You may have heard the saying, “What’s good for the heart is good for the brain.” A new study suggests that may be especially true for women. Mayo Clinic scientists reported that women with cardiovascular disease — or its major risk factors — were at much greater risk for declines in their memory and cognitive skills during midlife than men with these conditions.
Conversely, heart-healthy habits dramatically reduce risk for cognitive decline and dementia in men and women, as well as offering powerful protection against heart attacks, strokes, and chronic diseases. Here is a closer look at the heart-brain connection, with key takeaways from the BaleDoneen Method.
Published in the journal Neurology in January, the study included 1,857 men and women in their 50s and 60s who were participating in the Mayo Clinic Study of Aging. At the start of the study, they received nine tests to evaluate their memory, language, executive function and spatial skills, with the results combined to yield a global cognitive score.
Participants’ medical records were checked for cardiovascular (CV) conditions (such as heart disease, congestive heart failure, stroke, peripheral artery disease and arrhythmias) and CV risk factors (obesity, diabetes, high blood pressure, high cholesterol, high triglycerides and past or current smoking).
The volunteers, all of whom were free of dementia at the start of the study, were tracked for up to eight years, with the cognitive testing repeated every 15 months. The goal of the study was to look for associations between midlife cardiovascular health and mental acuity, and to find out if these associations differed in men and women.
Overall, 79 percent of the participants had at least one CV disorder or risk factor. Men had more risk factors than women: 83 percent for men vs. 75 percent for women.
Yet almost all the CV conditions and factors studied had a much greater impact on women’s brain function than men. For example, the annual decline in global cognitive function was more than twice as great in women with heart disease than in their male counterparts.
Moreover, the team found that diabetes and high levels of blood fats (such as cholesterol and triglycerides) were linked to declines in language skills in women, but not men. However, congestive heart failure was only associated with declining language skills in men.
While the study did not prove that cardiovascular conditions and risk factors cause cognitive decline, greater understanding of sex differences in its development is important to enhance the health of middle-aged adults, lead study author Michelle Meilke, PhD stated in a news release. “Thus, while all men and women should be treated for cardiovascular conditions and risk factors in midlife, additional monitoring of women may be needed as a potential means of preventing cognitive decline.”
Also known as cardiovascular disease (CVD), heart disease remains underdiagnosed and undertreated in women. The BaleDoneen Method is striving to change that by empowering women with the facts they need to take charge of their health TODAY. Follow these crucial steps to protect your heart and brain health — and please share them with women you care about.
