What is the starting age for Alzheimer's disease?

Most cases of Alzheimer's disease are diagnosed over the age of 65; however, there is also early-onset Alzheimer's. These cases make up only about 5 percent of all cases and may be diagnosed as early as 30 to 40 years of age, but closer to 50 years is more common.
