Electrical brain stimulation has been shown to boost memory and enhance learning. Now, scientists have turned their sights on neurodegenerative diseases. Researchers at Ohio State University’s Wexner Medical Center, found they could delay cognitive decline in Alzheimer’s by using deep brain stimulation. This could allow such patients to be independent for a longer period of time. Their results were published in The Journal of Alzheimer’s Disease.
