High prevalence of incidental brain findings in primary dysmenorrhoea

摘要

BackgroundPrimary dysmenorrhoea (PDM) is inexorably common. PDM women suffer from cramping pain in the lower abdomen that starts with menstruation and lasts for 24-72h. Up to 90% of adolescent girls and more than 50% of menstruating women worldwide report suffering from it. Ten to 20% of PDM women describe their suffering as severe and distressing. However, nothing is known regarding the association of PDM with possible brain anomalies or abnormalities.
