"Early Menstruation Linked to Higher Dementia Risk"

A study suggests that women who start menstruating early and experience later menopause may have a reduced risk of developing dementia later in life, possibly due to prolonged estrogen exposure. The research, conducted on over 270,000 female participants, found a 12% lower dementia risk for those who began menstruating at or before 12 years old and a 24% lower risk for those who experienced menopause in their 50s. While more research is needed to confirm these findings, the study adds to the evidence for hormone replacement therapy as a potential protective method against dementia.
