Since its inception in the 1930s, clinical electroencephalography has continued to be an indispensible diagnostic tool in the study of epilepsy. The past fifteen years have seen an explosion of knowledge in the basic neurosciences, paralleled by the development of sophisticated diagnostic tools for, and innovative therapeutic approaches to, the clinical problem of epilepsy. These include wider applications of computer technology in data processing, long term intra- and extra-cranial monitoring of EEG combined with closed circuit TV, etc. The four sections of this book are designed to cover the Classification, Recording, Interpretation and EEG Diagnosis, Treatment and Prognosis of epilepsy. This study presents epilepsy within a comprehensive clinical neurophysiological framework, with reference to the dramatic developments in EEG technology and related neurodiagnostic approaches.
