A new study suggests hormone therapy may slow down the aging process for some women.

Researchers at Stanford University found those who were carriers of the Alzheimer's gene experienced significant aging at the cellular level. Over a two-year period, their cells aged the equivalent of 10 years. Women who were on hormone therapy did not experience that rapid aging.

Hormone therapy for postmenopausal women has been a controversial topic, ever since a 2002 study found the drugs could increase risk for heart problems.

Experts say this study helps them determine which women would benefit from hormone therapy, despite the risks.
