"We rightly associate Alzheimer's disease with an older population. Most people who develop this progressive brain disorder are age 65 and older. Currently some 5.5 million Americans— two-thirds of them women—live with the disease.
But hidden within that estimate, a smaller number—approximately 200,000 adults—develop the condition under the age of 65. When this happens, it's called younger-onset, or early-onset Alzheimer's. 'Alzheimer's is just one type of dementia, and given the frequency of early-onset it's somewhat uncommon,'says H. Rai Kakkar, MD, a neurologist at Presbyterian/St. Luke's Medical Center."
