In Boston, researchers at Mass General Brigham are taking a two-track swing at Alzheimer’s: high-powered genetics in the lab and a hands-on prevention checklist in the clinic. The idea is simple enough, even if the science is not. Lab teams hunt for genetic clues while frontline clinicians use a patient tool called the Brain Care Score to turn mountains of data into everyday to-do lists.
Dr. Jonathan Rosand, a Mass General Brigham dementia specialist and co-founder of the McCance Center for Brain Health, told WCVB that "Our goal is to understand how genetics vary from person to person." He said the gene work runs alongside prevention and that lifestyle changes available right now can already help lower dementia risk.
What The Brain Care Score Tracks
The Brain Care Score pulls together a dozen modifiable factors across physical, lifestyle, and social-emotional categories so patients and doctors can zero in on realistic changes, according to the McCance Center for Brain Health. The center describes the score as a coaching tool that spotlights blood pressure control, quality sleep, regular aerobic activity, nutrition, and social connection rather than a mysterious black-box metric.
What The Research Shows
The Brain Care Score has already been road-tested at population scale. Its predictive power was evaluated in a UK Biobank analysis of nearly 400,000 people, with results published in Frontiers in Neurology. In that study, a five-point higher score was linked to a 14% lower overall risk of dementia. In younger participants, risk reductions climbed to nearly 59%, suggesting that starting early may deliver outsized benefits.
Prevention That Starts With Blood Pressure
Rosand told WCVB that simply getting blood pressure under control nationwide could trim roughly 20 to 25% of dementia cases. With more than 7.2 million Americans already living with Alzheimer’s, the potential payoff is enormous, according to the Alzheimer's Association.
How Bostonians Can Access The Score
Mass General is folding the Brain Care Score into regular care, including virtual group visits that walk patients through calculating and improving their score, according to Mass General Hospital's McCance Center. Clinicians say that working toward achievable five-point gains, such as quitting smoking, getting more aerobic activity, or treating high blood pressure, gives people a concrete target rather than a vague lecture about “being healthier.”
Rosand’s genetics work points toward long-term therapies that could someday change how Alzheimer’s is treated. For now, the Boston research community is putting a bright spotlight on prevention. Their message is that modest, measurable changes can shift a person’s risk curve, and Rosand told the TV crew that people should hold on to hope and start with what they can change today.
