Headache and vertigo are the most common clinical symptoms. Headache generally refers to pain in the upper part of the skull (above the line connecting the arch of the eyebrows, the upper part of the auricle, and the external occipital ridge), and pain in the face and jaw is not part of headache. Migraine is a disorder that manifests as chronic episodic headache and is the most common primary headache. Vertigo is a sensation with environmental or self-induced motion hallucinations, including spinning, tipping, swaying, etc. The usual sensation of light-headedness and dizziness are not part of vertigo. The prevalence of migraine is high, with studies showing that the prevalence of migraine in adults ranges from 7.7% to 18.7%, with more women than men, with 1% to 19% in adult men and 3% to 29% in adult women. Migraine is related to genetic, endocrine, psychiatric and dietary factors, and is a polygenic, multifactorial disease in which genetic factors interact with environmental factors. The disease name migraine originated from migraine, but not all migraineurs have unilateral headache, and unilateral headache only accounts for 60%. The main manifestation is unilateral or bilateral pulsating pain in the frontal, temporal or half of the head, mostly moderate to severe pain with nausea, vomiting, photophobia, photophobia and phonophobia, which can be relieved by itself and mostly lasts from 4 to 72 hours. Some patients may have symptoms such as flashing lights in front of the eyes, dark spots and visual field defects before the headache, which we call aura symptoms. Compared with the two, peripheral vertigo is more acute and severe, more often accompanied by cochlear symptoms such as tinnitus and hearing loss, and autonomic symptoms such as nausea and vomiting, and lasts for a shorter period of time, mostly lasting for seconds, minutes or days. The duration of vertigo is longer, lasting several days, months or years. In clinical practice we have observed that many patients with migraine have vertigo or dizziness, and it is common to see patients with a history of migraine who present with vertigo in vertigo clinics. selby and Lance et al. in 1960 analyzed 217 migraine patients in a neurological treatment center and found that 72 (33%) had vertigo; another group of 131 migraine patients 94 (72%) had Neuhauser in 2000 analyzed 200 patients from a dizziness clinic and 200 patients from a migraine clinic. found a significantly higher incidence of migraine in the group of dizzy patients according to the HIS migraine diagnostic criteria, about 38% compared to the control group. In addition, it was found that for migraine patients with a history of vertigo, sumatriptan, a medication for migraine, was effective not only for headache but also for improving vertigo. Therefore, it is recommended that migraine patients with vertigo symptoms undergo vestibular function tests to determine the presence of abnormal vestibular function, and some studies have now found a high positive rate of vestibular function tests even in patients without vertigo complaints. Migraine and vertigo are relatively common in clinical practice and there is a relationship between them, but there is no evidence to prove whether there is a causal relationship and a lot of work needs to be done by medical practitioners to further elucidate.
