Meet Dr. Bradley Lega
Dallas Neurosurgeon Specializing in Emerging Technologies

UT Southwestern Medical Center neurosurgeon Bradley Lega, M.D., specializes in evaluation and surgical treatment of epilepsy, brain tumors, and disorders of the spine.

One of his areas of expertise involves using novel brain mapping and computer-assisted navigation technologies to improve the safety and efficacy of neurosurgical treatments.

Dr. Lega is one of the few neurosurgeons in the country who uses stereoelectroencephalography, or stereo EEG, to locate the origin of epileptic seizures in the brain and determine if a patient is a candidate for surgery to treat the seizures. Less invasive than the traditional approach, stereo EEG involves electrodes placed in the brain to record electrical activity during seizures.

“Tools like stereo EEG help me perform brain surgery more safely,” he says. “As neurosurgeons, we want every bit of data possible to help us identify the part of the brain that is causing the seizures so we can do our job with confidence.”

Dr. Lega believes it is important to keep track of new developments in the field. 

“We’ve seen a revolution in our field in the last five to 10 years based on evidence of how a specific surgical procedure can impact quality of life. We can now treat brain tumors, spine disorders, epilepsy, and other conditions using emerging technologies that expand safe, effective options for patients, as well as reduce recovery times,” Dr. Lega says.

“I collect quality of life data, monitor my outcomes, and stay on top of the latest studies to inform my decisions for surgery and do what’s best for my patients.”

Dr. Lega’s research informs his surgical approaches. In order to determine strategies to help restore memory function after a brain injury or brain tumor, he is studying how the brain encodes and retrieves memories. This also helps him design surgeries for tumors and for seizures that take account of the brain’s memory functions.
