Deep-brain stimulation could improve memory

While a team of Canadian doctors was using the technique of deep-brain stimulation to suppress an obese man's appetite, the man suddenly recalled in details a scene decades earlier instead of losing his appetite. Further tests showed his ability to learn was dramatically improved.

The lead author said the discovery was totally unexpected and the team is now applying the technique to treat patients with Alzheimer's disease in a trial. The findings, reported in the Annals of Neurology, might provide benefit to patients with memory disorders.
