Self-induced photogenic epilepsy in infants.
We studied two infants with self-induced photogenic epilepsy and investigated their seizures with simultaneous EEG and videotape recording. A 2-year-old boy showed peculiar head-nodding behavior towards bright light before he manifested myoclonic absence or myoclonic seizures. A 14-month-old infant girl showed blinking in front of the television set before myoclonic jerks developed. Neither head nodding nor blinking was associated with paroxysmal discharges. We concluded that such preictal behavior was not part of the seizure.
