What were the results of the Women's Health Initiative Memory Study?
The Women's Health Initiative Memory Study found that taking conjugated equine estrogens resulted in an increased incidence of probable dementia and mild cognitive impairment in postmenopausal women compared to those not taking the hormones. The study also found that taking conjugated equine estrogens was associated with improved global cognitive function in postmenopausal women. These results were published in the JAMA journal in 2003 and 2004.
