▪Biomarker tests collected during life showed that women using estrogen-only hormone therapy had amyloid biomarker levels in blood and spinal fluid consistent with less amyloid accumulating in the brain.
▪Among study participants whose brains were examined after death, 18% of estrogen-only hormone therapy users showed no signs of Alzheimer's disease at autopsy, compared to 10% of non-users.
▪After accounting for factors like age, education, genetics, race, and hypertension, estrogen-only hormone therapy use was associated with 35% lower odds of showing signs of Alzheimer's disease at autopsy.
