnormalities within limbic structures is specific for major depression (Aim 4), and will differentiate the pathobiology of major depression from that of suicide or schizophrenia. Groups of subjects to be studied will be: a) subjects with major depression who committed suicide, b) subjects with major depression not dying by suicide, c) sudden death non-psychiatric controls, and d) schizophrenics not dying by suicide. The proposed research will be the first focused investigation of potential abnormalities of limbic DA in major depression utilizing psychiatrically characterized subjects. The research will establish the specificity of neurochemical findings with respect to major depression and with respect to regional brain anatomy.

Project Title: MECHANISMS OF DEPRESSION AND CARDIOVASCULAR PATHOLOGY Principal Investigator & Institution: Grippo, Angela J.; Psychology; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2002; Project Start 01-APR-2002 Summary: (provided by applicant): This research proposal addresses physiological mechanisms and processes underlying the association between depression and cardiovascular disease. Human studies demonstrate a strong link between depression and coronary artery disease but have not progressed beyond correlational methods. The current proposal will examine the underlying mechanisms in depression and cardiovascular pathology by using a rodent model of depression (chronic mild stress) and a combination of behavioral, physiological, and pharmacological techniques. Rats will be exposed to chronic mild stress to induce the depression-associated sign of anhedonia (a reduced capacity to experience pleasure), and tested for cardiovascular impairments (Aim 1). Autonomic nervous system imbalance will be examined as a mechanism for the cardiovascular dysfunction (e.g., elevated heart rate and reduced heart rate variability) associated with the chronic mild stress model (Aim 2). In addition, central serotonin activity will be examined as a common pathophysiological factor underlying both depression and cardiovascular/autonomic dysfunction (Aim 3). This research will extend our knowledge of the interactions between psychological and physiological conditions, and possibly prompt the development of new treatments for patients with depression and/or cardiovascular disease.

Project Title: NEUROBEHAVIORAL PHARMACOLOGY OF STIMULANTS Principal Investigator & Institution: Cunningham, Kathryn; Associate Professor; Pharmacology and Toxicology; University of Texas Medical Br Galveston 301 University Blvd Galveston, Tx 77555 Timing: Fiscal Year 2002; Project Start 01-MAY-1990; Project End 31-MAY-2005 Summary: (Adapted from the Investigator's Abstract) Illicit cocaine use continues to be a pervasive problem in the United States; the State of Texas cites cocaine abuse as its greatest illicit drug threat. Cocaine intoxication, dependence and withdrawal are marked by psychological (e.g., euphoria, depression, anxiety, anhedonia, craving) and physiological symptoms (e.g., fatigue, hyperphagia, anergia). An elucidation of the neural mechanisms that underlie the in vivo effects of cocaine is required in order to design effective psycho- and pharmacotherapeutic approaches to the treatment of cocaine addicts. The behavioral effects of cocaine are critically dependent upon mesocorticolimbic circuits, particularly the pathway that originates in dopamine (DA) cell bodies in the ventral tegmental area and terminates in the nucleus accumbens. Serotonin (5-hydroxytryptamine, 5-HT) is involved in the etiology of psychotic (e.g., schizophrenia), affective (e.g., anxiety, depression) and somatic disorders (e.g., obesity). The innervation and localization of 5-HT1B, 5-HT2C or 5-HT4 receptors in mesocorticolimbic circuits and the ability of cocaine to inhibit 5-HT reuptake suggest that 5-HT contributes to the in vivo effects of cocaine. The current literature and our preliminary data support differential roles of each receptor in modulating spontaneous
14
Anhedonia
and cocaine-stimulated behavior. In the present proposal, the role of 5-HT1B (Aim 1), 5HT2C (Aim 2) and 5-HT4 receptors (Aim 3) in the locomotor stimulant and discriminative stimulus effects of cocaine will be investigated using novel ligands and receptor knockdown techniques. The pattern of immediate early gene expression in the presence vs. absence of receptor-specific ligands will be employed to localize the site of action of each receptor. Based upon these maps, microinfusions of 5-HT1B, 5-HT2C or 5HT4 receptor ligands or antisense oligonucleotides will be targeted to identified mesocorticolimbic nuclei in order to clarify the site of action for each receptor in spontaneous and cocaine-evoked behaviors. Modifications in 5-HT1B, 5-HT2C and 5HT4 receptors during withdrawal will also be established via analysis of behavior and levels of receptor mRNA and protein expression in brain at several time-points following termination of intermittent cocaine exposure. The experiments outlined will yield significant information concerning the interplay between 5-HT receptors and cocaine, elucidate the manner in with 5-HT controls DA in vivo and help to define the specific and unique roles of these receptors in behavior. As a consequence, new insight into the potential therapeutic strategies for cocaine dependence and a number of psychiatric disorders dependent upon normal 5-HT function will be gained.

