Three million Americans are diagnosed each year with a type of dementia.
It is a condition that can be managed, but not cured.
But, what if you find out you can reduce the risk of developing dementia?
The World Health Organization thinks they know how.
As one expert says, "What's good for your heart is probably also good for your brain."
The main recommendations in the new guidelines are to exercise and maintain a healthy diet, with an emphasis on the benefits of the Mediterranean diet: simple plant-based cooking, small meat and extensive use of olive oil.
The World Health Organization also recommends to stay away from tobacco, restricting your alcohol intake, and, maintaining healthy blood pressure.
While there is no cure for dementia, there is hope that better health can help prevent it.
