Download

Illustrated is a generalized spike-wave discharge of a 15-month-old boy with a 2-month history of frequent episodes of sudden loss of contact associated with perioral and eyebrow rhythmic jerks. The discharge was associated with impairment of consciousness and concomitant eyebrow and perioral rhythmic jerky movements. The electroclinical event lasted up to 19 seconds. The absence seizures are similar to those of childhood absence epilepsy. He responded on an appropriate daily dose of sodium valproate. (Contributed by Dr. Athanasios Covanis.)
