Typical absence seizures of childhood absence epilepsy (1)

Two typical absence seizures during hyperventilation with breath counting in a 9-year-old girl with childhood absence epilepsy. In first absence seizure, counting is interrupted within the first 2 seconds by the onset of a 3 Hz generalized spike-wave discharge (GSWD). Note the atonic components and the marked automatisms. She recovers from total unresponsiveness immediately with the termination of the GSWD. In the second absence seizure, her eyes open spontaneously, and counting is interrupted within the first 2 seconds by the onset of 3 Hz GSWD. Note marked automatisms, including mute counting. She recovers from total unresponsiveness immediately with the termination of the GSWD. (Contributed by Dr. C P Panayiotopoulos. From: Panayiotopoulos CP.
