This book was released on 2014 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Schizophrenia affects approximately 1% of the population and is one of the top five causes of disability worldwide. Patient response to any particular drug is variable and currently unpredictable. Our overall goal is to identify imaging biomarkers that will distinguish patients with schizophrenia who will respond to an antipsychotic drug from those who will not. When considering potential biomarkers, it is important to note that schizophrenia is known to involve altered neuronal connections, thought to reflect pathologically relevant changes associated with the disease. We propose to utilize functional connectivity as a biomarker for treatment response to antipsychotic drugs in schizophrenia. Our previous imaging studies have made significant progress by identifying several brain regions that show changes in blood flow in response to antipsychotic drugs. The proposed research will build upon this work, by examining differences in connectivity between these regions, using a region-based analysis, and globally, using a network-based analysis, at three time points in antipsychotic drug treatment: (1) in the medication-free, pre-treatment baseline state, (2) after one week of treatment, and (3) after six weeks of treatment.

This book was released on 2014 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Schizophrenia is a severe debilitating mental illness that affects approximately 1% of people worldwide. Compared to healthy controls (HC), patients with schizophrenia (SZ) have memory deficits, specifically prominent disruptions in their episodic memory. These memory disruptions are thought to be caused by altered structure and function of areas within the memory network, specifically the prefrontal and temporal lobe including the hippocampus. Recently, identifying biomarkers of treatment response by using neuroimaging has become a prominent area of interest in schizophrenia. Biomarkers in schizophrenia could help by allowing for more efficient treatment using current method and also the development of novel treatments. The primary objective of this dissertation research was to use non-invasive magnetic resonance imaging techniques, such as magnetic resonance spectroscopy (MRS), functional magnetic resonance imaging (fMRI), and structural magnetic resonance imaging (sMRI), to examine structural and functional features of schizophrenia as it relates to the memory network and treatment response. In the first study, we conducted a multimodal fMRI blood oxygen leveldependent (BOLD) and MRS study in healthy controls and chronic patients with schizophrenia stable on medication and found that patients showed decreased BOLD signal during encoding and retrieval within prominent regions of the memory network during an episodic memory task. Also, we found a significant correlation between the metabolites N-acetylaspartate/creatine (NAA/Cr) and glutamate+ glutamine (Glx/Cr) in our healthy control group but not in schizophrenia. In the second study, we used an automated algorithm, FreeSurfer, to measure the volume of the basal ganglia in unmedicated patients with schizophrenia. We found that treatment response was significantly correlated with all regions of the basal ganglia measured (caudate, putamen, and pallidum) and that the caudate volume explains a significant amount of the variance in treatment response even when controlling for baseline symptom severity and duration of illness. In the third study, we measured effective connectivity within regions of the memory network in patients with schizophrenia off-medication and again after 1-week of treatment with an APD. We found that while off medication SZ showed decreased connectivity within the memory network and that after 1-week of medication that the connectivity within the memory network increased.

Book Synopsis Neuroprogression in Psychiatry by : Flávio Kapczinski
Download or read book Neuroprogression in Psychiatry written by Flávio Kapczinski and published by Oxford University Press. This book was released on 2019-03-05 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies regarding the neuropathology of specific neurological disorders suggest that both neurodevelopmental and neurodegenerative processes may play a role. However, in contrast to the neurodegeneration seen in neurological disorders such as Parkinson's and Alzheimer's disease, the term "neuroprogression" has been used to describe the neurodevelopmental aspect of pathological brain re-wiring that takes place in the context of severe psychiatric disorders, such as schizophrenia or bipolar disorder. Within psychiatry, patients with severe psychopathology, such as those depressed patients who eventually commit suicide, have been shown to present with increased inflammatory markers in the brain. A similar increase in inflammatory markers is also found in patients with bipolar disorders and schizophrenia. Thus, oxidative stress, inflammation, and changes in growth factors are thought to be the pathways of neuroprogression. Neuroprogression in Psychiatry provides a comprehensive summary of the current developments in the emerging field of neuroprogression. With contributions by leading researchers in the field, this book examines the role of neuroprogression across a wide range of specific psychiatric disorders, with chapters included on major depressive disorder, anxiety disorder, post-traumatic stress disorder, substance abuse, schizophrenia, and bipolar disorder.
Book Synopsis Glutamate-Related Biomarkers in Drug Development for Disorders of the Nervous System by : Institute of Medicine
Download or read book Glutamate-Related Biomarkers in Drug Development for Disorders of the Nervous System written by Institute of Medicine and published by National Academies Press. This book was released on 2011-08-05 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glutamate is the most pervasive neurotransmitter in the central nervous system (CNS). Despite this fact, no validated biological markers, or biomarkers, currently exist for measuring glutamate pathology in CNS disorders or injuries. Glutamate dysfunction has been associated with an extensive range of nervous system diseases and disorders. Problems with how the neurotransmitter glutamate functions in the brain have been linked to a wide variety of disorders, including schizophrenia, Alzheimer's, substance abuse, and traumatic brain injury. These conditions are widespread, affecting a large portion of the United States population, and remain difficult to treat. Efforts to understand, treat, and prevent glutamate-related disorders can be aided by the identification of valid biomarkers. The Institute of Medicine's Forum on Neuroscience and Nervous System Disorders held a workshop on June 21-22, 2010, to explore ways to accelerate the development, validation, and implementation of such biomarkers. Glutamate-Related Biomarkers in Drug Development for Disorders of the Nervous System: Workshop Summary investigates promising current and emerging technologies, and outlines strategies to procure resources and tools to advance drug development for associated nervous system disorders. Moreover, this report highlights presentations by expert panelists, and the open panel discussions that occurred during the workshop.

