ELECTROENCEPHALOGRAPHY AND MAGNETOENCEPHALOGRAPHY IN EPILEPSY AND NONEPILEPTIC DISORDERS

Recent advances in electroencephalography (EEG) and magnetoencephalogr aphy are reviewed. Their relevance to epileptic and nonepileptic condi tions is considered. The use of intensive video-EEG monitoring for the study or diagnosis of epilepsy is addressed. Studies using invasive E EG procedures for seizure analysis with or without surgical therapy ar e described. The integration of EEG with computer technologies is incr easing, and studies using digital EEG recording and quantitative analy sis in Alzheimer's disease and other disorders are reviewed. Environme ntal and behavioral effects on EEG are considered. The role of EEG in sleep-related electrophysiological monitoring is presented. Progress i n magnetoencephalography is described, but as a newer technology its u sefulness in epilepsy and other disorders remains to be proved, especi ally for clinical applications.
