June is Alzheimer's disease Awareness Month. In honor of the estimated 5.7M Americans are living with Alzheimer's today and an estimated 14 million by 2050, Dr. Constantine Lyketsos, director of Memory and Alzheimer's Treatment Center and director of the department of psychiatry and behavioral sciences at Johns Hopkins Bayview discusses the difference between Alzheimer's and other dementias, recent research to uncover the causes and treatments for Alzheimer's disease, efforts to intervene in the progression of changes in the brain, and progress in diagnosing Alzheimer's earlier in life.
