This contains getting common train, collaborating in leisure and academic actions, not smoking or utilizing alcohol, and sustaining a wholesome weight, she mentioned.
For the examine, researchers in contrast age at menopause and dementia prognosis amongst 153,291 girls (common age: 60) who had been a part of the UK Biobank, a big database of genetic and well being data on folks dwelling in the UK.

Whereas girls who entered menopause early had been at larger danger of dementia, those that entered menopause at age 52 or later had related charges of dementia as girls who began menopause at age 50 or 51, the examine confirmed.
The brand new findings held after researchers accounted for different elements that will increase dementia danger, together with age finally examination, race, schooling, cigarette and alcohol use, physique fats, coronary heart illness, diabetes, earnings and leisure and bodily actions. The examine didn’t embrace data on whether or not girls had a household historical past of dementia or if girls entered menopause early for pure or medical causes, which may have an effect on the findings.
The findings had been introduced Tuesday at a gathering of the American Coronary heart Affiliation held in Chicago and on-line. Analysis introduced at medical conferences is usually thought of preliminary till revealed in a peer-reviewed journal.
These findings are per different research exhibiting a higher danger of dementia amongst girls with untimely or early menopause, mentioned Dr. Stephanie Faubion, medical director of the North American Menopause Society and director of the Mayo Clinic Heart for Girls’s Well being.
“The early lack of estrogen is linked with an elevated danger of a number of hostile long-term well being outcomes, and dementia is only one of them,” mentioned Faubion. Others embrace coronary heart illness, brittle bone illness, osteoporosis, temper problems, sexual dysfunction and early dying.

For years, hormone replacement therapy was broadly prescribed to deal with signs of menopause and decrease danger for coronary heart illness, osteoporosis and dementia. This all modified when the landmark Girls’s Well being Initiative examine confirmed that taking estrogen and progestin after menopause might improve girls’s danger for stroke, coronary heart illness, blood clots and breast most cancers. (Estrogen helps with menopause signs like scorching flashes and vaginal dryness, and progestin is added to guard towards uterine most cancers in girls who nonetheless have a uterus.)
As we speak, hormone substitute remedy could also be prescribed within the lowest dose for the shortest period of time to maximise advantages and reduce potential dangers.
