Epilepsy in patients with focal cortical dysplasia may be associated with autism spectrum disorder.

Introduction: Patients with epilepsy associated with focal cortical dysplasia (FCD) may be associated with autism spectrum disorder (ASD). Therefore, the purpose of this study was to compare surgically treated patients with epilepsy secondary to FCD and normal volunteers without epilepsy and to review the neuropathological findings of patients with FCD.

Methods: This study involved 38 patients with medically intractable focal onset epileptic seizures who underwent epilepsy surgery (Group 1).
