An accidental discovery during brain surgery in Britain might help people with Alzheimer’s disease, according to an article in the Independent. A man’s memory was increased when electrodes were placed deep in the brain and electrical currents were applied. The purpose of the surgery was to diminish the patient’s appetite but the unintended results started scientists thinking that electrical stimulation of certain areas of the brain could improve memory. The theory is that an ongoing electrical stimulation similar to how a pacemaker works would help patients retain and recall memories. Three patients have been treated with this procedure and initial results are promising according to the story. Deep electrical brain stimulation for the treatment of various diseases is a relatively new procedure that has grown over the last ten years.
