You Can Do Something About Your Dementia Risk

Key Points:

• Dementia cases in the US are projected to exceed 1 million annually by 2060 due to an aging population, but the likelihood of developing dementia at a given age has decreased significantly compared to previous generations.
• Age-specific dementia rates across wealthy countries have declined by about 13% per decade since the late 1980s, with similar reductions observed for Alzheimer's disease.
• Improvements are attributed to better cardiovascular health management, including medication, reduced smoking, and enhanced stroke care, alongside increased educational attainment linked to lower dementia risk.
• A 2024 Lancet commission suggests that addressing 14 midlife risk factors—such as high LDL cholesterol, hearing loss, and physical inactivity—could prevent or delay up to 45% of dementia cases.
• Emerging research indicates the shingles vaccine might lower dementia risk, highlighting that while dementia remains a threat, proactive health measures can reduce its impact.
