Estrogen Later May Shield Brain from Dementia | Science News

New research reveals women who started estrogen-only hormone therapy around age seventy showed a 39% lower risk of dementia and 35% less brain plaque buildup—key Alzheimer’s markers—compared to peers who didn’t use it. Based on autopsy data from over 21,000 women, the study suggests a potential protective effect, though it’s not proof of prevention. Crucially, this contrasts with today’s guidelines, which recommend starting therapy earlier and stopping before age sixty. While the exact mechanism remains unclear, these findings offer a compelling clue in the fight against neurodegeneration—and remind us that timing matters when it comes to brain health.
