The effects of epilepsy surgery on the sensorimotor function of children.

The motor and sensory functions of 50 children were investigated before and six months after epilepsy surgery; 34 infants were assessed 24 months after surgery. Postoperatively, 20 children were seizure-free and 22 had a significant reduction of seizures. Epilepsy surgery was found to be an effective mode of treatment for intractable seizures in childhood, even in multiply handicapped individuals. Motor and sensory functions did not deteriorate after surgery; in fact, significant improvements were found in more than half of the children, including those with multiple handicaps. Improvements were most obvious in the seizure-free group, but were also noted in those with reduced seizure frequency. The younger children benefited more from surgery as regards sensorimotor function than did older children and adolescents.
