The intracarotid amobarbital (or Amytal) procedure is commonly referred to as the Wada test in tribute to Juhn Wada, the physician who devised the technique and performed the fIrst basic animal research and clinical studies with this method. Wada testing has become an integral part of the pre operative evaluation for epilepsy surgery. Interestingly, however, Wada initially developed this method as a technique to assess language dominance in psychiatric patients in order that electroconvulsant therapy could be applied unilaterally to the non-dominant hemisphere. Epilepsy surgery has matured as a viable treatment for intractable seizures and is no longer confmed to a few major universities and medical institutes. Yet, as is increasingly clear by examining the surveys of approaches used by epilepsy surgery centers (e.g., Rausch, 1987; Snyder, Novelly, & Harris, 1990), there is not only great heterogeneity in the methods used during Wada testing to assess language and memory functions, but there also seems to be a lack of consensus regarding the theoretical assumptions, and perhaps, even the goals of this procedure.
The field of neurology is being transformed, from a therapeutically nihilistic discipline with few effective treatments, to a therapeutic specialty which offers new, effective treatments for disorders of the brain and spinal cord. This remarkable transformation has bridged neuroscience, molecular medicine, and clinical investigation, and represents a major triumph for biomedical research. This book, which contains chapters by more than 29 internationally recognized authorities who have made major contributions to neurotherapeutics, tells the stories of how new treatments for disabling disorders of the nervous system, such as stroke, multiple sclerosis, Parkinson's disease, and migraine, were...
Textbook of Epilepsy Surgery covers all of the latest advances in the surgical management of epilepsy. The book provides a better understanding of epileptogenic mechanisms in etiologically different types of epilepsy and explains neuronavigation systems. It discusses new neuroimaging techniques, new surgical strategies, and more aggressive surgical approaches in cases with catastrophic epilepsies. The contributors also analyze the improved statistics of surgical outcome in different epilepsy types. This definitive textbook is an invaluable reference for neurologists, neurosurgeons, epilepsy specialists, and those interested in epilepsy and its surgical treatment.
Once feared and misunderstood even among the medical community, epilepsy has since largely been demystified. Besides the characteristic seizures, various cognitive, behavioral, and emotional difficulties are recognized as associated with the condition, and patients are finding relief in medical management and/or surgical intervention. Not surprisingly, neuropsychology has emerged as a major component in treatment planning, program development, and assessment of surgical candidates. Geared toward beginning as well as veteran clinicians, the Handbook on the Neuropsychology of Epilepsy offers readers a skills-based framework for assessment and treatment, using current evidence and standardized ...
This was an exciting project to work on, and I attempted to obtain a broad sampling of current research on the neuropsychology of epilepsy. Because the emphasis of the book takes a neuropsychological perspective on epilepsy, the coverage is not redundant with previous texts on this topic. The book is organized around three themes, although individual chapters certainly often extend beyond the part in which they are located. The three major topics are the nature of epilepsy, cognitive and emotional consequences of epilepsy, and treatment approaches to epilepsy and outcome. In Part I, following a historical overview of epilepsy in Chapter 1 by Sandra D. Haynes and me, Gerald C. McIntosh presents a conceptualization of the epilepsies from a neurologist's perspective. The characteristics of seizure types are discussed, and the etiology of secondary epilepsies is described. Epileptic syndromes are considered. McIntosh outlines clinical seizure patterns associated with seizures originating from different cortical regions.
Preclinical Speech Science: Anatomy, Physiology, Acoustics, and Perception, Third Edition is a high-quality text for undergraduate and graduate courses in speech and hearing science. Written in a user-friendly style by distinguished scientists/clinicians who have taught the course to thousands of students at premier academic programs, it is the text of choice for instructors and students. Additionally, it is applicable to a broad range of courses that cover the anatomy and physiology of speech production, speech acoustics, and swallowing as well as those that cover the hearing mechanism, psychoacoustics, and speech perception. The material in this book is designed to help future speech-langu...
MRI can play an important role in identifying and localizing epileptogenic foci. This book aims to provide the clinical and imaging information required in order to decide whether an MRI scan is appropriate and whether it is likely to be sufficient to detect a lesion. The first part of the book presents background information on epilepsy patients and explains how to perform an MRI examination. Detailed attention is paid to functional MRI and post-processing, and the examination of subcategories of patients is also discussed. The second part of the book then documents the MRI findings obtained in the full range of epileptogenic lesions with the aid of high-quality images. Throughout, emphasis is placed on guiding the reader in the correct interpretation of the imaging findings. Both radiologists and referring physicians will find this book to be an indispensable guide to the optimal use of MRI in epilepsy.
Epilepsy can be frightening to both the sufferer and their loved ones. However, knowing more about the symptoms and treatment can give people a sense of empowerment. This volume discusses what epilepsy is, how it can be treated, and what can be done for someone who is having a seizure. The informative book, supplemented with in-depth sidebars, full-color photographs, and detailed charts, dispels the myths surrounding epilepsy and gives readers a clearer picture of this often misunderstood disorder.
Develop a practical understanding of neuroscience and confidently prepare for your future career as a clinician, researcher, or instructor with this thoroughly updated, extensively illustrated bestseller. Favored by students and educators for its user-friendly approach to complex neurological concepts, Neuroscience for Communicative Disorders, 6th Edition, provides a simplified and meaningful overview of the basics of functional neuroscience enhanced by for problem solving studies that connect neuroscience to the specific disorders of cognitive communication you’ll encounter in practice. The 6th Edition introduces full-color images and reflects the latest findings and clinical applications in the field, making this trusted resource even more engaging and easy to use.
The focus of Volume I of the Handbook of Human Brain Function was on basic scientific principles of brain imaging as it relates to the study of human brain function. Once the scientific bases for a particular discipline are established, follow. Such is the status of brain imaging in the study of clinical applications human brain function. It is of interest to note that the 1952 Nobel Prize for Physics was awarded to Felix Bloch and Edward Purcell, who discovered that nuclei precessing in the radiofrequency range could emit a radiofrquency signal detected by a radio receiver. Their findings initiated a series of very basic re search studies on the characteristics of nuclear magnetic resonance...
