Higher McCance Brain Care Score linked to lower stroke risk in women

Women with a higher McCance Brain Care Score (BCS) – a score that measures physical, lifestyle, and social-emotional factors – have a lower risk of experiencing a stroke or other cerebrovascular event reducing blood flow to the brain, according to a new study conducted by experts from Mass General Brigham. The results are published in Neurology, the medical journal of the American Academy of Neurology.

Our findings underscore that the McCance Brain Care Score is a valuable tool for predicting cerebrovascular event risk in women, for whom stroke remains a leading cause of death. Our study further highlights the need for broader, long-term research across diverse populations and to investigate how changes in scores over the lifespan impact the risk of stroke and related events."

One in five women between the ages of 55 and 75 in the United States is expected to experience a stroke. Previous research has shown that the McCance Brain Care Score can predict risk of stroke, dementia, and depression in a general population. Ranging from 0 to 21 points, the BCS incorporates 12 modifiable risk factors, including physical components (blood pressure, blood sugar, cholesterol levels, and body mass index [BMI]), lifestyle factors (alcohol intake, diet, smoking, physical activity, and sleep), and social-emotional factors (social relationships, stress, and sense of meaning in life).

Along with lead author Devanshi Choksi, MBBS, MPH, a research fellow in the Department of Neurology at MGH, Yechoor, and colleagues pooled data from 21,271 women with a median age of 57.9 from the Women's Health Study (WHS), a landmark clinical trial led by Brigham and Women's Hospital designed to test the effects of aspirin and vitamin E on heart disease and cancer prevention in women. Using data collected from the WHS, investigators calculated women's BCS and used follow-up data to compare scores and cerebrovascular event incidence.

They found that a higher score correlated with a reduced risk of cerebrovascular events across one's lifetime. At a median 22.4 years follow-up, 6.1 percent of participants had experienced a cerebrovascular event (stroke or transient ischemic attack). Those with a five-point higher baseline BCS (the mean baseline score was 15) were 37 percent less likely to experience a cerebrovascular event after adjusting for age, menopausal status, use of hormonal replacement therapy, and other cardiovascular disease risk factors.
