SELF-LIMITED (FAMILIAL) INFANTILE EPILEPSY (SeLIE)

Background

The background EEG is normal.

CAUTION Diffuse slowing of the EEG background right arrow consider other epilepsy syndromes.

CAUTION Persistent focal slowing in one area right arrow consider structural brain abnormality.

Interictal

Interictal EEG is typically normal, a variant with midline spikes during slow wave sleep has been described.

CAUTION Focal spikes shifting from one region to another in sequential EEGs right arrow consider epilepsy of infancy with migrating focal seizures.

Ictal

Seizures are accompanied by focal discharges that often have onset in temporal or posterior regions. The location of the ictal EEG pattern may change from seizure to seizure but there is no migration of the ictal locatization within any seizure.
