Alzheimer’s is a brain disease that causes problems with memory, thinking, and behavior. According to Barry Reisberg, M.D., clinical director of the New York University School of Medicine’s Silberstein Aging and Dementia Research Center, Alzheimer’s is a seven stage process. In the early stages, individuals may feel they are having memory lapses. At the most severe stage, individuals lose the ability to respond to their environment, carry on conservations and control movement. Although there are treatments to cover the symptoms of Alzheimer’s, there is currently no cure for the underlying disease.
