Executive functions in children with frontal and temporal lobe epilepsy

Even though frontal lobe epilepsy (FLE) is a relatively common seizure type, no formal psychometric studies of children with FLE have been reported. We compared 12 children with FLE and 15 children with temporal lobe epilepsy (TLE) on neuropsychological tests of attention, memory. executive functioning, and adaptive functioning. The results of these tests indicated that the children with FLE had deficits in planning and executive functions, whereas their verbal and nonverbal memory was intact. The opposite pattern was observed in children with TLE. Measures of executive functioning and impulse control were the best predictors of adaptive functioning. The findings suggest that children with FLE have a pattern of cognitive deficits that differs markedly from the pattern seen in children with TLE. Children with FLE have prominent deficits in executive functioning that appear to be related to poor behavioral adaptation.
