Alzheimer’s Disease (AD) is the most common form of dementia and accounts for 60% to 80% of dementia cases. In this progressive disease, dementia symptoms gradually worsen over a number of years. Memory loss is mild during the early stages, but individuals with late-stage Alzheimer's lose the ability to carry on a conversation and respond to their environment. The greatest known risk factor is increasing age, and the majority of people with Alzheimer's are 65 and older. That said, up to 5% of people with the disease have early onset Alzheimer's, which often appears when someone is in their 40s or 50s1. Studies indicate that people aged 65 and older survive an average of four to eight years after diagnosis of Alzheimer’s disease, yet some live as long as 20 years or more, demonstrating the slow, insidious progression of the disease.
