It might be a double blessing for those women who are on estrogen therapy before the age of 65. Recent research has shown a protective element of reduction in the risk of Alzheimer's disease or dementia.
The study showed that women who took any form of estrogen hormone therapy before the age of 65 cut their risk of dementia by 50%, as compared to women who were not on hormone therapy before the age of 65.
This study was part of the Women's Health Initiative Memory, and holds a distinction of being the most exhaustive study in the US to look at prevention measures in post menopausal women; the study analyzed the usage of hormone therapy in 7,153 healthy women aged 65-79 . Their cognitive health levels were tracked for an average of five years.
"We found that it didn't matter how old the woman was when she started hormone therapy, how long or recently she took it or what kind of prior therapy she used," said study author Victor W. Henderson, MD, of Stanford University.
"Further studies are needed to support these findings and learn more about how hormone therapy affects the long-term cognitive health of women who begin use before age 65," said Henderson.
