Headaches are recommended for neurology, or in the case of Chinese hospitals, for encephalopathy. Headache is a common symptom in neurology, and more common is migraine. After the neurologist confirms the diagnosis, the patient can be given oral non-steroidal anti-inflammatory drugs and, if necessary, oral treprostinil, and will also be instructed to live a life that avoids the triggers of migraine. In neurology, headaches can also be caused by cerebrovascular diseases, such as transient ischemic attack, cerebral infarction, cerebral hemorrhage, and subarachnoid hemorrhage, which can be diagnosed by CT or MRI of the head, and require hospitalization if necessary. In neurology, headache can also be seen in intracranial space-occupying diseases, headache is mostly gradual and slow, after head CT or nuclear magnetic examination can also be diagnosed, treatment can be given to surgery or radiotherapy, chemotherapy and so on.
