In an effort to better understand the women, scientists have begun studying the womans brain during PMS and her Period.
Nature.com: “Help may soon be on its way for women who live with the pain of premenstrual syndrome (PMS), and for those who live with them. Researchers have begun to investigate what happens in the brain as a woman’s hormones surge before her period.
So far, they say, the results tentatively indicate that a boost in brain activity in an emotional centre of the brain might help to keep some women more emotionally stable, even as their hormones go on a roller-coaster ride.
Despite huge amounts of interest in PMS and the drugs that might combat it, surprisingly little research has looked at how the brain behaves during this turbulent time, says David Silbersweig, a neurologist at Cornell University’s Weill Medical College in New York City. He notes that among women of reproductive age, roughly 75% report mood swings or physical discomfort during their premenstrual phase.
Silbersweig and his colleagues recruited 12 women who experience consistently steady moods during their cycle, to create a baseline for future studies of women with huge mood swings. The researchers conducted tests and brain scans twice during the subjects’ monthly cycles: once during the premenstrual phase and again about ten days later.”
