Hormone linked to women's mood swings before period

The study focused on the relationship between elevated levels of the hormone progesterone and mood changes in women. The results showed that increased levels of this hormone during different phases of the menstrual cycle lead to difficulties in distinguishing between various emotional situations and weakened emotional regulation, especially when the frontal cortex levels are unable to easily differentiate between emotional states. It was found that women with high progesterone levels exhibit similar patterns of activity in brain regions involved in behavior and emotion regulation, which may contribute to mood swings. Progesterone levels typically rise after ovulation and persist through the luteal phase before the cycle ends. This increase is associated with heightened threat sensitivity and difficulty controlling emotions. However, researchers warn against considering this hormone as permanently causing mood problems, emphasizing that hormonal processes are part of a more complex picture.