Project Title: NEUROIMAGING STUDIES OF REWARD PROCESSING IN DEPRESSION Principal Investigator & Institution: Pizzagalli, Diego A.; Assistant Professor; Psychology; Harvard University Holyoke Center 727 Cambridge, Ma 02138 Timing: Fiscal Year 2004; Project Start 07-JUN-2004; Project End 30-APR-2009 Summary: (provided by applicant): The aim of this proposal is to investigate the functional neuroanatomy of depression. A promising strategy for parsing the heterogeneity of Major Depressive Disorder (MDD) is to identify phenotypes characterized by reliable functional brain abnormalities. Anhedonia, the lack of reactivity to pleasurable stimuli, is considered a trait marker for depression. Preclinical work suggests links among phenomena associated with depression - decreased hedonic responsiveness, exaggerated stress responsiveness, and dysfunction in the dopaminergic mesolimbic system - but in humans the neural underpinnings are largely unknown. Using behavioral, event-related potential (ERP), and functional magnetic resonance imaging (fMRI) techniques, this proposal aims to investigate these processes. A monetarily reinforced button-press task will be used to dissociate the neural circuitry involved in anticipation of and reactivity to reward or punishment. Experiment 1 addresses the spatio-temporal dynamics of brain mechanisms underlying anticipation of and reactivity to reward and punishment in subjects differing on objective measures of anhedonia, operationalized as decreased responsiveness to reward-related cues in a separate signal-detection task. Compared to controls, subjects with impaired reward responsiveness (n=20) are predicted to show lower activation in regions subserving reward processing (e.g., nucleus accumbens, medial prefrontal cortex) to rewardrelated, but not to punishment-related, cues. In the ERP data, decreased late frontal negativity wave to reward cues, and decreased medial-frontal negativity and P3 to reward feedbacks, are hypothesized. Experiment 2 extends this paradigm to subjects with a DSM-IV diagnosis of MDD. These subjects (n=23) are expected to show lower activation in regions subserving reward processing than controls (n=23) in response to reward-related cues, and higher activation in regions subserving processing of withdrawal-related cues. In the ERP data, medial-frontal negativity and P3 are predicted to differentiate the subject groups. Experiment 3 addresses the effects of mental stress on

15
reward processing in MDD. Compared to controls (n=21), depressed subjects (n=21) are expected to show a larger stress-induced reduction of activation in regions subserving reward processing, and a larger activation in regions subserving punishment processing. Decreased gray matter density in medial and subgenual prefrontal regions, as assessed by voxel-based MRI morphometrical analyses, is expected to be associated with the detrimental effect of stress on reward responsiveness. Overall, the integration of techniques with high temporal (ERP) and spatial (fMRI) resolution will enhance understanding of the functional neuroanatomy of depression.

