While most benefits diminished after 12 months without sustained volunteering, ongoing engagement preserved positive effects. This highlights the potential of structured volunteering to combat loneliness and enhance social connectivity among older adults.

The Harvard Health article "What's Your Brain Care Score?" introduces the McCance Brain Care Score, a 21-point assessment tool developed to help individuals identify actionable steps to reduce the risks of stroke, dementia, and depression. The score evaluates 12 modifiable factors across three domains: physical health (blood pressure, blood sugar, cholesterol, body mass index), lifestyle choices (nutrition, alcohol intake, smoking, aerobic activities, sleep), and social-emotional health (stress-management, social relationships, meaning in life). Each factor is assigned a point value, with higher total scores indicating better brain care. Significantly, a study involving nearly 400,000 adults aged 40 to 69 found that higher Brain Care Scores correlated with lower risks of developing stroke and dementia over a 12.5-year follow-up period. For instance, among individuals in their 60s, a five-point increase in the score was linked to a 33% reduction in stroke risk. These findings suggest that addressing modifiable factors can substantially enhance brain health and cognitive performance.To improve brain health, individuals are encouraged to monitor and manage cardiovascular health metrics, adopt a balanced diet, engage in regular physical activity, ensure sufficient sleep, foster strong social connections, and effectively manage stress. Given Harvard Health's reputable standing and the robust evidence supporting the McCance Brain Care Score, these recommendations are credible and practical for those seeking to enhance brain health and reduce the risk of neurological conditions.

The Harvard Health article emphasizes the importance of social connections for maintaining brain health and cognitive function.
