When patients with headaches go to the hospital, they first choose neurology because headaches are one of the most common conditions seen in neurology clinics. Some of the more common causes of headache include migraine, vasoneurotic headache, myalgic pain, cluster headache and so on. For patients with acute onset of headache, early consultation with neurology is recommended, especially for patients with nausea, vomiting or even fever. The main reason for consulting neurology is to differentiate secondary headache from cerebrovascular disease and central nervous system infection, because secondary headache often progresses rapidly and may worsen without regular treatment, so it is recommended that patients with headache consult neurology as soon as possible.
