Estrogen Reversal

A study says long-term hormone therapy, which already has been shown to have physical health risks, also does not help women's mental states.

The new study says H-R-T does not help memory, sleep or the sex lives of older women. The study says the therapy gives a little help for hot flashes and night sweats, but only for about a year.

The results are another blow against H-R-T, which has been a commonly used treatment for miseries of menopause and aging. Researchers earlier found H-R-T slightly increases the chance of heart attacks, strokes and breast cancer. The lead researcher says the average woman won't improve quality of life by taking hormone therapy. She says women would be better off with exercise.

The researcher is at Baylor College of Medicine. The study was released early by the New England Journal of Medicine.
