High Estrogen Levels, Diabetes, & Dementia Risk
Study of older women found having more of hormone from fat tissue after age 65 unwise
It's referred to as the "critical window of estrogen therapy," said Carr.
But this study suggests that once that "critical window" closes, a woman with elevated hormone levels may be at a higher risk for dementia, said Carr. "And it also suggests that the combination of diabetes and high estrogen has an even greater effect on dementia risk."
Does the research suggest that older women who take hormone replacement therapy stop -- especially those with diabetes?
Scarabin said the study is not a hormone study -- the women involved in the research were not taking estrogen -- and the results do not suggest women who take estrogen go off of their medication.
Gandy said, "Before we make recommendations, we need to do clinical trials. We'd need to see if women on estrogen at age 'X' versus a same-age placebo group who did not get estrogen had the same effect."
Scarabin added that women with both diabetes and elevated estrogen levels would be a good "target for future prevention studies."
