Long-term outcome of hemispheric surgery at different ages in 61 epilepsy patients.

Objective: Hemispheric neurosurgery is an established treatment for severe epilepsy caused by extended unilateral brain pathology. However, it is still an unresolved question at which age surgery should best be performed. In light of decreasing plasticity and the cumulative impact of seizures and anticonvulsants on neurodevelopment, early surgery appears preferable.
