Bitchiness in PMS Confirmed


A new study published by the Proceedings of the National Academy of Sciences shows that women's brains undergo dramatic changes five days before their menstrual cycles begin.

The researchers found that in the premenstrual time period, the women's frontal brain regions, which help control emotions, showed greater activity. The opposite was found in the days after the women's periods.
