Risk Factors for Alzheimer's Disease
Age is the most important risk factor for Alzheimer's disease. In fact, the number of people with this disease doubles every 5 years after age 65.
Alzheimer's research scientists are studying the role of genetics in the development of Alzheimer's disease. Researchers have discovered three genes that cause early symptoms of (familial) Alzheimer's disease and other genetic mutations that cause excessive accumulations of amyloid protein. The buildup of these proteins is associated with age-related (sporadic) Alzheimer's disease.
Common Symptoms of Alzheimer's Disease
Common symptoms of Alzheimer's disease may include:
- Memory loss
- Poor judgment
- Confusion
- Deterioration of language skills
- Impaired ability to understand visual information
- Mood swings
- Restlessness.
Eventually, Alzheimer's disease destroys a person's ability to think, process information, and function.
It is important to note that
early signs of Alzheimer's disease, which include forgetfulness and loss of concentration, are often missed because they closely resemble the natural signs of aging.
Statistics on Alzheimer's Disease
Scientists believe that up to 4.5 million Americans suffer from Alzheimer's disease. Alzheimer's usually begins after age 60 and the risk of developing this condition increases with age. For example, about 5 percent of men and women ages 65 to 74 have Alzheimer's disease, and nearly half of those who are over 85 years of age may have the disease. However, it is important to note that Alzheimer's disease is not a normal part of aging.
While younger people may also get Alzheimer's disease, this is much less common.
