Along with dwelling longer, the explanation for the upper feminine prevalence is considered associated to the results of menopause and the affect of the genetic danger issue APOE4 which is bigger in ladies.

“We wished to seek out out whether or not HRT might stop cognitive decline in APOE4 carriers in danger.”

The analysis workforce studied information from 1,178 ladies who took half within the European Initiative for the Prevention of Alzheimer’s Illness Dementia – which was set as much as examine individuals’ mind well being over time.
