Typical absence seizures in childhood absence epilepsy, not the syndrome (EEG)

A 2.5-year-old girl with normal development and a 1-month history of vague events. The frequency was initially 1 episode per day and, during the 7 days preceding EEG, had increased to 5 to 7 absences per day. EEG showed hyperventilation episodes with abrupt staring, mild unbalance while standing, and occasional slight eyebrow jerking. Her past history was noncontributory. Typical absence seizures are not included in childhood absence epilepsy with onset in infancy or early childhood. (Contributed by Dr. Athanasios Covanis.)
