Researchers found that older adults with a specific genetic profile had a 70% lower relative risk of dementia when taking low-dose aspirin, even though previous studies found no overall protective effect. The discovery suggests that genetics could help explain why some people benefit while others do not.

An analysis carried out in groups of elderly with genetic subdivisions identified beneficial effects for the reduction of up to three and a half times the risk of dementia with the use of low dose aspirin in people who have a high number of platelets genetically. On the other hand, the study led by scientists at Monash University, Australia, pointed out that this same portion had a double higher risk of severe bleeding. The interaction of aspiri…

A team of researchers from Monash University, Australia, identified that low doses of aspirin reduced the relative risk of dementia in elderly people with genetic characteristics related to the highest platelet count by about 70%. The results were published in 2026 in the scientific journal Alzheimer's & Dementia and are based on data from 13,541 volunteers.
