Bassel W. Abou-Khalil, M.D.

Professor of Neurology and Director of the Epilepsy Center.


Dr. Abou-Khalil earned both his B.S. and his medical degree (1978) at the American University of Beirut in Beirut, Lebanon. He completed an internship and one year of residency in Internal Medicine at the American University Medical Center in Beirut. He began a Neurology residency at the University of Rochester Medical Center in Rochester, NY, which he completed at the University of Michigan Medical Center in Ann Arbor, MI, from 1980-82. He completed a fellowship in EEG and Epilepsy at the University of Michigan Medical Center from 1983-85, and then was a post-doctoral fellow in Clinical Neurophysiology at the Montreal Neurologic Institute in Montreal, Quebec from April to September 1986.

Dr. Abou-Khalil is board certified in Neurology, Clinical Neurophysiology, and Epilepsy. He is founder and Director of the Vanderbilt Epilepsy Monitoring Unit and Clinical Epilepsy Program and was the founding director of the Vanderbilt Clinical Neurophysiology Training Program, which was accredited by ACGME in 1996. Dr. Abou-Khalil is a member of the American Neurological Association, a fellow of the American Academy of Neurology (Epilepsy Section), a fellow of the American Epilepsy Society, and a fellow of the American Clinical Neurophysiology Society.


My research interests are predominantly in the area of clinical epilepsy, including epilepsy surgery, development of new therapies for epilepsy, and clinical epilepsy genetics.

With respect to epilepsy surgery, I am interested in the analysis of seizure signs and their localizing and lateralizing significance, the localization of language and memory functions in the brain before surgery, and the use of new imaging methods, such as functional MRI, to help localize the epileptogenic zone and brain functions to be preserved during surgery.

I have conducted numerous trials of experimental and new antiepileptic drugs in various forms of epilepsy. Drugs being investigated include cenobamate, padsevonil, esclicarbazepine and brivaracetam for refractory focal-onset seizures.
