Sameer Sheth, MD, PhD, is a board-certified neurosurgeon in Houston, Texas. After completing his bachelor’s degree in Physics and Astronomy at Harvard University, Dr. Sheth earned both his medical degree and PhD from the University of California Los Angeles. Dr. Sheth then completed his residency and Fellowship in Stereotactic and Functional Neurosurgery at Massachusetts General Hospital, the teaching hospital of Harvard Medical School. As a clinician, Dr. Sheth treats patients with disorders such as epilepsy, Parkinson’s disease, essential tremor, and obsessive-compulsive disorder (OCD). He uses a combination of time-tested techniques and new minimally invasive approaches, including deep brain stimulation (DBS), laser therapy, robot-guided surgery, radiosurgery, and other neurosurgical procedures. As a researcher at Baylor College of Medicine, he develops novel therapies for neuropsychiatric disorders and studies the neurophysiological basis of how the human brain makes complex decisions. Recently, Dr. Sheth and his collaborators received an $8.5 million NIH grant to better understand the neurocircuitry of depression. Their study will look at possible causes for treatment-resistant depression and how physicians could use deep brain stimulation to treat this devastating illness. Conditions treated include Deep Brain stimulation for movement disorders and Laser Interstitial Thermal Therapy. Dr. Sheth is rated as a Distinguished provider by MediFind in the treatment of Parkinson's Disease. His top areas of expertise are Movement Disorders, Epilepsy, Parkinson's Disease, Deep Brain Stimulation, and Thalamotomy.
