It is a functional headache without any organic lesions in the brain, and no abnormal findings can be found during cranial CT or MRI, and there is no vascular stenosis or occlusion during angiography. The cause of the headache is not completely clear, but some studies suggest that the attack may be related to vasoconstriction and dilation dysfunction, abnormal secretion of neurotransmitters such as 5-hydroxytryptamine and trigeminal nerve dysfunction, and blowing wind is a common trigger. It can be triggered by many kinds of factors, besides blowing wind, drinking alcohol, staying up late, cold, fever, bad mood, and some foods such as chocolate, coffee, strong tea, cheese products, chicken liver, cured meat, etc. Patients should try to avoid the triggers to reduce the attacks, and women with endocrine disorders during menstruation are more likely to have these headaches.
