Generalized periodic epileptiform discharges

Generalized periodic epileptiform discharges (GPEDs) are very rare abnormal patterns found in EEG.^[1]^[2]

Types

Based on the interval between the discharges they are classified as:^[1]

Periodic short-interval diffuse discharges (PSIDDs)
Periodic long-interval diffuse discharges (PLIDDs)
Burst suppression patterns
