title: "Grand mal type" of spike discharge as interseizure phenomenon.
abstract: Grand mal type of sequential spike discharges at 8-12 cps are rare as interseizure phenomena. When the grand mal component is prominent, it usually indicates a greater tendency for major convulsions. The case of a 15 year old girl who developed akinetic seizures along with her menarche and whose electroencephalogram showed recurring sharp waves at 10-11 cps, is reported, and its clinical significance discussed.
