Glutamate-Related Biomarkers in Drug Development for Disorders of the Nervous System


Book Description

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.




The Science and Practice of Lithium Therapy


Book Description

This book provides a clear and comprehensive guide to the clinical prescription of lithium that draws upon evidence-based knowledge of its mechanisms of action. The book is divided into two parts, on the science of lithium and the practice of lithium therapy. The former covers aspects such as the properties of the lithium ion, pharmacokinetics and pharmacodynamics, impact on neurotransmission, and gene expression modulation. The section on practice includes discussion of variability in response to lithium, use of lithium in the treatment of bipolar disorders, its value in suicide prevention, administration during pregnancy and in the pediatric age group, and side effects. Lithium is arguably the only true mood stabilizer, and its multifaceted effects across many clinical domains have given rise to a resurgence of interest in recent years, fuelled by both researchers and clinicians. Nevertheless, its use remains constrained by exaggerated concerns about potential side-effects. In reality, lithium is a simple molecule that is relatively straightforward to administer and monitor and has potentially profound benefits at a fraction of the cost of contemporary agents. This book dispels the many myths and concerns that surround its use and will be of interest for clinicians and researchers worldwide, and those that are recipients of lithium therapy.

Schizophrenia and Psychotic Spectrum Disorders


Book Description

Schizophrenia and Psychotic Spectrum Disorders aims to engage young caregivers in psychiatry, psychology, nursing and social work so that they will be able to become well informed about this significant--and at times confusing--illness. Because schizophrenia is considered to be one of the most complicated and severe psychiatric disorders, this book has the goal of summarizing key issues of the illness, such as its presentation, frequency and age of onset, and diagnostic characteristics. It also contains informative chapters about the pathophysiology of schizophrenia, ranging from brain development issues, genetics, and likely abnormalities in neurotransmitters. This book will give young professionals and those joining the field an excellent and accessible background to treatment. In this area, Schizophrenia and Psychotic Spectrum Disorders provides a comprehensive approach to diagnosis, treatment initiation, strategies for non-response, approaches of therapy, and importantly, ways to provide family therapy and support.




Magnesium in the Central Nervous System


Book Description

The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.




Neurobiology of Mental Illness


Book Description

Our understanding of the neurobiological basis of psychiatric disease has accelerated in the past five years. The fourth edition of Neurobiology of Mental Illness has been completely revamped given these advances and discoveries on the neurobiologic foundations of psychiatry. Like its predecessors the book begins with an overview of the basic science. The emerging technologies in Section 2 have been extensively redone to match the progress in the field including new chapters on the applications of stem cells, optogenetics, and image guided stimulation to our understanding and treatment of psychiatric disorders. Sections' 3 through 8 pertain to the major psychiatric syndromes-the psychoses, mood disorders, anxiety disorders, substance use disorders, dementias, and disorders of childhood-onset. Each of these sections includes our knowledge of their etiology, pathophysiology, and treatment. The final section discusses special topic areas including the neurobiology of sleep, resilience, social attachment, aggression, personality disorders and eating disorders. In all, there are 32 new chapters in this volume including unique insights on DSM-5, the Research Domain Criteria (RDoC) from NIMH, and a perspective on the continuing challenges of diagnosis given what we know of the brain and the mechanisms pertaining to mental illness. This book provides information from numerous levels of analysis including molecular biology and genetics, cellular physiology, neuroanatomy, neuropharmacology, epidemiology, and behavior. In doing so it translates information from the basic laboratory to the clinical laboratory and finally to clinical treatment. No other book distills the basic science and underpinnings of mental disorders and explains the clinical significance to the scope and breadth of this classic text. The result is an excellent and cutting-edge resource for psychiatric residents, psychiatric researchers and doctoral students in neurochemistry and the neurosciences.

Biology of the NMDA Receptor


Book Description

The NMDA receptor plays a critical role in the development of the central nervous system and in adult neuroplasticity, learning, and memory. Therefore, it is not surprising that this receptor has been widely studied. However, despite the importance of rhythms for the sustenance of life, this aspect of NMDAR function remains poorly studied. Written




Dopamine and Glutamate in Psychiatric Disorders


Book Description

An illuminating summary of our current understanding of the interactive role of dopamine and glutamate in psychiatric diseases and the therapeutic strategies and possibilities for future treatment. Among the new ideas presented are hypotheses on the role of dopamine and glutamate in aggression, the glutamate system in anxiety disorders, glutamate and neurodegeneration, and on the origin and progression of Parkinson's disease. Additional chapters offer novel insights into a variety of psychiatric diseases, including ADHD, stress, aggression, addiction, schizophrenia, depression, social phobias, dementias, bulimia, and neurodegenerative diseases like Parkinson's and Alzheimer's diseases. Each chapter summarizes the prevalence and symptoms of the disease and explains the involvement of dopamine and/or glutamate systems using the newer molecular approaches such as transgenic knockout or knockin mice and recent brain imaging techniques.




Synaptic Stress and Pathogenesis of Neuropsychiatric Disorders


Book Description

Recent studies show that changes in Glutamate/GABA synapses and related pathways may determine whether the synaptic plasticity that occurs as a response to stress is adaptive or maladaptive. Findings have shed new light on the mechanisms that determine the effects of stress on cognitive and affective function. Researchers have brought a wide range of techniques to bear on the study of this problem, including cutting-edge live imaging techniques, electrophysiology, glutamate release from isolated live synaptic terminals, development of transgenic and animal models and new behavioral methods. This book provides an overview of these recent findings and of the techniques used as well as a discussion of how the molecular, cellular, and functional effects of stress may trigger or precipitate neuropsychiatric disorders such as depression, schizophrenia, anxiety and PTSD.
