The Massachusetts General Hospital neurologist said the free online questionnaire targets 14 modifiable risk factors that experts estimate account for 40% to 45% of dementia cases.
Users answer questions on habits such as exercise, diet, smoking, alcohol use, blood pressure and social isolation, then receive a score to help prioritise lifestyle changes.
Rosand said family history does not make dementia inevitable, while a June 2025 study linked a five-point higher score to lower risks of heart disease and several common cancers.

Brain Care Score (BCS): Quantifying Modifiable Risk Reduction for Dementia, Stroke, and Depression
Overview
The Brain Care Score (BCS) is a validated tool that integrates physical health, lifestyle habits, and social-emotional well-being to predict and reduce the risk of late-life depression, dementia, and stroke. Research shows that a 5-point increase in BCS significantly lowers these risks, with especially large benefits for Black adults in reducing stroke. Key factors like blood pressure control, smoking cessation, and purpose-driven social engagement contribute to higher BCS and better brain health. Beyond brain diseases, a higher BCS also reduces cardiovascular disease and certain cancers. Personalized strategies, such as stress management for high-stress individuals and targeted interventions for genetic risk carriers, enhance protective effects. Integrating BCS into primary care with support roles improves patient engagement, though socioeconomic barriers remain challenges to equitable access.
