Circling seizures.

Twelve cases with circling seizures are presented with their clinical, electroencephalographic and radiological findings. Four patients had symptomatic partial epilepsy, five had cryptogenic partial epilepsy, and the remaining three had idiopathic generalized epilepsy. Three of the patients with symptomatic partial epilepsy had frontal lesion, and one had parito-occipital lesion. Turning direction had no lateralizing value in patients with partial epilepsy. Based on our study we conclude that circling seizures may occur in different epileptic syndromes and epilepsies. In cases with symptomatic partial epilepsy, lesions are mostly located in frontal lobes but also in parietooccipital areas.
