"The cognitive function of women is not affected by hormonal changes by physiology" Research results will be announced

Women who are experiencing menstrual stomachache or headache say that attention decreasesResearch result of 2014The content that menstruation affects the performance of women's brain has been announced several times so far. However, the latest research conducted by Professor Brigitte Leeners and colleagues working at the University of Zurich in Switzerland asserts that "cognitive function of women is not affected by changes in hormonal levels due to physiology".

The female physiological cycle is generally a 28 day cycle in which follicular phase, ovulation phase, luteal phase, and physiological phase exist, and the luteinizing hormoneProgesteroneOr follicle hormoneestrogenSecretion will increase or decrease. In a study done so far, hormones such as estrogen and progesteroneInfluence women's cognitive functionAlthough the investigation result was published, the result that the latest research shows that "the secretion of estrogen and progesterone does not affect women's cognitive function" was announced. Professor Brigitte Leeners who conducted the research pointed out that the research conducted in the past has had few samples and the possibility that a methodological bias has occurred. In other words, because it was a small scale study, I believe that the relationship between cognitive function and hormones should have been shown.

A survey by the research team of Leeners et al. Selected 88 subjects from 18 to 80 years of age and eventually the relationship between hormone levels and cognitive function was measured in the physiological cycle of 68 women over 2 months It was. During the period, researchers measured hormone levels such as estrogen · progesterone · testosterone, while at the same time, using touch screen devices, point simultaneously to multiple subjects "Split attention"Working Memory of Visual and Space", remembering the shape, color and movement of things, cognitive bias, judgment mistake, etc. were tested.

As a result of the investigation, it was confirmed that the level of progesterone and testosterone influenced the results of the test at the first month, but this effect was not seen at the second month. For this reason Professor Leeners explains, "When completing the first test, women will learn what the test is like, so the second time we will improve the performance," said " I believe that women's cognitive functions work clearly regardless of the level change. " In the past experiments, "the second month performance" could not be examined, so it seems there was a part that was not obvious.

Also, in the research, we repeatedly analyzed the performance of each subject and compared the performances of subjects, but no difference was seen.

On the other hand, although the subject of this research was more subjects than past studies, it is still less than 100 people, the research teamPremenstrual dysphoric disorderBe careful that you are not investigating about it, and that you are only testing three functions of the brain. The cognitive function in general has not been fully examined, and the relationship between hormone levels and cognitive functions is not completely denied, so further research is expected in the future.
