Estrogen is of no benefit

Dear Dr. Roach: My 78-year-old mother has taken compounded estrogen since menopause. She swears that it has kept her from getting Alzheimer’s disease and other brain diseases.

I am 54 and have been in menopause for about a year. I’ve tried hormone replacement therapy, but I’ve had weight gain and other side effects. Eventually I decided that the hot flashes weren’t so bad after all, and went off the pills altogether.

So far, I’m managing my symptoms just fine. But my mom thinks I should go back on the estrogen because of the long-term brain benefits.

Are the long-term brain benefits of estrogen clear enough for me to give the pills another chance? And if so, does it matter if the estrogen is compounded? — M.S.

Answer: For many years, physicians recommended estrogen (plus progesterone for women who had not had a hysterectomy) because of benefits seen in reduced heart disease risk, and some studies also showed reduced risk of developing Alzheimer’s disease. However, that changed when good studies were published showing that there was more harm than benefit overall, and now estrogen generally is used only for symptoms of menopause, especially the “hot flashes” caused by abnormal regulation of blood vessels.

Those same studies on heart disease also have provided some data on the risk of dementia in women taking estrogen compared with those who do not. Some studies showed a little benefit; others showed none, or even some harm. The largest, a subset of the Women’s Health Study, showed no benefit and a trend toward harm from estrogen.

I do not recommend estrogen to prevent Alzheimer’s. The most effective interventions to reduce risk of dementia remain regular physical exercise and maintaining high levels of social contact and cognitive function (such as games, puzzles, etc.).
