Intermittent electrical brain stimulation improves memory

(Medical College of Georgia at Augusta University) Intermittent electrical stimulation of an area deep inside the brain that degenerates in Alzheimer's appears to improve working memory, scientists report.Conversely, continuous deep brain stimulation, like the type used for Parkinson's and currently under study in humans with Alzheimer's, impairs memory, according to study results in adult non-human primates reported in the journal Current Biology.
