Alzheimer's disease is a progressive, neurodegenerative disease characterized in the brain by abnormal clumps and tangled bundles of fibers consiting of misplaced proteins.
Age is the most important risk factor for Alzheimer's Disease with the number of people with the disease doubling every five years beyond 65.
Three genes have been discovered that cause early onset Alzheimer's Disease. Other genetic mutations that cause excessive accumulation of amyloid protein are associated with age-related or sporadic Alzheimer's Disease.
Symptoms of Alzheimer's Disease include memory loss, language deterioration, impaired ability to mentally manipulate visual information, poor judgment, confusion, restlessness, and mood swings.
Eventually Alzheimer's Disease destroys cognition, personality, and the ability to function.
The early symptoms of Alzheimer's Disease, which include forgetfulness and loss of concentration, are often missed because they resemble natural signs of aging.
