Ultra low-dose estrogen shown safe for post-menopausal women

A study led by researchers at the San Francisco VA Medical Center has shown that extremely low doses of estrogen had no ill effects on the cognitive abilities or general health of older women over the course of two years.

"This is exciting. It shows that women can take estrogen safely," observes lead author Kristine Yaffe, MD, chief of geriatric psychiatry at SFVAMC and associate professor of psychiatry, neurology, and epidemiology at the University of California, San Francisco.

In 2004, study results from the Women's Health Initiative (WHI), a nationwide longitudinal study sponsored by the National Institutes of Health, indicated that estrogen was associated with an increased risk of dementia among women 65 and older, as well as with an increased risk of heart attack and stroke.

"Those results raised a lot of doubts about whether women should be taking estrogen at all," Yaffe notes.

The current study, published in the July 2006 issue of Archives of Neurology, looked specifically at the potential effects of estrogen on cognitive abilities and quality of life. A group of 417 post-menopausal women aged 60 to 80 were randomly assigned to receive a daily .014 milligram dose of either estradiol, a form of estrogen, or a placebo through a skin patch for two years. The women were given a battery of standardized cognitive tests and a test of health-related quality of life at the beginning of the study, after one year, and after two years.

At the end of the study, there was no difference between the two groups in either cognitive abilities or health-related quality of life.

"The results are very reassuring, because it suggests that women can use this patch without harm for two years," says Yaffe. "It would benefit their bones and might have a beneficial effect in terms of hot flashes."

A related study of the same group of women showed a significant increase in bone density, without adverse health effects, in th
