How much can staying active in adulthood realy cut dementia risk?

A long-term Framingham Heart Study analysis shows that regular physical activity beginning in midlife and continuing into older age significantly lowers the risk of dementia, including Alzheimer disease, with the most active individuals experiencing roughly 40–45% risk reduction. A phase 3 trial of the first oral PCSK9 inhibitor, enlicitide, demonstrated substantial LDL-C and apoB reductions in patients with heterozygous familial hypercholesterolemia already on statins, offering a well-tolerated oral option that helps most patients reach guideline targets. Finally, a large U.S. cohort study revealed persistent under-treatment of chronic hepatitis B—especially among women and non-Asian racial groups—highlighting the need for standardized assessment and timely antiviral therapy to close these gaps.
