Keeping our brain healthy more important as we age

A Wisconsins-based columnist says brain health has a broader definition today than simply avoiding stroke, incorporating cognitive function, dementia risk, processing speed and multiple forms of memory. The article argues that maintaining the mind involves social engagement, purpose, and emotional resilience, including how stress and mood affect day-to-day clarity. It also links brain health to cardiovascular health, citing atherosclerosis and the role of open arteries and heart pumping capacity in delivering blood to the brain. It references a 2024 study suggesting 2.5 hours of moderate exercise weekly can improve health, reducing stress-related brain activity.
