Alzheimer's Disease


#1

Share you experiences living with or being a caregiver to someone with Alzheimer’s Disease

In people age 65 and older, Alzheimer’s disease is the most common cause of dementia. People generally may develop symptoms after age 60, but some people may have early-onset forms of the disease, often as the result of a defective gene.

Although in most cases the exact cause of Alzheimer’s disease isn’t known, plaques and tangles are often found in the brains of people with Alzheimer’s. Plaques are clumps of a protein called beta-amyloid, and tangles are fibrous tangles made up of tau protein. Certain genetic factors also may make it more likely that
people will develop Alzheimer’s.

Alzheimer’s disease usually progresses slowly over about eight to 10 years. Your cognitive abilities slowly decline. Eventually, the affected areas of your brain don’t work properly, including parts of your brain that control memory, language, judgment and spatial abilities.
