Perampanel in lissencephaly-associated epilepsy

We retrospectively investigated whether perampanel (PER) could serve as an alternative for treating drug-resistant seizures in lissencephaly. We investigated the following data: age at onset of epilepsy, age at start of PER, etiology, brain MRI findings, seizure type, seizure frequency, adverse effects, and concomitant anti-epileptic drugs. There were 5 patients with lissencephaly, including 2 with Miller–Dieker syndrome. Four out of five patients exhibited ≥ 50% seizure reduction. Myoclonic seizures disappeared in 1 patient. PER was an effective adjunctive anti-seizure drug in our series of patients with lissencephaly.
