Anhedonia is a key symptom (and often risk factor) for various neuropsychiatric disorders, including depression, schizophrenia, substance use disorders, post-traumatic stress disorders, and Parkinson's Disease, among others. Across disorders, anhedonia has been associated with worse disease course, including poor response to pharmacological, psychological and neurostimulation treatments as well as completed suicide. Mounting evidence emerging from preclinical and translational sciences has clarified that "anhedonia" can be parsed into partially independent subcomponents, including incentive motivation, consummatory pleasure, reward learning, and effort-based decision making, pointing to distinct neurobiological substrates that could underlie anhedonic phenotypes. Taking an integrative approach that emphasizes cross-species integration and dimensional conceptualization of mental illnesses (e.g., Research Domain Criteria (RDoC)), this book represents the most comprehensive evaluation, synthesis and integration of theories and empirical findings focused on anhedonia. Organized across five parts, the handbook starts with chapters on the history, etiology, and assessments of anhedonia (Part I), followed by a section on the role of anhedonia in psychiatric and neurological disorders (Part II). Using the RDoC Matrix as a guide, Part III presents chapters synthetizing preclinical and clinical findings on different reward processing subdomains (e.g., reward responsiveness, reward valuation, reward learning). Part IV is focused on selected special topics, including historical and current perspectives on the transdiagnostic nature and importance of social anhedonia, the role of inflammation in the pathophysiology of anhedonia, the use of computational modeling to “dissect” anhedonia and improve its understanding, and links between anhedonia and suicide. Finally, Part V includes chapters on pharmacological, psychological and neurostimulation treatments for anhedonia.

The World Health Organization defines depression as a primary contributor to the global burden of disease and predicts it will become the second leading cause of death by 2020. The need to develop effective therapies has never been so pressing. Current antidepressant drugs have several limitations. This 2010 book looks at the future of mood-disorder research, covering the identification of new therapeutic targets, establishing new preclinical models, new medicinal chemistry opportunities, and fostering greater understanding of genetic influences. These strategies are likely to help build a better picture of the disease process, and lead to new opportunities for patient stratification and treatment. The ultimate goal for this strand of research is to develop more personalized and effective treatments for this chronic and debilitating condition. This is essential reading for all those involved in psychopharmacologic drug development, and mental health clinicians seeking a preview of discoveries soon to influence their practice.

This is the first comprehensive two-volume collection on anhedonia, a disorder that played an important role in psychopathology theories at the beginning of the twentieth century. Anhedonia is a condition in which the capacity of pleasure is partially or completely lost, and it refers to both a personality trait, and a “state symptom” in various neuropsychiatric and physical disorders. It has a putative neural substrate, originating in the dopaminergic mesolimbic and mesocortical reward circuit. Over the past three decades cognitive psychology and behavioral neuroscience have expanded our understanding of anhedonia and other reward-related processes. The aim of this new two-volume collection on anhedonia is to highlight the contributions of eminent scientists in this field as well as to provide readers with comprehensive accounts of recent developments as perceived by the authors. This monograph is divided into five parts. Volume I contains parts one and two (Conceptual Issues and Neurobiological Advances) including 14 chapters that serve as an introduction and overview of conceptual issues. Volume II contains three parts (Anhedonia in Psychotic Disorders, Anhedonia in Mood and Personality Disorders, and Anhedonia in Neurological and Physical Disorders) including 15 chapters that provide an overview of the construct, measurement of anhedonia in schizophrenia spectrum disorders, hedonic capacity and related factors in schizophrenia and schizoaffective disorder, anhedonia as an indicator of genetic liability for schizophrenia, and as a trait marker for depression, the role of an anhedonia in trauma-related disorders, anorexia nervosa, stress-induced eating disorders, schizotypal traits and risk of suicide. This book will be of interest to a broad spectrum of readers including psychiatrists, psychologists, neurologists, neuroscientists, endocrinologists, pharmacologists, general practitioners, geriatricians, graduate students, and health care providers in the fields of mental health.

Obsessive-compulsive disorder (OCD) affects one person in 40 and can cause great suffering. This volume provides the first comprehensive summary of our understanding of this enigmatic condition, summarizing current work ranging from genetics and neurobiology through cognitive psychology, treatment, personal experiences, and societal implications.

Provides a one-stop evidence-based guide to the management of all types of mood disorders.

A sex therapist and neuroscientist describes anhedonia, the inability to feel a satisfactory amount of pleasure--and provides the pathway back to fully enjoying sex, food, time with family and friends, and other pastimes, while also staving off depression, anxiety, and addiction. Assaulted with opportunities for pleasure everywhere--from sex to food or exotic escapes--our culture is becoming more depressed and anxious. Research has shown that many people are having less sex, and that those who do have a lot enjoy it less. For more than thirty years, Nan Wise has worked as a therapist helping people gain a satisfying sex life. In recent years, her work has shifted to the study of anhedonia--the inability to experience pleasure from activities usually found enjoyable--and why more people than ever suffer from it. In Why Good Sex Matters, Wise not only reveals the fundamental problem in how we think about sex and pleasure but also how we arrived at this problematic relationship to begin with. This fascinating book helps us reclaim our innate capacity for joy, fun, exuberance, curiosity, and humor, while showing how reaching our sexual potential makes us smarter, happier, and more productive people. Ultimately, it reveals how a new understanding of sex can lead to a more expansive experience of pleasure in all aspects of our lives.

This volume covers the current status of research in the neurobiology of motivated behaviors in humans and other animals in healthy condition. This includes consideration of the psychological processes that drive motivated behavior and the anatomical, electrophysiological and neurochemical mechanisms which drive these processes and regulate behavioural output. The volume also includes chapters on pathological disturbances in motivation including apathy, or motivational deficit as well as addictions, the pathological misdirection of motivated behavior. As with the chapters on healthy motivational processes, the chapters on disease provide a comprehensive up to date review of the neurobiological abnormalities that underlie motivation, as determined by studies of patient populations as well as animal models of disease. The book closes with a section on recent developments in treatments for motivational disorders.

The Handbook of Mental Health and Aging, Third Edition provides a foundational background for practitioners and researchers to understand mental health care in older adults as presented by leading experts in the field. Wherever possible, chapters integrate research into clinical practice. The book opens with conceptual factors, such as the epidemiology of mental health disorders in aging and cultural factors that impact mental health. The book transitions into neurobiological-based topics such as biomarkers, age-related structural changes in the brain, and current models of accelerated aging in mental health. Clinical topics include dementia, neuropsychology, psychotherapy, psychopharmacology, mood disorders, anxiety, schizophrenia, sleep disorders, and substance abuse. The book closes with current and future trends in geriatric mental health, including the brain functional connectome, repetitive transcranial magnetic stimulation (rTMS), technology-based interventions, and treatment innovations. - Identifies factors influencing mental health in older adults - Includes biological, sociological, and psychological factors - Reviews epidemiology of different mental health disorders - Supplies separate chapters on grief, schizophrenia, mood, anxiety, and sleep disorders - Discusses biomarkers and genetics of mental health and aging - Provides assessment and treatment approaches
