A new study suggests lowering blood pressure may also lower the risk of dementia in the elderly.

More than 3 million Americans over the age of 70 have dementia.

An international research team found controlling high blood pressure can cut an elderly patient's odds of having dementia by 13 percent.

Doctors suggest improving circulation may help fight memory problems.

There are currently no proven methods for avoiding dementia, but other experts insist more research needs to be done.
