[An analysis of clinical features of 226 vestibular migraine patients].

OBJECTIVE

To explore the clinical characteristics of vestibular migraine in patients from the clinic and ward of the neurological department in comprehensive hospitals.

METHODS

A total of 226 patients diagnosed as vestibular migraine were enrolled in the study. Clinical data were collected and analyzed, including the medical history, clinical symptoms and signs, as well as the result of diagnostic examinations.

RESULTS

The mean age of the patients at the visit was 51.7 years old, with the male to female ratio of 1: 1.48. The occurrence of vertigo and migraine varied in order, with 53.1% (120/226) patients presented migraine several years before vertigo. The duration time of vertigo ranged from seconds to days, with 1.8% (4/226) patients presented no headache during the whole course. Several punctate long T(2) or high FLARE (fluid attented inversion recovery) signals scattered at the centrum ovale.

CONCLUSIONS

Vestibular migraine has complex mechanism and presents multiple clinical manifestations with certain regularities of the onset. Differential diagnosis should be made from the similar diseases.
