The latest weapon in the fight against memory loss may be found over-the-counter in your drug store.
New evidence suggests that the nicotine patch could boost brain power.
A Vanderbilt study shows those who wore a nicotine patch for six months did better on memory and thinking skills tests; while those on a placebo patch did progressively worse.
"We think that nicotine can directly stimulate cells in the brain that are helpful for attention and memory,” said Dr. Paul Newhouse, from Vanderbilt University.
Researchers said those benefits do not mean people should start treating their own memory malfunctions with nicotine -- in patch or cigarette form.
