A 46-year-old man experienced intractable seizures since childhood. Due to lack of response to antiepilepsy drugs (AEDs), he underwent a surgical evaluation that was consistent with seizure onset in the left medial temporal lobe. While on topiramate and carbamazepine, his preoperative neuropsychological scores and sodium amytal (Wada) scores were low and may have excluded him from surgery. Repeat testing on lamotrigine and carbamazepine showed improvement in his scores, allowing him to undergo surgery. Physicians must therefore be cautious in evaluating such test scores while a patient is on topiramate.
