Dr. Jonathan Rosand, the founder of the Global Brain Care Coalition, developed the Brain Care Score as an assessment to help people lower their risk for dementia, stroke and depression. The Brain Care Score measures 12 physical, lifestyle and social factors that impact brain health. Managing these factors — including stress management, building social relationships and finding meaning and purpose in life — can help prevent the onset of dementia. Rosand shared with Horizons host William Brangham how doctors and patients can discuss this aspect of dementia prevention.

Alzheimer’s disease makes up the majority of dementia cases, and it remains a primary focus of funding and research. As documented in Robert Kolker’s book, “The Vanishing Family,” research does not prioritize rare brain diseases. “A lot of the investment is built around big swings, like things that are going to lead to big cures because that's going to get the biggest profits,” Kolker told Horizons host William Brangham.
