Deep Brain Stimulation for the Treatment of Traumatic Brain Injury

Trial ID or NCT#



not recruiting iconNOT RECRUITING


This study involves the treatment of cognitive impairment secondary to moderate to severe brain injury using central thalamic deep brain stimulation. Although all patients will receive stimulation continuously through a surgically implanted pacemaker-like device, half of the patients will have the device deactivated during a blinded assessment phase. The device will be reactivated following this assessment and patients will have the option to continue stimulation in an open-label continuation.
