New Delhi, June 6
Women with early onset of periods, and later menopause -- which means a longer reproductive span -- can have a healthier brain ageing in life, according to a study.
The study showed how a woman’s reproductive years may shape brain health later in life and also reduce the risk of dementia.
It also suggested the role of oestradiol (or the lack thereof) in the development of dementia.
Oestradiol levels rise at puberty, remain high during most of a woman’s reproductive life, and then decline sharply around menopause. This drop in oestradiol has been linked to an increased risk of dementia and other age-related brain conditions.
“These findings support the idea that oestradiol -- the most potent and prevalent form of oestrogen during a woman’s reproductive years -- may help protect the brain as it ages,” said lead researcher Eileen Lueders, Associate Professor from the University of Auckland’s School of Psychology.
The research may point toward the potential for health interventions such as hormone treatment in the years leading up to menopause and immediately afterward to combat an increased risk of Alzheimer’s for some women.
