Migraine headaches need to be determined by combining the results of medical history, symptoms, and examination to determine whether it is a brain tumor or not. Migraine headache should be understood as lateral headache, and migraine headache is a kind of vascular headache, which is fundamentally different from migraine headache. 1. Medical history: patients with brain tumor often have the history of viral infection, epilepsy, and may also be related to frequent exposure to electromagnetic radiation, use of hair dyes, excessive intake of nitrosamines in diet and other factors. 2. Symptoms: The typical symptom of brain tumor is increased intracranial pressure, which can be manifested as headache, vomiting, optic nerve papillary edema. Headache can be aggravated in the morning, cough, stool. Therefore, if patients with migraine headache also have the above symptoms, brain tumor should be highly suspected. In addition, sensory disorder and ataxia may also appear in the early stage of the disease. 3. Examination: patients need to cooperate with doctors to do head CT and MRI scanning examination, which can clarify the location, size and anatomical relationship with surrounding structures of the tumor. Cerebral angiography can understand the blood supply in the tumor and the relationship with the important blood vessels in the skull. All of them help in the diagnosis of brain tumor. In addition to this, migraine headaches can also be caused by diseases such as cluster headache and primary migraine. It is recommended that patients with migraine headache should go to the hospital, complete the relevant examination, clarify the cause and then actively treat it.
