Mapping Psychopathology with fMRI and Effective Connectivity Analysis


Book Description

There is a growing appreciation that many psychiatric (and neurological) conditions can be understood as functional disconnection syndromes – as reflected in aberrant functional integration and synaptic connectivity. This Research Topic considers recent advances in understanding psychopathology in terms of aberrant effective connectivity – as measured noninvasively using functional magnetic resonance imaging (fMRI). Recently, there has been increasing interest in inferring directed connectivity (effective connectivity) from fMRI data. Effective connectivity refers to the influence that one neural system exerts over another and quantifies the directed coupling among brain regions – and how they change with pathophysiology. Compared to functional connectivity, effective connectivity allows one to understand how brain regions interact with each other in terms of context sensitive changes and directed coupling – and therefore may provide mechanistic insights into the neural basis of psychopathology. Established models of effective connectivity include psychophysiological interaction (PPI), structural equation modeling (SEM) and dynamic causal modelling (DCM). DCM is unique because it explicitly models the interaction among brain regions in terms of latent neuronal activity. Moreover, recent advances in DCM such as stochastic and spectral DCM, make it possible to characterize the interaction between different brain regions both at rest and during a cognitive task.







Developmental Psychopathology, Theory and Method


Book Description

The seminal reference for the latest research in developmental psychopathology Developmental Psychopathology is a four-volume compendium of the most complete and current research on every aspect of the field. Volume One: Theory and Method focuses on the theoretical and empirical work that has contributed to dramatic advancements in understanding of child and adult development, including findings in the areas of genetics and neurobiology, as well as social and contextual factors. Now in its third edition, this comprehensive reference has been fully updated to reflect the current state of the field and its increasingly multilevel and interdisciplinary nature and the increasing importance of translational research. Contributions from expert researchers and clinicians provide insight into how multiple levels of analysis may influence individual differences, the continuity or discontinuity of patterns, and the pathways by which the same developmental outcomes may be achieved. Advances in developmental psychopathology have burgeoned since the 2006 publication of the second edition ten years ago, and keeping up on the latest findings in multiple avenues of investigation can be burdensome to the busy professional and researcher from psychology and related fields. This reference solves the problem by collecting the best of the best, as edited by Dante Cicchetti, a recognized leader in the field, into one place, with a logical organization designed for easy reference. Get up to date on the latest research from the field Explore new models, emerging theory, and innovative approaches Learn new technical analysis and research design methods Understand the impact of life stage on mental health The complexity of a field as diverse as developmental psychopathology deepens with each emerging theory and new area of study, as made obvious by the exciting findings coming out of institutions and clinics around the world. Developmental Psychopathology Volume One: Theory and Method brings these findings together into a cohesive, broad-reaching reference.

Brain Network Dysfunction in Neuropsychiatric Illness


Book Description

Brain network function and dysfunction is the dominant model for understanding how the brain gives rise to normal and abnormal behavior. Moreover, neuropsychiatric illnesses continue to resist attempts to reveal an understanding of their bases. Thus, this timely volume provides a synthesis of the uses of multiple analytic methods as they are applied to neuroimaging data, to seek understanding of the neurobiological bases of psychiatric illnesses, understanding that can subsequently aid in their management and treatment. A principle focus is on the analyses and application of methods to functional magnetic resonance imaging (fMRI) data. fMRI remains the most widely used neuroimaging technique for estimating brain network function, and several of the methods covered can estimate brain network dysfunction in resting and task-active states. Additional chapters provide details on how these methods are (and can be) applied in the understanding of several neuropsychiatric disorders, including schizophrenia, mood disorders, autism, borderline personality disorder, and attention deficit hyperactivity disorder (ADHD). A final complement of chapters provides a collective overview of how this framework continues to provoke theoretical advances in our conception of the brain in psychiatry. This unique volume is designed to be a comprehensive resource for imaging researchers interested in psychiatry, and for psychiatrists interested in advanced imaging applications.

Principles, Practices, and Positions in Neuropsychiatric Research


Book Description

Principles, Practices and Positions in Neuropsychiatric Research contains the proceedings of a conference held in June 1970 at the Walter Reed Army Institute of Research, Washington, D.C., in tribute to Dr. David McKenzie Rioch upon his retirement as Director of the Neuropsychiatry Division of that institute. This book is composed of the original contributions presented at the conference, as well as several invited papers that could not be programmed at the meeting because of certain limitations. Topics covered in some papers focus on anatomy of the thalamus; glia-neuronal interaction; receptor characteristics and conduction velocities in bladder afferents; responses of photoreceptors; and specificity of responses of cells in the visual cortex. This text also discusses the channeling of responses elicited by hypothalamic stimulation; neurochemistry of reward and punishment; behavioral analysis of aphasia; and biology of sleep. The military psychiatry and changing systems of mental health care, as well as psychological issues in training for research in psychiatry are also addressed. The contributions in this book will serve to reflect the remarkable range of bio-social research interest and competence.




Comprehensive Handbook of Psychopathology


Book Description

The major purpose of this handbook is to provide a comprehensive review of current clinical descriptions, research, and theories of psychopathology. Descrip tive psychopathology is a field that is the foundation of clinical practice and re search in clinical psychology, psychiatry, psychiatric social work, psychiatric nursing, and allied professions in mental health. Psychopathology is often per ceived as "a stepchild" of the more glamorous areas of diagnosis or assessment and therapy or behavioral change. Nevertheless, it is doubtful that any meaningful advancements in these areas will occur until there is a thorough understanding of the behavioral disorders. The purpose of the present project was to devise a handbook that covered both general and specific topics in psychopathology and that would be useful to re searchers, practitioners, and graduate or other advanced students in the mental health professions. In order to implement this plan, we selected very carefully colleagues whom we respect for their expertise in particular fields. These include both clinicians and researchers with outstanding national reputations, as well as more junior behavioral scientists and clinicians who, in our opinion, will achieve similar recognition in the future. The chapters in this book lead us to believe that we have chosen wisely. We would like to express our appreciation to these authors for their outstanding contributions and cooperation.




Neuropsychiatric Disorders


Book Description

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.
