Migraine is one of the most common types of primary headache in clinical practice and can cause great suffering to patients over a long period of time and frequently. Migraines bring not only head pain, but also psychological and mental torment. Some patients are affected by migraine for a long time, their personalities change, their psyches become distorted, some cause depression, and even finally choose to commit suicide. So how is this neuropathic migraine caused? Migraine is said by some to be neurological and by others to be vascular. In fact, according to scientific research, the occurrence of migraine is related to both nerves and blood vessels. It is said that the blood vessels and nerves on the scalp of ordinary people are in a companion relationship and do not interfere with each other; while migraine patients have abnormal compression or entanglement of the blood vessels on the scalp to the related nerves due to various reasons, and the concentration of pain-causing neurotransmitters in the blood changes abnormally due to various reasons such as emotional fluctuations and endocrine changes, and the blood vessels in the compressed segment cause stimulation to the nerves, thus causing headache attacks. For the treatment of migraine, most local hospitals tend to adopt the conservative therapy of internal medicine, which is possible for mild migraine and can relieve the disease to a certain extent. If the symptoms of mild migraine are mild and the attacks are infrequent, there is no need to make a big fuss if it does not affect the life and work much. However, in the case of intractable migraine, the pain is so severe and frequent that it seriously affects the normal life and work, and it is difficult for medical treatment to be effective, it is necessary to start early treatment from the cause. Microvascular decompression is such an effective surgical treatment, which can reach the lesion and release the compression between the blood vessels and nerves to solve the problem and treat migraine.
