Key players include Dr. Paul Schulz at UTHealth Houston, whose recent research highlights stronger protection from high-dose flu vaccines. It's reported now amid fresh evidence from Schulz's study published earlier in April 2026.[[1]](https://www.doximity.com/newsfeed/7caa884a-c735-4670-a9ef-085aab35aa44/public)[[2]](https://www.nytimes.com/2026/04/17/well/mind/medications-dementia-risk-decrease.html)\n\n## Key points\n- Numerous studies find older adults vaccinated against flu had lower dementia risk years later than unvaccinated peers; one showed up to **40% lower risk**.[[1]](https://www.doximity.com/newsfeed/7caa884a-c735-4670-a9ef-085aab35aa44/public)\n- New research by Dr. Paul Schulz shows high-dose flu vaccine (recommended for ages 65+) cut Alzheimer's probability more than standard dose, suggesting vaccine-specific effect.[[3]](https://www.uth.edu/news/story/risk-of-alzheimers-dementia-significantly-reduced-after-high-dose-influenza-vaccination-compared-to-the-standard-dose-study-finds)[[2]](https://www.nytimes.com/2026/04/17/well/mind/medications-dementia-risk-decrease.html)\n- Blood pressure and cholesterol medications also tied to reduced Alzheimer's risk in studies.\n- Shingles vaccine appears protective, especially noted in secondary coverage of the article.[[2]](https://www.nytimes.com/2026/04/17/well/mind/medications-dementia-risk-decrease.html)\n- Anti-inflammatory drugs and diabetes medications (like SGLT2s, GLP-1s) linked to lower risk in some reports, though evidence mixed.[[4]](https://www.reddit.com/r/fitover65/comments/1so5cls/6_common_medications_that_may_lower_your_dementia)\n- Challenge: Healthy user bias—people taking these often follow medical advice better—complicates proving direct brain benefits.\n\n## Details and context\nThe Doximity page previews a paywalled *New York Times* piece by Dana G. Smith, focusing on observational studies associating vaccines and common drugs with dementia risk reduction. It stresses nuance: vaccinated or medicated people may simply engage more with healthcare, taking pills as prescribed.[[1]](https://www.doximity.com/newsfeed/7caa884a-c735-4670-a9ef-085aab35aa44/public)[[2]](https://www.nytimes.com/2026/04/17/well/mind/medications-dementia-risk-decrease.html)\n\nDr. Schulz's study compared high- vs. standard-dose flu vaccines in older adults, finding greater protection from the former—evidence against pure correlation since all got vaccinated. Shingles vaccine shows promise in related research, possibly via immune modulation.[[2]](https://www.nytimes.com/2026/04/17/well/mind/medications-dementia-risk-decrease.html)\n\nCholesterol drugs like statins and blood pressure meds address vascular risks tied to dementia. Diabetes and anti-inflammatory drugs may help by curbing inflammation or metabolic issues, but randomized trials are lacking.[[4]](https://www.reddit.com/r/fitover65/comments/1so5cls/6_common_medications_that_may_lower_your_dementia)\n\n## Key quotes\n“People who tend to get vaccinated are the people who go to see a doctor, and then they follow the directions to take their blood pressure pills and cholesterol pills, which also reduce the risk of Alzheimer’s,” said Dr. Paul Schulz, professor and neurologist at UTHealth Houston.[[1]](https://www.doximity.com/newsfeed/7caa884a-c735-4670-a9ef-085aab35aa44/public)\n\n## Why it matters\nDementia affects millions, with cases projected to double by 2050; if links hold, these everyday interventions could delay onset for many older adults. For patients, it means discussing flu shots, managing blood pressure or cholesterol, and shingles vaccine with doctors might offer dual benefits, though not proven preventive. Watch for randomized trials to confirm causation beyond associations from claims data and cohorts.[[3]](https://www.uth.edu/news/story/risk-of-alzheimers-dementia-significantly-reduced-after-high-dose-influenza-vaccination-compared-to-the-standard-dose-study-finds)\n\n## FAQ\nQ: How much lower was dementia risk with flu vaccines in studies?\nA: Numerous studies showed vaccinated older adults had lower risk years later than unvaccinated; one reported up to 40% reduction. High-dose versions for ages 65+ linked to even lower Alzheimer's probability vs. standard dose per recent UTHealth research.[[1]](https://www.doximity.com/newsfeed/7caa884a-c735-4670-a9ef-085aab35aa44/public)[[2]](https://www.nytimes.com/2026/04/17/well/mind/medications-dementia-risk-decrease.html)\n\nQ: Why might these medications appear protective?\nA: They could directly benefit the brain or reflect healthier habits, like regular doctor visits and pill adherence. High-dose flu vaccine evidence suggests some direct vaccine effect, as all participants were vaccinated.[[2]](https://www.nytimes.com/2026/04/17/well/mind/medications-dementia-risk-decrease.html)\n\nQ: What other medications besides flu vaccine are mentioned?\nA: Blood pressure pills, cholesterol-lowering drugs like statins, shingles vaccine, anti-inflammatories, and diabetes drugs such as SGLT2s or GLP-1s show links in studies cited around the article.[[2]](https://www.nytimes.com/2026/04/17/well/mind/medications-dementia-risk-decrease.html)[[4]](https://www.reddit.com/r/fitover65/comments/1so5cls/6_common_medications_that_may_lower_your_dementia)\n\nQ: Is the evidence conclusive for lower dementia risk?\nA: No—mostly observational studies; scientists note challenges distinguishing correlation from causation, needing more research.[[2]](https://www.nytimes.com/2026/04/17/well/mind/medications-dementia-risk-decrease.html)","hashtags":["#dementia","#healthcare","#medicine","#vaccines","#alzheimers","#neurology"],"sources":[{"url":"https://www.doximity.com/newsfeed/7caa884a-c735-4670-a9ef-085aab35aa44/public","title":"Original article"},{"url":"https://www.nytimes.com/2026/04/17/well/mind/medications-dementia-risk-decrease.html","title":""},{"url":"https://www.uth.edu/news/story/risk-of-alzheimers-dementia-significantly-reduced-after-high-dose-influenza-vaccination-compared-to-the-standard-dose-study-finds","title":""},{"url":"https://www.reddit.com/r/fitover65/comments/1so5cls/6_common_medications_that_may_lower_your_dementia","title":""}],"viewCount":2,"publishedAt":"2026-04-23T10:30:36.545Z","createdAt":"2026-04-23T10:30:36.545Z","articlePublishedAt":"2026-04-17T00:00:00.000Z"}
