A study coming from the VA Boston healthcare system could shock many cancer and Alzheimer's victims.
Many cancers, except for prostate and melanoma, have been linked to a decreased risk for developing Alzheimer's disease. This study though, indicates that the reason might be chemotherapy.
The study analyzed the records of 3.5 million veterans who were over the age of 65. Investigators found that it was specifically the chemotherapy treatment, not the radiation that prevented cancer patients from developing Alzheimer's.
"The message is not, should we use chemotherapy as a therapeutic for Alzheimer's disease? The message is really focused on, what does chemotherapy do when it's systematically introduced into the body and in the brain, and what can we learn from that for potential therapies for Alzheimer's disease," says Dr. Maria Carrillo with the Alzheimer's Association.
Another study presented at the Alzheimer's conference suggests the Type 2 diabetes drug Metformin may also reduce the risk for dementia.
