Memory improving brain implants coming soon
By 2018, an implantable device may be able to improve the memories of people with traumatic brain injury, mild cognitive impairment, epilepsy, and Alzheimer’s disease.
Researchers plan to use safe levels of electrical stimulation to test new ways of improving brain function and memory in neurosurgery patients who already receive brain stimulation as part of their therapy for epilepsy. Their goal is to determine whether brain stimulation delivered when these individuals play memory games will improve their memory ability.
“If memory can be improved in patients who have electrodes implanted to treat epilepsy − and who frequently have mild memory impairment − then we will have gained valuable information on how to restore memory function in patients with traumatic brain injury or Alzheimer’s disease,” said Dr. Bradley Lega, Assistant Professor of Neurological Surgery, Neurology and Neurotherapeutics, and Psychiatry, who leads the Dallas arm of the study.
Dr. Lega is recruiting 15 patients per year with epilepsy to undergo stereo electroencephalography (sEEG), a minimally invasive technique for recording brain waves to diagnose epilepsy. Dr. Lega is one of the few neurosurgeons in the country who uses stereo EEG to locate the origin of epileptic seizures in the brain and to 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.
The data gathered at UT Southwestern will be combined with data from the University of Pennsylvania, Thomas Jefferson University in Philadelphia, the Mayo Clinic, Dartmouth University, Emory University, and Boston University to develop and test new treatments.
“The national research team believes that the therapeutic strategies being examined in this study will serve as the foundation for novel brain-machine interface devices that will improve memory function,” Dr. Lega said.
