Beau Ances, MD, PhD, is using the latest brain scanning techniques to better understand how long-term HIV infection impairs memory and other mental functions. He’s also applying his expertise in neuroimaging to Alzheimer’s disease and other degenerative disorders.
Kevin Black’s family didn’t have any physicians in it. Well, one of his great-great-grandfathers had a medical license back in the late 1800s, but he had no formal training — and Black himself wasn’t planning on medical school.

The differences, which are especially pronounced in people with dementia, may provide a clear and powerful new method for diagnosing individuals in the very early stages of Alzheimer’s disease.
