Alzheimer's risk lowered with chemotherapy


A history of some cancers is associated with a decreased risk for developing Alzheimer's disease, and new research suggests chemotherapy may be the link.

Researchers at the V-A Boston Healthcare System analyzed health records of 3.5 million veterans over age 65. Having had most types of cancer was associated with a reduced risk for later developing Alzheimer's.

The lower risk was most significant among survivors of liver and pancreatic cancer. There was no link for prostate cancer and melanoma.

When investigators looked at cancer treatments -- they found it was chemotherapy but not radiation that appeared to offer the apparent protective benefit.

Another study presented at the Alzheimer's Conference suggests the Type II Diabetes drug metformin may also reduce the risk for dementia.

-This study is from the VA Boston Healthcare System, and is scheduled for presentation at the Alzheimer's Association International Conference in Boston.
