The month of November is known as Alzheimer's Awareness Month. President Ronald Reagan made that designation in 1983 and it is something that is still recognized today. According to the Alzheimer's Association, at that time there were less than two million people with the disease. Today it is estimated that 5.8 million Americans of all ages are living with Alzheimer's dementia in 2019. This number includes an estimated 5.6 million people age 65 and older and approximately 200,000 individuals under age 65 who have younger-onset Alzheimer's.
