Estrogen may increase dementia risk

Research has shown that estrogen increases older women's risk of
developing dementia and cognitive decline. How estrogen does that,
though, has been a matter of debate. But a study published online in
Neurology suggests that the hormone may do this by shrinking women's
brains

Once again we hear bad results from "estrogen therapy" but which estrogen was used? Most papers that I am familiar with are about synthetic hormones not natural estradiol because most menopausal HRT is synthetic i.e. Premarin.

Estrogen shrinks women's brains?  Starting when?  Puberty?  Let's hope the misogynists and wife-beaters never hear about this.

Well, at least you won't know .