Project Title: NICOTINE: COGNITION-AFFECT INTERACTIONS Principal Investigator & Institution: Gilbert, David G.; Professor; Psychology; Southern Illinois University Carbondale 900 S. Normal Carbondale, Il 629014709 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2006 Summary: (provided by applicant): The primary objective of this revised proposal is to characterize more fully when, how, and in whom nicotine modulates affect and attention to emotional stimuli. It is hypothesized that nicotine attenuates attentional bias to negative emotional stimuli and associative processing of such stimuli, thereby decreasing negative emotional states. This attenuation of negative attentional bias and associative processing by nicotine is hypothesized to result from nicotine's enhancing attentional and associative bias to positive and neutral stimuli that in turn compete with and inhibit negative affect-related processing. Nicotine-induced attentional and associative biasing is hypothesized to occur most strongly in situations where the frequency of negative stimuli is moderate or low and the subject has a significant degree of freedom of attentional choice. Thus, the effects of attentional choice (two-picture viewing) versus no-choice (one picture viewing) conditions on nicotine's ability to reduce negative affect will be assessed by presenting blocks with a series of 64 single or dual pictures on a computer. Mood will be assessed before and after each picture series block. The frequency of negative pictures in these series will be manipulated (either 16 [low frequency] or 48 [high frequency]). In the no-choice task, single pictures will be presented centrally on the computer screen. In the two-choice task, dual picture images will be presented simultaneously in the left and right visual field. Picture series blocks (64 single or dual pictures) will consist of the following 4.5 sec. sequence: the word "blink", a fixation cross, and a picture (or dual picture). In the two-choice condition, subjects will be instructed to allocate as much or little of their gaze time to a given picture, but to always be gazing at one of two pictures. In the no-choice condition, subjects will be required to maintain a 3 sec. gaze at each picture. Neutral or positive pictures will be interspersed in both the two-choice and no-choice tasks. Eye-gaze patterns during the two-choice task and no-choice task will be obtained with an infrared, computerized tracking system. In the two-choice task, maximal dysphoriareducing effects of nicotine are predicted to occur during blocks with a high frequency of negative pictures. Nicotine is predicted to reduce gaze directed toward negative pictures and to enhance attention to positive pictures. In the no-choice task, nicotine is expected to have maximal dysphoria-reducing effects when a low frequency of negative pictures is combined with intervening positive pictures. Potential moderating influences of gender, smoker-nonsmoker status, and individual differences in trait anxiety, depression, and anhedonia will be assessed with regression analyses. This work will use new experimental procedures and technologies, including the precise assessment to individual differences in continuously monitored eye-gaze patterns with an infrared, computerized tracking system. The new knowledge derived from these studies will be

Project Title: PROCESS OF CHANGE IN DRUG ABUSE BY SCHIZOPHRENICS Principal Investigator & Institution: Bellack, Alan S.; Professor; Psychiatry; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2002; Project Start 20-APR-1999; Project End 31-MAR-2004 Summary: Substance abuse by individuals with schizophrenia has reached epidemic proportions, yet little is known about why they use substances or how they can be helped to decrease use. The most widely accepted conceptualization of their substance abuse treatment needs is adapted from Prochaska and DiClemente's Transtheoretical Model (TTM). This model has proven to be quite robust in explaining the process of change in a variety of less impaired substance abusing populations, and several instruments have proven to be reliable and valid for assessing central components of the model. However, the TTM assumes intentional behavior change and full participation in the process of change by the substance abuser. Schizophrenia is marked by a number of symptomatic, neurocognitive, and psychosocial characteristics that would make it difficult for many individuals to successfully perform these complex activities, thereby raising questions about the applicability of the model for this population. Notably, patients with schizophrenia have significant impairments in cognitive function, including attention, memory, and higher level "executive" abilities, that may limit their ability to analyze the pros and cons of substance use, retain a focus on goals for decreased use over time, and form realistic efficacy expectations based on past experience. The disorder also is frequently associated with avolition and anhedonia, which may interfere with the ability to sustain motivation to reduce use. The overall purpose of this project is to examine attitudes about substance use, motivation to reduce use, and the process of change among schizophrenia patients who meet DSM-IV criteria for current Cocaine Dependence or are in Early Remission. The specific focus is the validity of the TTM for this population, and the adequacy of the standard measures of stages and processes of change developed for less impaired groups. Four groups of subjects will be assessed at Baseline, 3-, 6-, 9-, and 12-months: 70 Schizophrenia patients with current Cocaine Dependence, 70 Schizophrenia patients who are in Early Remission from Cocaine, 70 patients with Major Depression and current Cocaine Dependence, and 70 patients with Major Depression who are in Early Remission from Cocaine.

