Does Alzheimer’s Disease Prevent Cancer?

Mar 12, 2012

The Framingham Heart Study, a very large study completed over several years, reviewed 1278 participants who had Alzheimer's Disease. They followed these persons for ten years. At the completion of data review they found that patients who survived a cancer diagnosis had a lower risk for Alzheimer's and also that persons with Alzheimer's had a lower risk for cancer. They speculate that a genetic risk for Alzheimer's, which causes cell death in the brain (neurodegeneration), may also cause cell death of developing cancer cells.
