Spontaneous Resolution of Drug-Resistant Epilepsy in Patients with Sturge-Weber Syndrome.

Abstract

Introduction: Sturge-Weber syndrome (SWS) is often associated with drug resistant epilepsy. The literature is unclear as to how often these patients can be weaned off of antiepileptic drugs (AEDs) to become seizure-free. Case Description: We describe two patients with SWS. After initial treatment with various AEDs, breakthrough seizures still occurred. However, after periods with no seizure activity, they were weaned off of their medications. They have been off for 4 and 3 years and seizure-free for 13 and 12 years, respectively. No surgical procedure was necessary. Conclusion: We hypothesize that spontaneous involution or pathological disconnection of the vascular malformations might underly the patients' recovery. The initial aggressive therapy, close follow-up, choice of AEDs, or natural evolution of the disease may have played a role in their recovery. Therefore, in patients with SWS and lesional structural epilepsy, medication freedom is possible and invasive management options including surgery should be discussed carefully.
