Stimulant drugs are widely used in the treatment of ADHD in children and adults. Hundreds of studies over the past 60 years have demonstrated their effectiveness in improving attention span, increasing impulse control, and reducing hyperactivity and restlessness. Despite widespread interest in these compounds, however, their mechanisms of action in the central nervous system have remained poorly understood. Recent advances in the basic and clinical neurosciences now afford the possibility of elucidating these mechanisms. The current volume is the first to bring this expanding knowledge to bear on the central question of why and how stimulants exert their therapeutic effects. The result is a careful, comprehensive, and insightful integration of material by well-known scientists that significantly advances our understanding of stimulant effects and charts a course for future research. Part I presents a comprehensive description of the clinical features of ADHD and the clinical response to stimulants. Part II details the cortical and subcortical neuroanatomy and functional neurophysiology of dopamine and norepinephrine systems with respect to the regulation of attention, arousal, activity, and impulse control and the effects of stimulants on these systems. Part III is devoted to clinical research, including recent studies of neuroimaging, genetics, pharmacodynamic and pharmacokinetic properties of stimulants, effects on cognitive functions, neurophysiological effects in humans with and without ADHD and in non-human primates, and comparison of stimulants and non-stimulants in the treatment of ADHD. Part IV is a masterful synthesis that presents alternative models of stimulant drug action and generates key hypotheses for continued research. The volume will be of keen interest to researchers and clinicians in psychiatry, psychology, and neurology, neuroscientists studying stimulants, and those pursuing development of new drugs to treat ADHD.
In this groundbreaking and controversial book, behavioral neurologist Dr. Richard Saul draws on five decades of experience treating thousands of patients labeled with Attention Deficit and Hyperactivity Disorder—one of the fastest growing and widely diagnosed conditions today—to argue that ADHD is actually a cluster of symptoms stemming from over 20 other conditions and disorders. According to recent data from the Centers for Disease Control and Prevention, an estimated 6.4 million children between the ages of four and seventeen have been diagnosed with attention deficit hyperactivity disorder. While many skeptics believe that ADHD is a fabrication of drug companies and the medical establishment, the symptoms of attention-deficit and hyperactivity are all too real for millions of individuals who often cannot function without treatment. If ADHD does not exist, then what is causing these debilitating symptoms? Over the course of half a century, physician Richard Saul has worked with thousands of patients demonstrating symptoms of ADHD. Based on his experience, he offers a shocking conclusion: ADHD is not a condition on its own, but rather a symptom complex caused by over twenty separate conditions—from poor eyesight and giftedness to bipolar disorder and depression—each requiring its own specific treatment. Drawing on in-depth scientific research and real-life stories from his numerous patients, ADHD Does not Exist synthesizes Dr. Saul's findings, and offers and clear advice for everyone seeking answers.
ADHD in children and adolescents is a neurodevelopmental disorder, which is recognized by the clinicians all over the world. ADHD is a clinical diagnosis based on reliable history, reports from home and school and a physical examination to rule out any other underlying medical conditions. ADHD can cause low self-esteem in the child and impair quality of life for the child and the family. It is known that ADHD is a chronic illness and that clinicians needed to use chronic illness principles in treating it. The last 10 years have seen an increase in the number of medications that have been approved for the treatment of ADHD. This book has tried to address some of the issues in ADHD.
Renowned authority Russell Barkley provides a radical shift of perspective on ADHD. He argues that the disorder is not at root attentional, but rather a developmental problem of self-control. Offering new directions for thinking about and working with those with ADHD, this model has far-reaching implications for clinical practice.
More than 1 in 7 American children get diagnosed with ADHD - three times what experts have said is appropriate - meaning that millions of kids are misdiagnosed and taking medications such as Adderall or Concerta for a psychiatric condition they probably do not have. The numbers rise every year. And still, many experts and drug companies deny any cause for concern. In fact, they say that adults and the rest of the world should embrace ADHD and that its medications will transform their lives. -- Provided by publisher.
The understanding of parallel processing and of the mechanisms underlying neural networks in the brain is certainly one of the most challenging problems of contemporary science. During the last decades significant progress has been made by the combination of different techniques, which have elucidated properties at a cellular and molecular level. However, in order to make significant progress in this field, it is necessary to gather more direct experimental data on the parallel processing occurring in the nervous system. Indeed the nervous system overcomes the limitations of its elementary components by employing a massive degree of parallelism, through the extremely rich set of synaptic interconnections between neurons. This book gathers a selection of the contributions presented during the NATO ASI School "Neuronal Circuits and Networks" held at the Ettore Majorana Center in Erice, Sicily, from June 15 to 27, 1997. The purpose of the School was to present an overview of recent results on single cell properties, the dynamics of neuronal networks and modelling of the nervous system. The School and the present book propose an interdisciplinary approach of experimental and theoretical aspects of brain functions combining different techniques and methodologies.
Millions of children take Ritalin for Attention-Deficit Hyperactivity Disorder. The drug's manufacturer, Novartis, claims that Ritalin is the "solution" to this widespread problem. But hidden behind the well-oiled public-relations machine is a potentially devastating reality: children are being given a drug that can cause the same bad effects as amphetamine and cocaine, including behavioral disorders, growth suppression, neurological tics, agitation, addiction, and psychosis. Talking Back to Ritalin uncovers these and other startling facts and translates the research findings for parents and doctors alike. An advocate for education not medication, Dr. Breggin empowers parents to channel distracted, disenchanted, and energetic children into powerful, confident, and brilliant members of the family and society.
Debunks myths and misconceptions about ADHD, and discusses the controversies surrounding skyrocketing rates of diagnosis and medication treatment as well as the condition's cost to society.
This volume presents up-to-date, comprehensive and high quality reviews of the psychopharmacological evidence-base for each of the major psychiatric disorders, written by expert psychopharmacologists from around the world. Building on the success of the first edition, the volume summarizes the wealth of new developments in the field and sets them within the context of day-to-day clinical practice. All chapters have been fully updated and new contributions on personality disorders and substance dependence added. Each chapter provides information about optimal first line pharmacological interventions, maintenance pharmacotherapy and the management of treatment-refractory patients. The content is organized according to the DSM-V listing of psychiatric disorders, and covers all major conditions including schizophrenia, mood disorders, anxiety disorders, eating disorders and Alzheimer's disorder. These issues lie at the heart of clinical psychopharmacology, making this book invaluable to all practising and trainee clinicians, in a mental health setting or a less specialised environment.
