Education, Intelligence May Protect Cognition, But Not Prevent Alzheimer’s Disease

The investigators say, those who start out with greater cognitive reserve — a baseline of higher mental functioning — may have more they can afford to lose before Alzheimer’s disease symptoms begin to interfere with their daily lives compared with those who don’t have as much schooling or participate regularly in mentally challenging tasks.
The findings, published in the April issue of the Journal of Alzheimer’s Disease, suggest — but don’t prove — that exercising your brain might help keep people cognitively functional longer, but won’t ward off the inevitable decline of Alzheimer’s disease.
