Severe PMS, also known as PMDS, affects not only the body before menstruation. Now, research from Umeå University shows that it can also be seen in the brain, which can be an explanation for the severe mood swings many women experience, reports Sveriges Radio P4 Västerbotten.
Researchers at Umeå University have made the discovery by studying brain activity using a magnet camera.
One can say that the brain's activity pattern is noticeably affected during the premenstrual phase and it reflects well what the women themselves experience, says doctoral student Louise Stiernman, who wrote the dissertation, to the radio.
Around 60,000 women in Sweden suffer from premenstrual dysphoric syndrome, PMDS.
