Definition

Epileptiform discharges induced by hyperventilation (overbreathing) in cerebral electrical activity recorded along the scalp by electroencephalography (EEG). [from HPO]

Recent clinical studies

Etiology

Prolonged epileptiform EEG runs are associated with persistent seizures in juvenile myoclonic epilepsy.
