Electroclinical features of idiopathic generalized epilepsies in the elderly: a geriatric hospital-based study.

Purpose: Idiopathic generalized epilepsies (IGE) are age-related epileptic syndromes mainly described in children and adolescence. Our aim is to describe their electroclinical features in the elderly.

Methods: Patients aged 70 years or more were prospectively selected in a geriatric EEG laboratory on the basis of rhythmic generalized spikes and waves discharges.