Project Title: ROLE OF CREB IN NUCLEUS ACCUMBENS IN MOOD AND MOTIVATION Principal Investigator & Institution: Nestler, Eric J.; Chairman; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-JUL-2007 Summary: (provided by applicant): Project 1 focuses on the ability of the transcription factor CREB in the nucleus accumbens (NAc) to regulate mood and motivational state. We have considerable evidence that increased CREB function in this brain region, which occurs under several conditions of stress, causes a decrease in an animal's sensitivity to emotional stimuli, regardless of whether the stimuli are aversive or rewarding. Reduced CREB function has the opposite effect. These findings suggest that CREB in the NAc

17
may function as a key molecular gate between emotional stimuli and their behavioral responses. A possible relationship between this phenotype and symptoms of anhedonia and reduced motivation in depressed humans will be explored in further studies of animal models, including analysis of various stress models, sexual behavior, intracranial self-stimulation, and social interactions. Viral-mediated gene transfer and inducible, cell-targeted mutations in mice will be used in these experiments. Another goal of the proposed studies is to investigate the cellular specificity of stress regulation of CREB in the NAc, and its possible modification by antidepressant treatments. Related studies will explore the molecular mechanisms by which stress and antidepressants regulate CREB in this brain region. A third goal of the proposed studies is to identify target genes through which CREB produces these effects on mood and motivation. The genes encoding the opioid peptide dynorphin and the AMPA glutamate receptor subunit GluR1 are two such targets of CREB that will be examined in this Project. Additional targets will be identified with DNA microarrays. Among the targets identified in initial array experiments are BDNF and NPAS2, the major gene products of interest in Projects 2 and 4, respectively. As stated earlier, CREB function is a major theme in this Center. All of the subsequent Projects of this Grant represent extensions of our central hypothesis that CREB in the NAc is a key regulator of hedonic or affective state. Subsequent Projects extend this theme by examining other molecular constituents of NAc neurons, which are regulated by CREB and help control CREB activity, for their role in this complex behavioral, phenotype. In addition, the other Projects explore a related role for CREB in certain hypothalamic (Project 3) and VTA(ventral tegmental area) (Project 2) neurons, which, along with the NAc, form a neural circuit controlling appetitive behavior.

Project Title: ROLE OF NUCLEUS ACCUMBENS CREB IN DEPRESSION Principal Investigator & Institution: Carlezon, William A.; Mc Lean Hospital (Belmont, Ma) Belmont, Ma 02478 Timing: Fiscal Year 2002; Project Start 01-JUL-2001; Project End 30-JUN-2006 Summary: From applicant's abstract): The proposed studies are designed to examine if the transcription factor CREB (cAMP response element binding protein) in the nucleus accumbens shell (NASh) plays a role in depression. Although the NASh is involved in the hedonic (pleasurable) effects of food, sex, and addictive drugs, little is known about its involvement in mood disorders. We found previously that blockade of CREB function in the NASh increases cocaine reward in rats, whereas elevated CREB function in this region eliminates cocaine reward. Because anhedonia (a diminished ability to experience pleasure) is a hallmark symptom of depression, these data suggest that CREB (and genes regulated by CREB) in the NASh may be involved in depressive syndromes. To address this question, we have examined relationships between CREB function in the NASh and behavior in the Porsolt forced swim test (FST), a model of depression. In preliminary studies, we find that exposure to the FST causes immediate increases in phospho-CREB (P-CREB, an activated form of CREB) in the NASh. To examine the significance of this effect, we elevated CREB expression in the NASh by viral-mediated gene transfer. This treatment increases immobility in the FST (suggesting increased depression), whereas blockade of CREB function in the NASh (by overexpression of a dominant negative CREB) decreases immobility (suggesting an antidepressant effect). Together, our work suggests that CREB in the NASh is a molecular regulator of at least some symptoms of depression (anhedonia, despair). We propose to further examine the interaction of CREB (and CREB-regulated genes) in the NASh with two antidepressants

Anhedonia
(desipramine, fluoxetine) in the FST. First, we will determine if antidepressants block CREB-induced increases in immobility. Second, we will examine the time course of FSTinduced P-CREB elevations in the NASh, and determine if they are blocked by antidepressants. Third, we will determine if the FST increases expression of dynorphin, a target gene of CREB. Fourth, we will determine if blockade of the brain receptors for dynorphin (k opioid receptors) has antidepressant actions. Finally, we will use intracranial self-stimulation (ICSS) to examine if elevated CREB expression in the NASh produces symptoms of depression in a second behavioral assay. These studies may establish that elevated CREB expression in the NASh is a "molecular trigger" for depression, and identify novel targets for pharmacotherapies.

