Report Finds What's Good for the Heart is Good for the Brain

During February, Americans are urged to pay closer attention to their heart health. Experts say new findings suggest it can keep your brain in better shape.

Researchers in Arizona and elsewhere are searching for ways to prevent heart attacks and strokes, which could slow the onset of dementia.

With American Heart Month under way, the American Heart Association's statistics update says in the past decade, global rates from Alzheimer's and other forms of dementia have grown at a faster pace than heart-disease rates.

Columbia University Neurology Professor, and immediate past president of the American Heart Association Mitchell Elkind said it coincides with research that connects heart-disease risk factors and the likelihood of dementia.

"That boundary that we used to draw," said Elkind, "between vascular diseases of the brain, like stroke, and degenerative problems, like Alzheimer's disease, is beginning to fade away."

The report says efforts such as keeping blood pressure low can reduce the risk of dementia later in life. The study also found gender, racial and ethnic disparities that are prevalent among people with poor brains health

Elkind said another real concern is that a lack of access to good health care or avoiding preventive care during to the pandemic only make the situation worse.

"We are seeing an increase in cardiovascular disease and strokes," said Elkind, "and that might lead to an increase down the line in people with not just dementia, but all sorts of long-term, chronic health issues."

Researchers at the University of Arizona are working on a promising treatment to reduce the risk of dementia in patients who have had a stroke.

Kristian Doyle, associate professor of immunobiology, University of Arizona College of Medicine - Tucson, said they are investigating a drug that helps the brain safely store cholesterol after a stroke without provoking an inflammatory response.

But he was quick to add that prevention is still the best cure.

"What's good for vascular health is good for both organs," said Doyle. "That's the main point to get across, really, is how healthy your blood vessels are. And unhealthy vessels are the cause of strokes and heart attacks. And stroke is a risk factor for the development of Alzheimer's."

Doyle said up to one-third of the people who have a stroke will develop dementia in the months afterward, adding that strokes affect more than 15 million people in the world every year.