Book Synopsis A Research Agenda For DSM V by : David J. Kupfer
Download or read book A Research Agenda For DSM V written by David J. Kupfer and published by American Psychiatric Pub. This book was released on 2008-08-13 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the ongoing quest to improve our psychiatric diagnostic system, we are now searching for new approaches to understanding the etiological and pathophysiological mechanisms that can improve the validity of our diagnoses and the consequent power of our preventive and treatment interventions -- venturing beyond the current DSM paradigm and DSM-IV framework. This thought-provoking volume -- produced as a partnership between the American Psychiatric Association, the National Institute of Mental Health, the National Institute on Alcohol Abuse and Alcoholism, and the National Institute on Drug Abuse -- represents a far-reaching attempt to stimulate research and discussion in the field in preparation for the eventual start of the DSM-V process, still several years hence. The book Explores a variety of basic nomenclature issues, including the desirability of rating the quality and quantity of information available to support the different disorders in the DSM in order to indicate the disparity of empirical support across the diagnostic system. Offers a neuroscience research agenda to guide development of a pathophysiologically based classification for DSM-V, which reviews genetic, brain imaging, postmortem, and animal model research and includes strategic insights for a new research agenda. Presents highlights of recent progress in developmental neuroscience, genetics, psychology, psychopathology, and epidemiology, using a bioecological perspective to focus on the first two decades of life, when rapid changes in behavior, emotion and cognition occur. Discusses how to address two important gaps in the current DSM-IV: (1) the categorical method of diagnosing personality disorders and their relationship with Axis I disorders, and (2) the limited provision for the diagnosis of relational disorders -- suggesting a research agenda for personality disorders that considers replacing the current categorical approach with a dimensional classification of personality. Reevaluates the relationship between mental disorders and disability, asserting that research into disability and impairment would benefit from the diagnosis of mental disorders be uncoupled from a requirement for impairment or disability to foster a more vigorous research agenda on the etiologies, courses, and treatment of mental disorders as well as disabilities and to avert unintended consequences of delayed diagnosis and treatment. Examines the importance of culture in psychopathology and the main cultural variables at play in the diagnostic process, stating that training present and future professionals in the need to include cultural factors in the diagnostic process is a logical step in any attempt to develop comprehensive research programs in psychology, psychiatry, and related disciplines. This fascinating work, with contributions from an international group of research investigators, reaches into the core of psychiatry, providing invaluable background and insights for all psychology and psychiatry professionals -- food for thought and further research that will be relevant for years to come.

Book Synopsis Mismatch Negativity by : Risto Näätänen
Download or read book Mismatch Negativity written by Risto Näätänen and published by Oxford University Press. This book was released on 2019-03-19 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mismatch negativity (MMN) is the electrophysiological change-detection response of the brain. MMN is stimulated when there is any discernible change to a repetitive sequence of sound, occurring even in the absence of attention. MMN is an automatic response and causes an involuntary attentional shift, representing a function which is of vital significance. A parallel response can also be detected in the other sensory modalities- visual, somatosensory, and olfactory. MMN occurs in different species, and across the different developmental stages, from infancy to old age. Importantly, the MMN response is affected in different cognitive brain disorders, providing an index to the severity of the disorder and consequently, a guide to the effectiveness of different treatments. MMN has become extremely popular around the world for investigating a wide range of clinical populations. It is a versatile tool for studying perception, memory, and learning functions in both the healthy and dysfunctional brain. Furthermore, being elicited irrespective of attention, it is ideal for investigating inattentive participants, such as sleeping infants or patients in a coma, whose cognitive processes are otherwise hard to access. Written by pioneers and leading authorities in the subject, this book provides an introduction to MMN and its contribution within different clinical fields: developmental disorders, neurological disorders, psychiatric disorders, and aging.
