Long reproductive span, older age at menopause associated with lower dementia risk: Study

Apr 17, 2022

New Delhi, April 17 (ANI): Pregnancy, long reproductive span and older age at menopause are associated with a lower risk of dementia in women, according to a study. The results of the study were published in the journal, 'PLOS Medicine'. It suggested that reproductive and hormonal factors may be involved in dementia risk, but observed a similar association between the number of children and dementia risk in women and men, suggesting that the physical experience of childbearing may not account for risk variation. Dementia rates are increasing around the world, with some studies reporting a higher incidence in women than men, yet there is limited evidence-based on reproductive factors and the risk of dementia. Jessica Gong and colleagues used the data to examine the risk of all-cause dementia and reproductive factors in 273,240 women as well as the number of children in those women and in 228,965 men.
