45 Unforgettable Actors Died By Alzheimer

Alzheimer’s disease (AD) is a brain disorder that slowly destroys memory and other important mental functions and, eventually, the ability to do simple tasks. Symptoms of a late-onset type of disease generally occur in a person in their mid-60s. Early onset is very rare and occurs between a person’s 30s and mid-60s. This disease is the cause of about 60-70% of all dementia cases. Among older adults, AD is the most common cause of dementia.

As per the Alzheimer’s Association, one in three seniors dies with Alzheimer’s or another type of dementia.
