WHAT IS THE INCREASED RISK FOR WOMEN TAKING ESTROGEN-ALONE?
In the WHIMS Estrogen-Alone study we found that a woman was more likely to develop dementia if she had been taking active estrogen pills. However, the number of women who actually did develop dementia was small–37 out of 10,000 women taking estrogen–alone each year, compared to 25 out of 10,000 women taking placebo each year, or a difference of 12 women. While this difference is important, the number of individual women who were affected was small.
