Valproic acid was first synthesized in 1882 by Burton, but there was no known clinical use until its anticonvulsant activity was fortuitously discovered by H. Meunier in 1963 in the laboratory of G. Carraz. The first clinical trials of the sodium salt of valproate were reported in 1964 by Carraz. It was marketed in France in 1967 and was released in the United States in 1978 for the treatment of epilepsy. Since then, valproate has established itself worldwide as a major antiepileptic drug against several types of seizures. Clinical experience with valproate has continued to grow in recent years, including use of valproate for diseases other than epilepsy, for example in bipolar disorders and...
Intercellular communication via bioactive substances occurs in virtually all multicellular systems. Chemical neurotransmission in the vertebrate nervous system represents a form of signaling of this type. The biology of chemical neurotransmission is complex, involving transmitter synthesis, transport, and release by the presynaptic neuron; signal generation in the target tissue; and mechanisms for termination of the response. The focus of this book is on one aspect of this scheme: the diverse electrophysiological effects induced by different neurotransmitters on targets cells. In recent years, astonishing progress has been made in elucidating the specific physiological signals mediated by ne...
This book provides a reference guide describing the current status of medication in all major psychiatric and neurological indications, together with comparisons of pharmacological treatment strategies in clinical settings in Europe, USA, Japan and China. In addition, it highlights herbal medicine as used in China and Japan, as well as complementary medicine and nutritional aspects. This novel approach offers international readers a global approach in a single dedicated publication and is also a valuable resource for anyone interested in comparing treatments for psychiatric disorders in three different cultural areas. There are three volumes devoted to Basic Principles and General Aspects, offering a general overview of psychopharmacotherapy (Vol. 1); Classes, Drugs and Special Aspects covering the role of psychotropic drugs in the field of psychiatry and neurology (Vol. 2) and Applied Psychopharmacotherapy focusing on applied psychopharmacotherapy (Vol. 3). These books are invaluable to psychiatrists, neurologists, neuroscientists, medical practitioners and clinical psychologists.
This book presents a comprehensive collection of current knowledge and leading research about the blood-brain barrier. The chapters are organized in four main parts providing basic information and novel insights about the physiology of the blood-brain barrier, the challenges related to finding and developing drugs crossing the blood-brain barrier, experimental methods to study the blood-brain barrier and the role of the blood-brain barrier in disease mechanisms and its consequences for drug development. In the first part the readers will discover the structure, function and developmental aspects of the blood-brain barrier and gain novel insights into the complexity and functionality of the n...
Over 12 million people with epilepsy have seizures that cannot be controlled by antiepileptic drugs. The term "drug-resistance" is abundantly used in the epilepsy literature but the definitions proposed differ considerably. It is used indifferently in a number of different settings: as a criterion for selection of patients eligible for new antiepileptic drug trials, for the selection of surgical candidates, for the design of epidemiological studies, for the design of studies on quality of life, for the definition of the epileptic encephalopathies (in comparison to more benign epilepsy syndromes), to mention but a few. As a result, available studies are usually not comparable and referral to epilepsy specialists is unacceptably delayed. The volume includes several focused chapters on all issues relating to drug-resistance and offers the basis for a consensus on a clinically meaningful core definition.
Since the fortuitous discovery of its anticonvulsant activIty in 1962, valproate has established itself worldwide as a major antiepileptic drug against several types of epileptic seizures. Clinical experience with valpro ate has continued to grow in recent years, including use of valproate for diseases other than epilepsy, for example in bipolar disorders and migraine. In this volume on valproate emphasis is placed on the scientific back ground leading to the discovery of val pro ate, its subsequent pharmacologi cal and toxicological characterization, and its clinical development into one of the most widely and successfully used anti epileptic drugs, a real mile stone in drug therapy. The cu...
A radically new cosmological view from a groundbreaking neuroscientist who places the human brain at the center of humanity's universe Renowned neuroscientist Miguel Nicolelis introduces a revolutionary new theory of how the human brain evolved to become an organic computer without rival in the known universe. He undertakes the first attempt to explain the entirety of human history, culture, and civilization based on a series of recently uncovered key principles of brain function. This new cosmology is centered around three fundamental properties of the human brain: its insurmountable malleability to adapt and learn; its exquisite ability to allow multiple individuals to synchronize their minds around a task, goal, or belief; and its incomparable capacity for abstraction. Combining insights from such diverse fields as neuroscience, mathematics, evolution, computer science, physics, history, art, and philosophy, Nicolelis presents a neurobiologically based manifesto for the uniqueness of the human mind and a cautionary tale of the threats that technology poses to present and future generations.
Since the discovery some 15 years ago of benzodiazepine modulatory sites associated with GABA A receptors, great effort has gone into understanding their molecular pharmacology and into developing new anxiolytic drugs that interact selectively with them. Prominent in this research has beenthe discovery that ~-carbolines, a different chemical class from benzodiazepines, also act at these receptors but that their effects are sometimes quite different from those of the benzodiazepines.This book documents the latest discoveries in the molecular biology of the GABA A receptor and reveals how an integration of the results of research inmolecular biology, synthetic chemistry, biochemical and behavioral pharmacology, and clinical pharmacology has paved the way forthe development of ~-carbolines from substances inducing anxiety and convulsions to a novel therapy for anxiety states, achieving a behavioral selectivity through selective actions at subtypes of receptors.
