Recurrence of childhood absence epilepsy as pyknolepsy in adolescence

A developmentally normal adolescent boy with a history of childhood absence epilepsy presented with recurrence of pyknolepsy after a seven-year period of remission. The characteristics of his EEG showed the same 3-Hz generalised spike-wave discharge as in his previous EEG in childhood. To our knowledge, this is the first case report describing recurrence of childhood absence epilepsy as pyknolepsy in an adolescent.
