Alexander M. Papanastassiou, MD, is an assistant professor in the Department of Neurosurgery at the University of Texas Health Science Center at San Antonio. His areas of expertise are general neurosurgery and surgery for epilepsy, trigeminal neuralgia, and movement disorders including Parkinson’s disease.
Dr. Papanastassiou received his Bachelor of Arts and Sciences at Stanford University, where he graduated Phi Beta Kappa. He continued with his medical degree at the University of California San Francisco. After medical school, Dr. Papanastassiou completed residency training in neurosurgery at Harvard University at the Brigham and Women’s Hospital and Children’s Hospital Boston. He then completed a fellowship in epilepsy surgery at Yale University.
The primary focus of Dr. Papanastassiou’s clinical work is surgery for medically intractable epilepsy, movement disorders, and trigeminal neuralgia. He has expertise in resective surgery, radiosurgery, and neuromodulation, including deep brain stimulation and microvascular decompression. A multi-disciplinary approach is used, benefitting from advanced techniques in microneurosurgery, brain mapping, image-guided neurosurgery, and minimally invasive neurosurgery. Dr. Papanastassiou is also active in developing novel applicationas for neuromodulation.
His research is aimed at advancing our understanding of brain function using neuroanatomy, neurophysiology, and functional neuroimaging to maximize neuropsychological outcomes in patients with neurological illnesses.
Dr. Papanastassiou is a member of the American Association of Neurological Surgeons, Congress of Neurological Surgeons, and the American Society for Stereotactic and Functional Neurosurgery. He is also an active member of the American Epilepsy Society and the Movement Disorders Society.
