A whopping one in every five Americans 65 or older currently has mild cognitive impairment, and one in every seven has been diagnosed with dementia. If that sounds staggering, get this: By 2050, the number of Americans with dementia is expected to triple, according to the authors of a just-released scientific statement published in the journal Stroke.
Dementia, which is defined by the Alzheimer’s Association as a decline in mental aptitude enough that it impacts daily life, is a more costly collection of conditions than heart disease or cancer, with worldwide costs estimated at $818 billion in 2015. (By the way, Alzheimer’s is the most common cause of dementia, and is a specific disease. Dementia is a general term for the category of this cognitive impairment.)
To try to prevent decline, reduce stroke risk and more, the study authors suggest that all Americans work with their primary care doctors to keep tabs on 13 factors that have proven links to brain health. These include the American Heart Association’s Life’s Simple 7, plus six other factors:
-
Managing blood pressure
-
Keeping healthy cholesterol levels
-
Increasing physical activity
-
Eating a nutritious, balanced diet
-
Losing weight, if needed
-
Not smoking
-
Preventing or treating symptoms of depression, if present
-
Reducing social isolation, if present
-
Combating sleep disorders, if present
-
Increasing education and keeping the brain active
-
Treating hearing loss, if present

You shouldn’t wait until you’re 65 to discuss these action items or to introduce healthier habits, suggests one of the statement authors Ronald M. Lazar, Ph.D., FAHA, the Evelyn F. McKnight Endowed Chair for Learning and Memory in Aging and the director of the Evelyn F. McKnight Brain Institute at the University of Alabama at Birmingham School of Medicine.
“Prevention doesn’t start in older age; it exists along the healthcare continuum from pediatrics to adulthood. The evidence in this statement demonstrates that early attention to these factors improves later life outcomes,” says Lazar, who is also a professor of neurology and neurobiology at the University of Alabama at Birmingham. “Scientists are learning more about how to prevent cognitive decline before changes to the brain have begun. We have compiled the latest research and found Life’s Simple 7 plus other factors like sleep, mental health and education are a more comprehensive lifestyle strategy that optimizes brain health in addition to cardiovascular health.”
A sharp, healthy brain is responsible for a wide variety of tasks, all of which are crucial to thrive and maneuver independently through the world:
-
Memory
-
Thinking
-
Reasoning
-
Communication
-
Problem solving
“Many people think of high blood pressure, type 2 diabetes and other risk factors as affecting only heart health, yet these very same risk factors affect our brain health. Patients might be more likely to pay attention to the importance of addressing modifiable risk factors if they understood the links,” Lazar says. “I’ve given lectures, and what people tell me is, the one thing they do not want to lose during the course of their lives is their mind.”
