“But we can't do anything about getting older. If we live long enough, is forgetting due to Alzheimer's our brain's destiny? For most of us, it is not. Alzheimer's is not a part of normal aging. Only 2% of people with Alzheimer's have the purely inherited early-onset form of the disease. 98% of the time, Alzheimer's is caused by a combination of the genes we inherited and how we live. While we can't do anything about our DNA, science clearly shows that the way we live can dramatically affect the accumulation of amyloid plaques. This in turn means that, like cancer and heart disease, there are things we can do to prevent Alzheimer's.”
