What is Alzheimer's disease?
Alzheimer's disease (also termed Alzheimer disease) is a progressive mental deterioration that can occur in middle-aged individuals, but usually occurs in individuals that are about 60 to 65 years old or older. Early or younger onset Alzheimer’s can occur in individuals aged about 40 – 65. The disease is due to generalized deterioration of brain function related to plaques that develop in the brain tissue. The cause of Alzheimer's is unknown. Alzheimer's disease is the most common cause of premature senility. About 5.4 million Americans age 65 and older have Alzheimer's and approximately 200,000 individuals have younger or early onset Alzheimer's disease. Statisticians predict by 2050 about 13.8 to 16 million people will have Alzheimer’s disease. Continue Reading
