At what age does Alzheimer's disease usually start?
From what I’ve read, most cases of Alzheimer’s occur in very old people. It’s hard to tell at what age Alzheimer’s disease would usually start, since no one knows exactly when the disease got its start in anybody. People usually have the disease a long time before there are symptoms.
Also, of course, there is early on-set Alzheimer’s and that can start when someone is forty. But for the most part, what I’ve read has said that Alzheimer’s disease usually will start in your later years, maybe sixties onward.
