A survey of neurologists' views on epilepsy surgery and medically refractory epilepsy.

There is a 20-year delay between the diagnosis of epilepsy and surgical treatment. The aim of this study was to describe the different views held by neurologists regarding refractory epilepsy that may contribute to the delay in referring patients for epilepsy surgery. Neurologists in Michigan were mailed a 10-item survey inquiring about their definition of medically refractory epilepsy and their decision-making process in referring patients for epilepsy surgery. Eighty-four neurologists responded (20%). The majority defined medically refractory epilepsy as failure of three monotherapy antiepileptic drug (AEDs) trials and at least two polytherapy trials. Nineteen percent responded that all approved AEDs had to fail before a patient could be defined as medically refractory. Eighty-two percent of the respondents had referred patients for epilepsy surgery. Almost 50% were not satisfied with the level of communication from epilepsy centers. One-third reported serious complications resulting from surgery. These findings suggest that further education and improved communication from comprehensive epilepsy centers may shorten the time to referral and ultimately improve the lives of patients with epilepsy.
