Researchers have found a significant connection between vaccination and lower rates of dementia.
Protection Through Vaccination – Or Not?
A study published in June 2026 in the “Annals of Internal Medicine” evaluated data from over 500,000 participants. The findings revealed that vaccination with Shingrix reduced the risk of dementia by 24 percent. Researchers suggest that the reduction of inflammatory processes plays a key role in this protective effect.
However, the scientific community remains divided. A concurrent replication study from England found no significant effect. Experts are therefore calling for further research to elucidate the exact mechanisms at play.
Diabetes Medications as Dementia Brake
Other substances also exhibit surprising potential. Data from the National Institutes of Health (NIH) suggest that SGLT2 inhibitors could lower the Alzheimer’s risk by 43 percent, while GLP-1 agonists could reduce the risk by 33 percent. Both classes of drugs are primarily used in diabetes therapy.
Furthermore, since June 2026, two new antibody therapies, Lecanemab and Donanemab, have become available, targeting amyloid plaques in the brain. In Germany, approximately 120,000 out of 1.2 million Alzheimer’s patients are eligible for these treatments. The economic significance is immense, with annual costs for dementia-related conditions exceeding €80 billion.
AI Detects Alzheimer’s Years Before Onset
The latest study from Brown University shows that the Shingrix vaccination can lower dementia risk by 24 percent. What other measures are proven to protect—from Mediterranean diets to hearing aids—are detailed in the current report. Request your free report now
Early diagnosis is making significant strides. AI-assisted retinal scans can identify Alzheimer’s risk up to 8.55 years before the first symptoms appear. Market researchers forecast growth in this sector to reach $9.4 billion by 2033.
Blood tests are also becoming more precise; the determination of the protein pTau217 now achieves over 90 percent accuracy.
Lifestyle as a Risk Factor
In addition to medication, daily life plays a crucial role. Long-term studies from the Karolinska Institute indicate that an anti-inflammatory Mediterranean diet can lower the risk by 30 percent. The use of hearing aids correlates with a 23 percent reduction in risk.
A U.S. study involving over 90,000 participants conducted in July 2026 revealed an unexpected correlation: those who skip dental visits for financial reasons have an increased risk of dementia and cardiovascular diseases.

Not everything that sounds good is effective. High-dose omega-3 (DHA) showed no cognitive improvements in a two-year study. Worse yet, a June 2026 study found that glucosamine supplements increased the dementia risk by 25 percent.
Certain medications are also under scrutiny. Anticholinergics and proton-pump inhibitors are linked to increased risks of 54 and 44 percent, respectively.
