The study was published in Biological Psychiatry, revealing that mood instability before menstruation is related to a response from brain cells called receptors GABA.
The researchers carried out the study by scanning the brains of women with the premenstrual dysphoric disorder (PMDD) with the symptoms of PMDD which is like the Premenstrual syndrome (SPM), only more serious.
PET scan showed the glucose metabolism required to identify the activity in the brain and the cause of the emotional changes before menstruation turned out not to be motivated by hormonesInstead, the analysis actually showed increased activity in the cerebellum of women with PMDD and the greater the increase in activity, the worse the condition for emotional changes.
One of the functions of the cell GABA is to limit activities related to stress and anxiety, that in women with premenstrual dysphoric syndrome the progesterone changes the shape of GABA receptors in the cerebellum and it is this change before menstruation that makes GABA cells difficult manage stress and anxiety.