Project Title: ROLE OF PROTEOGLYCANS IN COCAINE DEPENDENCE Principal Investigator & Institution: Sanna, Pietro P.; Associate Professor; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2003; Project Start 15-AUG-2003; Project End 31-JUL-2005 Summary: (provided by applicant): In humans, chronic use of cocaine is often associated with a binge-like, uncontrollable pattern of use with overall tolerance and acute withdrawal. This cocaine withdrawal is characterized by severe depressive symptoms combined with irritability, anxiety, and anhedonia, lasting several hours to several days that may be one of the major motivating factors in the maintenance of the cocainedependence cycle. We have observed that the expression of Syndecan-3, a proteoglycan previously implicated in feeding behavior, is dramatically increased in the hypothalamus during withdrawal in animals self-administering cocaine and it was significantly higher in animals with an escalating pattern of cocaine self-administration. The present CEBRA proposal is aimed at investigating the role of hypothalamic Syndecan in cocaine intake. To this aim we propose to use adeno-associated (AAV) viral vectors expressing Syndecan -1, a peripheral form of Syndecan that is not cleaved by brain proteases and mimics the overexpression of Syndecan-3; constitutively shed Syndecan-1 ectodomain; or small interfering RNAs (siRNA) targeting Syndecan-3. The effect of hypothalamic injection of these constructs will be studied on cocaine selfadministration in animals with an escalating pattern of cocaine self-administration in comparison to animals that self-administer consistent low levels of cocaine. The elucidation of the neurobiological bases for the transition from non-dependent drug use to addiction is of crucial importance for the development of novel and more effective therapeutic approaches.

Project Title: SENSITIZATION OF THE HUMAN STRESS RESPONSE BY TRAUMA Principal Investigator & Institution: Ganzel, Barbara L.; Human Development; Cornell University Ithaca Office of Sponsored Programs Ithaca, Ny 14853 Timing: Fiscal Year 2002; Project Start 31-AUG-2002 Summary: The proposed study is a longitudinal analysis of response to a uniform single-event stressor (graduate entrance examination) by young women (n = 22) who have experienced an assault in the past three years. Comparison will be made to a group of women of similar age who have experienced a non-assault trauma in the past three years (n = 22), and to women who have not experienced a trauma in their lifetime (n= 22). The goals of this research are: (1) to replicate and expand findings of chronic reductions in hypothalamic-pituitary-adrenal (HPA) axis reactivity in women following
Studies
19
assault; and (2) to associate this dysregulation with specific socioemotional outcomes (mental health, daily mood, and substance use). Chronic sensitization of the HPA axis would be indicated here by reduced production of salivary cortisol in response to acute stress and would be expected to predict earlier onset and higher levels of anxiety and depression to acute stress, overall increases in anhedonia, and increased use of addictive drugs relative to controls (particularly opiates and alcohol). Outcomes of this investigation include indicators of depression, anxiety, and drug/alcohol use, and will have relevance to the prediction and prevention of mental disorder and substance abuse.

