Every day, Dr. Walter Koroshetz, 65, takes a pill as part of his effort to help keep his brain healthy and sharp.
The pill is his blood pressure medication. And Koroshetz, who directs the National Institute of Neurological Disorders and Stroke, says controlling high blood pressure helps him reduce his risk of dementia.
He also keeps his blood pressure down by exercising and paying attention to his weight and diet. "I'm a believer," he says.
