Tóm tắt

Most published neuropsychologic studies on frontal lobe epilepsy have been performed on mixed groups of adults and adolescents with epilepsies of varying etiology. The cognitive profile of frontal lobe epilepsy in children has not been defined. The purpose of this study was to assess neuropsychologic performance in children with frontal lobe epilepsy. Intelligence and executive functions were examined in eight children (age 67/12 years to 1311/12 years) with frontal lobe epilepsy. Performance was related to the focus side, seizure frequency, and age of epilepsy onset. Frontal lobe epilepsy was associated with a range of frontal dysfunctions, but IQ was generally spared. Left focus was associated with deficits in categorization, verbal long-term memory, and detailed visuospatial analysis. Frequent seizures correlated with attention difficulties and inability to inhibit impulsive responses. Children whose epilepsy appeared before age 6 years had reduced ability to change behavioral strategies. Frontal epileptic activity alone can cause selective frontal deficits, the severity and nature of which are related to side, seizure frequency, and age of epilepsy onset. These findings require confirmation on larger series of selected children. (J Child Neurol 2002;17:661-667).
