Abstract
The objective is to analyze the vestibular system by vestibular evoked myogenic potential VEMP in 30 female patients with migraine and balance problem in a controlled study Thirty female patients with migraine and vestibular problems were enrolled in the study 2009–2012 Fifteen agematched healthy subjects were selected as the controls Air conduction cervical VEMP was used Toneburst sound stimuli of 95 dB nHL with rarefaction polarity 5 Hz stimulus repetition rate 1 ms rise/fall time and 2 ms plateau time were delivered at 500 Hz 200 sweeps were averaged Myogenic responses were amplified and bandpass filtered 800–10 Hz The latency and the amplitude of p1 and n1 waves and interpeak amplitude and latency differences were measured Results were given as mean and SDs Interaural p1 and n1 amplitude greater than 30 asymmetry was accepted as abnormal VEMP results were compared with controls The Oneway ANOVA test was used Statistical significance was set at P 005 VEMP responses were elicited in all controls and the patients Comparative analysis of p1 amplitude between the patients and the controls was statistically significant P = 0010 P1n1 interaural amplitude difference was greater than 30 in 4 patients 134 No statistically significant difference was found when comparing latency of all wave forms between the patients and healthy controls P 005 VEMP is an useful tool to test the vestibular system in patients with migraine and balance problem at the very early period Clinicians should always consider migraine in patients with vertigo
