An informative and comprehensive review from the leading researchers in the field, this book provides a complete one-stop guide to neuroimaging techniques and their application to a wide range of neuropsychiatric disorders. For each disorder or group of disorders, separate chapters review the most up-to-date findings from structural imaging, functional imaging and/or molecular imaging. Each section ends with an overview from a internationally-renowned luminary in the field, addressing the question of 'What do we know and where are we going?' Richly illustrated throughout, each chapter includes a 'summary box', providing readers with explicit take-home messages. This is an essential resource for clinicians, researchers and trainees who want to learn how neuroimaging tools lead to new discoveries about brain and behaviour associations in neuropsychiatric disorders.

A study that goes beyond the debate over functional specialization to describe the ways that emotion and cognition interact and are integrated in the brain. The idea that a specific brain circuit constitutes the emotional brain (and its corollary, that cognition resides elsewhere) shaped thinking about emotion and the brain for many years. Recent behavioral, neuropsychological, neuroanatomy, and neuroimaging research, however, suggests that emotion interacts with cognition in the brain. In this book, Luiz Pessoa moves beyond the debate over functional specialization, describing the many ways that emotion and cognition interact and are integrated in the brain. The amygdala is often viewed as the quintessential emotional region of the brain, but Pessoa reviews findings revealing that many of its functions contribute to attention and decision making, critical components of cognitive functions. He counters the idea of a subcortical pathway to the amygdala for affective visual stimuli with an alternate framework, the multiple waves model. Citing research on reward and motivation, Pessoa also proposes the dual competition model, which explains emotional and motivational processing in terms of their influence on competition processes at both perceptual and executive function levels. He considers the broader issue of structure-function mappings, and examines anatomical features of several regions often associated with emotional processing, highlighting their connectivity properties. As new theoretical frameworks of distributed processing evolve, Pessoa concludes, a truly dynamic network view of the brain will emerge, in which "emotion" and "cognition" may be used as labels in the context of certain behaviors, but will not map cleanly into compartmentalized pieces of the brain.

Neuropsychiatric disorders such as schizophrenia, bipolar disorder, depression, anxiety disorders, and other mental disorders constitute about 13% of the global burden of disease surpassing both cardiovascular disease and cancer. The total cost worldwide of these diseases is estimated to exceed 100 million disability-adjusted life years. In order to begin to address this important problem, the present Research Topic brings together a group of leading affective neuroscience researchers to present their state-of-the-art findings using an affective neuroscience approach to investigate the spectrum of neuropsychiatric disorders from patients to those at risk. They focus on different aspects of the emotional and social cognitive disturbances which are core features of neuropsychiatric disorders. While progress has been slow over last couple of decades, we are finally beginning to glimpse some of the underlying neural mechanisms of the emotional and social cognitive disturbances in patients and those at risk. With the technological advances in affective neuroscience and neuroimaging presented in this volume, we hope that progress will be much swifter in the coming years such that we can provide better care for patients and those at risk.

It is widely recognized that neuropsychiatric disturbances contribute substantially to disability among persons with traumatic brain injury (TBI). This issue of Psychiatric Clinics addresses the most common and the most clinically challenging neuropsychiatric sequelae of TBI. The overarching aim of this publication is to provide clinicians with information about the clinical characteristics, diagnostic assessment, neurobiology and treatment of these conditions that will be useful in their work with individuals and families affected by TBI. Topics include: Posttraumatic Encephalopathy; Cognitive Disorders after TBI; Emotional and Behavioral Dyscontrol after TBI; Mood Disorders following TBI; Apathy following TBI; Psychotic Disorders following TBI; Sleep and Fatigue following TBI; TBI and Posttraumatic Stress Disorder; Neuropsychiatry of Persistent Post-concussive Symptoms; Psychiatric Disorders following Pediatric TBI.

This new volume in the Handbook of Clinical Neurology presents a comprehensive review of the fundamental science and clinical treatment of psychiatric disorders. Advances in neuroscience have allowed for dramatic advances in the understanding of psychiatric disorders and treatment. Brain disorders, such as depression and schizophrenia, are the leading cause of disability worldwide. It is estimated that over 25% of the adult population in North America are diagnosed yearly with at least one mental disorder and similar results hold for Europe. Now that neurology and psychiatry agree that all mental disorders are in fact, "brain diseases," this volume provides a foundational introduction to the science defining these disorders and details best practices for psychiatric treatment. Provides a comprehensive review of the scientific foundations of psychiatric disorders and psychiatric treatment Includes detailed results from genetics, molecular biology, brain imaging, and neuropathological, immunological, epidemiological, metabolic, therapeutic and historical aspects of the major psychiatric disorders A "must have" reference and resource for neuroscientists, neurologists, psychiatrists, and clinical psychologists as well as all research scientists investigating disorders of the brain

Around the world societies are facing growing aging populations with the concomitant increase in neuropsychiatric disorders. Neuropsychiatric disorders are organic brain diseases with psychiatric symptoms, as in Alzheimer’s and Parkinson’s diseases, that cause cognitive impairment, including dementia, amnesic syndrome, and personality–behavioral changes. As a clinical science, neuropsychiatry aims to explore the complex interrelationship between behavior and brain function from a variety of perspectives, including those of psychology, neurology, and psychiatry. This concise and updated monograph comprises the latest findings in the field and includes chapters on delusional symptoms, mood disorders and neurotic symptoms, cognitive impairment, behavioral and personality changes, and recently, cerebral alterations revealed in PTSD patients and in endogenous psychoses through neuroimaging and neuropathology. These findings will certainly widen the realm of neuropsychiatry going forward and will prove of great value to specialists as well as to academics and trainees in neurology, psychiatry, neuropsychology, neuroradiology, neuropathology, neurophysiology, neurochemistry, and clinical genetics. Ultimately, neuropsychiatry aims to prevent and reduce the suffering of individuals with the psychiatric symptoms of cerebral disorders.
