Sex hormone may prevent strokes in women

A new study has claimed that estrogen may prevent strokes in premature or early menopausal women.

Researchers at Mayo Clinic combined the results from a recent Mayo Clinic study with six other studies from across the world and found that estrogen is protective for stroke before age 50.

“We were very surprised because these results were unexpected,” Walter Rocca, the study author said.

“The old idea that estrogen is always a problem in the brain has to be corrected." Estrogen can be a problem in older women, he explains, but in younger women, estrogen may be important to protect the brain from strokes,” he said.

Rocca also said that the study has implications for women who experience premature (before 40) or early menopause (before 45) from natural causes or from ovary removal and that women in these groups should consider taking estrogen up to approximately age 50 to prevent stroke.

The study has been published in the journal Menopause.
