Daily aspirin did not prevent dementia in older adults overall, but people with one genetic profile tied to higher platelet counts had markedly lower dementia rates while taking it, according to a reanalysis of the ASPREE trial in Alzheimer's & Dementia. In that group, 1% of aspirin users developed dementia, compared with 3.3% of those on placebo.
