title: [Clinical characteristics of 100 vestibular migraine cases].
abstract: OBJECTIVE
  To analyze the characteristics of vestibular migraine (VM), in order to understand the auditory and vestibular function.
  
  
  METHODS
  One hundred cases of confirmed or suspected VM patients were observed. Routine examination including pure tone test, vestibular dual temperature test and vestibular evoked myogenic potential(VEMP) and video head impulse test(v-HIT) Were conducted.
  
  
  RESULTS
  The incidence of male and female was about 1.00 : 2. 57. The average age of onset was 47 years, of which the youngest was 19 years old, and the oldest was 74 years old. Ninty-three cases of patients presented with vestibular sensitive performance, including photophobia, phonophobia,or motion sensitive. Fourty-two patients had migraine at the onset of the disease. Thirty-four patients had cochiear symptoms, including tinnitus, ear fullness, or epicophosis. In seventeen cases of fatigue, tension or poor sleep can cause vertigo. Nine patients had low blood pressure, 7 patients presented with hypertension. Two cases of vertigo were closely related to the change of position, and 1 case had visual aura. In the experiment, 94 patients had undergone VEMP test,with 44 cases of abnormal VEMP value. Seventy-nine patients had been examined v-HIT,of whom 2 patients were abnormal (both of which were reduced). Pure tone audiometry was abnormal in 35 cases. Five cases of patients showed abnormal vestibular-double temperature test.
  
  
  CONCLUSIONS
  Vestibular migraine is more prone to female, with young middle age, and can be accompanied by cochlear symptoms. Vestibular function tests (low frequency and high frequency) are normal.
