Neurocognitive evaluation in children with occipital lobe epilepsy

Abstract

PurposeThis study aimed to explore cognitive functions in patients with childhood epilepsy with occipital paroxysms (CEOP) and to compare the performance of these patients with that of patients with symptomatic occipital epilepsy (SOE) and healthy control subjects. MethodTwenty-eight patients with epilepsy (17 CEOP, 11 SOE) were enrolled. The control group had similar demographical characteristics. Cognitive functions evaluated with Wechsler Intelligence Scale for Children-revised edition (WISC-R), The Visual Aural Digit Span (VADS) and Bender Visual Motor Gestalt Test (BVMG). ResultsThe WISC-R showed lower performance IQ with WISC-R in patients with occipital epilepsy than in healthy controls. The VADS test only showed lower scores in children with symptomatic occipital epilepsy. Mean BVMG test scores were significantly abnormal in both subgroups of childhood epilepsy with occipital paroxysms (early-onset CEOP/late-onset CEOP) and the group with SOE. ConclusionPatients with CEOP, especially the late-onset form, have significant problems in the domains of visuomotor coordination, memory and attention. The academic performance of these patients should be monitored carefully in follow-up and appropriate educational support should be given as necessary.
