Dementia cases are projected to increase as the U.S. population ages, with an estimated one million new cases annually by 2060. However, age-specific dementia rates have been declining, with an 80-year-old today being less likely to have dementia compared to one from a generation ago. A 2024 commission from The Lancet estimated that up to 45% of dementia cases could be prevented or delayed by addressing 14 risk factors, particularly during midlife. Key factors include managing blood pressure and cholesterol, avoiding smoking, and maintaining physical activity. Recent studies suggest a potential link between the shingles vaccine and lower dementia risk, although more research is needed. While no drug currently reverses dementia, proactive health measures can help mitigate risks.
