EEG IN GASTAUT TYPE-IDIOPATHIC CHILDHOOD OCCIPITAL EPILEPSY.

SEPTEMBER 2016 - VOL.12 | CASE REPORT

Gastaut type-idiopathic childhood occipital epilepsy (G-ICOE) is a rare form of idiopathic childhood occipital epilepsy. It is characterized by late-onset, brief, frequent, usually diurnal, elementary visual auras which may be associated with hemi-clonic  or generalized convulsion. Occasionally the clinical presentation can be overlapped with Panayiotopoulos syndrome. Typical EEG findings are occipital paroxysms. The prognosis remains uncertain, but most seizures are often responsive to antiepileptic treatment.

Figure 1-2:
The EEG reveal runs of repetitive, high amplitude sharp and slow wave complexes in the occipital regions which appear immediately when the eyes are closed and persist for as long as the eyes remain closed. These epileptiform activities suddenly disappear after the eyes are open. (10-20 electrodesystem; double banana montage; high-pass filter 1 Hz; low-pass filter 70 Hz, notch filter 50 Hz, sensitivity 7 µV)
