Epilepsia partialis continua, focal slowing (EEG)

EEG of the patient recorded during a period of continuous focal twitching of left neck, tongue, and mouth. It demonstrates focal slowing in the right frontal-central region, with quasiperiodic sharp waves at approximately 1.5 per second, maximal at F4 and C4. (Contributed by Dr. Lawrence J Hirsch.)