Project Title: SOCIAL ANHEDONIA AND SCHIZOPHRENIA PRONENESS Principal Investigator & Institution: Blanchard, Jack J.; Associate Professor; Psychology; University of Maryland College Pk Campus College Park, Md 20742 Timing: Fiscal Year 2002; Project Start 30-SEP-1994; Project End 31-MAR-2006 Summary: The accurate identification of individuals prone to the development of schizophrenia is necessary for the study of environmental and biological factors that heighten or reduce the probability of developing this disorder. The detection of such vulnerable individuals would also help in prevention efforts. Unfortunately, prior research on the psychometric detection of schizophrenia-proneness has been limited in that what has been detected is more generally psychosis-proneness. Also, there are concerns that prior research is limited by the study of non-minority college students that are not representative of the general population. In this revised application it is proposed that social anhedonia may be a promising indicator of the latent liability for schizophrenia. The role of social anhedonia in the development of schizophrenia will be studied in a randomly ascertained community sample of 18 year-olds who will be selected independently of race, education, or socio-economic status. First, this study will examine the hypothesis that taxometrically identified socially anhedonic individuals are at risk for schizophrenia and schizophrenia-spectrum disorders. Subjects (social anhedonics and controls) will be assessed for schizophrenia and other Axis I disorders, schizophrenia-spectrum personality disorders, and psychotic-like experiences at a base assessment and again at a 3-year follow-up. Second, to understand the range of outcomes in at-risk individuals, other individual difference variables will be assessed that may potentiate the expression of schizophrenia and schizophrenia-spectrum disorders. It is hypothesized that, in vulnerable individuals, reduced social support, elevated trait negative affect, and attentional impairment at the base assessment will increase the probability of clinically diagnosable illnesses and generally poorer functioning at the follow-up assessment. Third, the proposed investigation will examine the hypothesized genetic risk for schizophrenia associated with social anhedonia by directly assessing schizophrenia-related diagnoses and characteristics in the biological parents of social anhedonics and controls.

The specific aims of this proposal to be carried out in the primary care setting are: o to systematically describe and validate a depressive syndrome, apathetic depression, that does not meet standard criteria for Major Depression in older primary care patients; o to assess how physical illness, cognitive impairment, anxiety, and hopelessness among older primary care patients alters the course of depression and associated functional impairment over time; and, o to evaluate the clinical presentation of depression and associated symptoms in late life in relation to the assessment and treatment decisions of primary care physicians. An age-stratified sample of 3000 adults aged 65 years and older who have visited one of 30 participating primary care physicians will be interviewed with a revised version of the CES-D in the physician's office. Patients above a threshold will be asked to participate in a home assessment and follow-up study. Approximately 300 patients will have significant depressive symptoms and will be asked to participate in a longitudinal, observational study with a 10% random sample of persons without depression. The main study will include a baseline in-home assessment, a 3-monthly telephone follow-up, and a 12-month in-home follow-up evaluation of depression, function, and other factors. Information on assessment and treatment of depression will be obtained from participating physicians. We seek to identify, in primary care, an anhedonic depression syndrome which appears to be associated with physical illness and significant functional limitation and for which misidentification of depression could be avoided if the syndrome were better understood.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.3 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with anhedonia, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “anhedonia” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for anhedonia (hyperlinks lead to article summaries): •

3 PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND ANHEDONIA Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and anhedonia.
Finding Nutrition Studies on Anhedonia The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.4 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “anhedonia” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.
4 Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 4. DISSERTATIONS ON ANHEDONIA Overview In this chapter, we will give you a bibliography on recent dissertations relating to anhedonia. We will also provide you with information on how to use the Internet to stay current on dissertations. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical dissertations that use the generic term “anhedonia” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on anhedonia, we have not necessarily excluded nonmedical dissertations in this bibliography.
Dissertations on Anhedonia ProQuest Digital Dissertations, the largest archive of academic dissertations available, is located at the following Web address: http://wwwlib.umi.com/dissertations. From this archive, we have compiled the following list covering dissertations devoted to anhedonia. You will see that the information provided includes the dissertation’s title, its author, and the institution with which the author is associated. The following covers recent dissertations found when using this search procedure: •
The effect of a dopamine antagonist and an agonist on rats' perception of reward quantity an examination of the anhedonia hypothesis by Martin-Iverson, Mathew Thomas; PhD from The University of British Columbia (Canada), 1985 http://wwwlib.umi.com/dissertations/fullcit/NL24215

CHAPTER 5. PATENTS ON ANHEDONIA Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.5 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “anhedonia” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on anhedonia, we have not necessarily excluded nonmedical patents in this bibliography.
Patent Applications on Anhedonia As of December 2000, U.S. patent applications are open to public viewing.6 Applications are patent requests which have yet to be granted. (The process to achieve a patent can take several years.) The following patent applications have been filed since December 2000 relating to anhedonia:
5Adapted from the United States Patent and Trademark Office: http://www.uspto.gov/web/offices/pac/doc/general/whatis.htm. 6 This has been a common practice outside the United States prior to December 2000.

