kkleiner writes "Scientists at the Ohio State University Wexner Medical Center have begun a trial to test whether or not a deep brain stimulation device – a “brain pacemaker” – can ward off the debilitating symptoms of Alzheimer’s disease. Their first patient, Kathy Sanford, received the implants last October. Prior to the surgery Sanford had been diagnosed with mild Alzheimer’s, and her symptoms were progressively getting worse. But after five months of continuous stimulation from the brain pacemaker her performance on cognitive tests have vastly improved."
