Initial Clinical Manifestations of Seizures Originating from the Occipital Area
First published: September 1987
Summary
1. Oculogyric deviation was the most common initial seizure manifestation.
2. Oculogyric symptoms were accompanied by focal runs of 8–20 Hz spike patterns, and oculoclonic symptoms by 2.5–4 Hz patterns of high-amplitude slow waves.
3. Contralateral deviation toward ictal EEG foci was found in 9 (64%) out of 14 seizures, and ipsilateral deviation in 5 (36%). Patients with ipsilateral deviation were all younger than 13 years of age.
