Brief Summary:
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.

Condition or disease Intervention/treatment Phase
TBI (Traumatic Brain Injury) Device: Deep brain stimulation Not Applicable

Detailed Description:

This preliminary safety study evaluates the use of the Medtronic Activa PC+S system and Medtronic Nexus-E system for central thalamic deep brain stimulation (CT-DBS) in the treatment of cognitive impairment secondary to traumatic brain injury (TBI). It involves a neurosurgical procedure in which electrodes are implanted in the brain, connected to an implanted pacemaker-like device in the chest. The proposed study, if successful, will provide supporting evidence for the development of a novel therapeutic approach utilizing CT-DBS to improve these enduring cognitive impairments arising in persons with multi-focal structural brain injuries. This research will address the critical gap of the lack of any available treatments. CT-DBS targets well-defined neuronal populations within the central thalamus that have known anatomical and physiological specializations, which not only provide a key role in arousal regulation during cognitively-mediated behaviors, but also exhibit a particular vulnerability to dysfunction in the setting of multi-focal, non-selective brain injuries.

Our proposed study aims to support development of CT-DBS as a novel therapeutic avenue for accessing cognitive reserve in patients with acquired brain injuries. In the proposed feasibility study of 6 subjects at a single investigational site, we will test the safety of CT-DBS in the severe traumatic brain injury (STBI) population with GOSE 6-7 level recovery and collect data to establish the translation of preclinical studies into human application of CT-DBS.
