The causes of menstrual migraine are as follows: First, it is caused by the dysfunction of the endocrine system, during women’s menstrual period, the hormone level in the body will have a large change. The amount of estrogen, sex hormone, progesterone and luteinizing hormone, etc., some of these hormones will have a large rise and some will have a large fall, and the large fall can cause a temporary dysfunction of the sensory function of the cerebral cortex, or due to the metabolic substances of hormones in the body, it can also stimulate the central nervous system, leading to migraine in women. Secondly, it may be caused by emotions. Some women may have more negative emotions during menstruation due to emotional fluctuations, easy tension, anxiety or indifference, and negative emotions can also indirectly affect the function of the cerebral cortex through neurohumoral regulation, resulting in migraine headaches.
