If You Want To Prevent Dementia, These Are The Questions You Should Ask Your Doctor

While it’s clear how certain habits mentioned above could affect your cognitive health (like wearing a helmet, for example), other factors are a little more nuanced ― but are just as important to manage.

For instance, socialization is a true indicator of brain health. “We are social beings … and there are even changes in metabolic activity and brain activity that occur when we’re isolated that are harmful,” Ellison said.

With isolation comes loneliness, which can put you at higher risk of cognitive decline and stroke, Ellison added. “It’s very important to cultivate a social network,” he said.

Garg also noted that those with close family and friend connections can also get more support when recovering from health issues, which is important for well-being, too.

The factors that seem to relate more to heart health, like blood pressure, are important, too. “Almost everything that’s good for the brain is actually also good for the heart,” Ellison said. “When the heart is functioning properly, it provides nutrients and oxygen, which fuel the brain and keep it healthy, and it helps remove toxic metabolites from the brain as well.”

“When the heart is not functioning properly, the circulation and oxygenation and metabolic care of the brain is compromised, and that can lead to cognitive changes,” Ellison continued. He added that one of the most common kinds of cognitive decline in older people is “vascular cognitive impairment, which is a direct result of compromised circulation in the brain.”

Garg said simple, small positive habits, like diet and exercise, can often bring the biggest health rewards. She recommends a Mediterranean diet and said you should talk to your doctor about the best exercise regimen for you, as it varies person to person. Additionally, if you smoke, you should talk to your doctor about quitting, to protect both your brain and your overall health, Garg said.

It’s also important to manage your emotions, and you can talk to your doctor about how to best do that, too. “There are so many different ways to curb anxiety and stress, but people don’t realize how much of an impact it can make on your body and your brain,” Garg said. Research shows that anxiety is linked to higher rates of dementia.

These are questions you should bring up throughout your life, not just once you reach a certain age.
