Migraine is often seen in many people around us, so what is the cause of this disease with high incidence? According to the relevant data, the cause of migraine is still unclear, but from the results of clinical research, most experts agree with the neurovascular theory. In addition, experts have also found that migraine is inextricably linked to genetic factors and living environment. The cause of migraine: 1.Neurovascular theory After long-term research and summary of migraine patients, experts found that the blood vessels and nerves on the scalp of normal people are in a companion relationship and do not compress each other, while the blood vessels and nerves of migraine patients cause abnormal compression or entanglement of the nerves due to various reasons, which causes headache under the influence of certain factors. Some scholars have done a survey on migraine patients with family history of migraine, and found that if one person in a family has suffered from migraine, the chance of their related first-degree relatives is high. Therefore, patients should first ask their family members about their medical history after symptoms appear, and then do detailed examination and actively seek medical treatment. 3.Bad habits of life and factors Along with the fast-paced life, many young people have pressure due to work, mortgage and car loan, and often stay up late and work overtime, sometimes they do not rest well at night and feel tired the next day, which leads to headache symptoms; also patients usually like to eat cheese, chocolate, drink coffee, red wine and lemon juice, these bad eating habits will also greatly increase the chance of headache, so migraine patients Therefore, migraine patients should pay more attention to their dietary structure and get enough sleep. For the neurovascular theory, we have carried out microvascular decompression for migraine and achieved good results. Microvascular decompression is a microscopic procedure to find the pressure point between the nerve and the blood vessel at the lesion, isolate the responsible blood vessel, and protect the nerve. Microvascular decompression is a minimally invasive procedure that does not require craniotomy, the incision is only 3-5 cm, and the postoperative recovery is quick and aesthetically unaffected.
