Many women who are about to experience menstruation often become irritable which causes discomfort for people around her.

The mystery of why women easily gets upset and anxious before their period has always been a big question. Researchers from the University of California, Los Angeles, also conducted a study to find answers to such emotional turmoil.

In the study which was published in ‘Biological Psychiatry’ journal, researchers revealed that the instability of mood before menstruation is related to the response of cells of the brain called GABA receptors.

Andrea Rapkin, one of the researchers, said that the study was carried out by scanning the brains of women with premenstrual dysphoric disorder (PMDD). PMDD symptoms is like premenstrual syndrome (PMS), only it is more severe.

The scanning with PET scan will show the glucose metabolism which is required to identify the activity in the brain.

The cause of emotional changes before menstruation turned out not to be caused by hormones. Scan results actually showed an increase in activity in the cerebellum in women with PMDD. The higher the increase in activity, the worse the emotion condition changes.

One function of the GABA cell is to limit activities related to stress and anxiety. In women with PMDD, progesterone will change the shape of GABA receptors in the cerebellum. This changes in shape before the menstrual period makes GABA cells difficult to control stress and anxiety.

Suzanne Abraham, a gynecologist at the Royal North Shore Hospital, Sydney, Australia, said that although it is carried out on women with PMDD, this study adequately represent the condition of women in general. For your information, women with PMDD are only about percent, according to New Scientist. — Courtesy of Medicmagic

Interesting to hear this information coming out of Brunei and not the U.S. Endocrine system functioning and balance does begin in the brain – GABA is one of the neurotransmitters involved in addictive behaviors….and for some women PMS and anger is addictive.
