Unclear: Pmdd is thought to be related to the drop in estrogen that occurs at the end of the menstrual cycle. These estrogen levels tend not to drop as much during the first few years when females start cycling. As time goes on, the drop can become more significant and symptoms develop. We are not aware of any other factors that increase risk.
