About Functional Neurosurgery
The neurosurgery team at Baylor Medicine has long been a pioneer in functional neurosurgery, using targeted therapies to improve quality of life. Baylor is a national leader in deep brain stimulation (DBS), a surgical procedure used to treat a variety of movement disorders. Dr. Viswanathan was the first surgeon in Texas to perform image-guided DBS, and “asleep” DBS. In addition to DBS, our neurosurgeons are experts in utilizing advanced state-of-the-art neurosurgical treatment for patients with disabling neurological movement disorders, neuropsychiatric disorders and pain conditions.
