Cognitive Effects of Treatment of Interictal Discharges

Summary

The purpose of this study is to determine if levetiracetam (for patients with focal seizures) or lamotrigine (for patients with generalized seizures) reduces the occurrence of interictal discharges. The study investigates the possible correlation between reduction of interictal discharges and improved cognitive performance.