Anhedonia
Method for treating anhedonia using dopamine agonists Inventor(s): Lehr, Erich; (Waldalgesheim, DE), Mierau, Joachim; (Mainz, DE), Pieper, Michael P.; (Bingen, DE) Correspondence: Boehringer Ingelheim Corporation; 900 Ridgebury Road; P. O. Box 368; Ridgefield; CT; 06877; US Patent Application Number: 20030036548 Date filed: August 6, 2002 Abstract: A method of treating anhedonia in a patient in need thereof, comprising administering to the patient an effective amount of a dopamine agonist Excerpt(s): Benefit under 35 U.S.C.sctn. 119(e) of prior U.S. provisional application Serial No. 60/312,332, filed Aug. 14, 2001, is hereby claimed. The invention relates to the use of dopamine agonists for preparing a pharmaceutical composition for overcoming and/or alleviating anhedonia. The term anhedonia is used in the prior art to denote a series of symptomatic conditions. Thus, the word anhedonia is used, for example, to denote loss of pleasure in life as well as an inability to derive any enjoyment from experiences or stimulations which normally give pleasure. Occasionally, anhedonia is divided into social anhedonia (for example, the loss of pleasure in being with friends) and psychic anhedonia (for example, the loss of pleasure in observing the beauty of nature). As a symptom anhedonia is found in psychiatric clinical pictures such as severe depression, schizophrenia, and dependency diseases. It may possibly also occur as a result of serious stress and extreme situations. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html
Keeping Current In order to stay informed about patents and patent applications dealing with anhedonia, you can access the U.S. Patent Office archive via the Internet at the following Web address: http://www.uspto.gov/patft/index.html. You will see two broad options: (1) Issued Patent, and (2) Published Applications. To see a list of issued patents, perform the following steps: Under “Issued Patents,” click “Quick Search.” Then, type “anhedonia” (or synonyms) into the “Term 1” box. After clicking on the search button, scroll down to see the various patents which have been granted to date on anhedonia. You can also use this procedure to view pending patent applications concerning anhedonia. Simply go back to http://www.uspto.gov/patft/index.html. Select “Quick Search” under “Published Applications.” Then proceed with the steps listed above.

Coffee Break: Tutorials for Biologists15 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.16 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.17 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
15 Adapted 16
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 17 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.
57
APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on anhedonia can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to anhedonia. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to anhedonia. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “anhedonia”:
58
Anhedonia
Bipolar Disorder http://www.nlm.nih.gov/medlineplus/bipolardisorder.html Child Mental Health http://www.nlm.nih.gov/medlineplus/childmentalhealth.html Mental Health http://www.nlm.nih.gov/medlineplus/mentalhealth.html You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The NIH Search Utility The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to anhedonia. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information.

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to anhedonia. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with anhedonia. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about anhedonia. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “anhedonia” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “anhedonia”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “anhedonia” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months.

Anhedonia
Cocaine: An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake. [NIH] Complement: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors. [EU] Complementary and alternative medicine: CAM. Forms of treatment that are used in addition to (complementary) or instead of (alternative) standard treatments. These practices are not considered standard medical approaches. CAM includes dietary supplements, megadose vitamins, herbal preparations, special teas, massage therapy, magnet therapy, spiritual healing, and meditation. [NIH] Complementary medicine: Practices not generally recognized by the medical community as standard or conventional medical approaches and used to enhance or complement the standard treatments. Complementary medicine includes the taking of dietary supplements, megadose vitamins, and herbal preparations; the drinking of special teas; and practices such as massage therapy, magnet therapy, spiritual healing, and meditation. [NIH] Computational Biology: A field of biology concerned with the development of techniques for the collection and manipulation of biological data, and the use of such data to make biological discoveries or predictions. This field encompasses all computational methods and theories applicable to molecular biology and areas of computer-based techniques for solving biological problems including manipulation of models and datasets. [NIH] Concomitant: Accompanying; accessory; joined with another. [EU] Connective Tissue: Tissue that supports and binds other tissues. It consists of connective tissue cells embedded in a large amount of extracellular matrix. [NIH] Connective Tissue: Tissue that supports and binds other tissues.
