Key clinical point: Loudness discomfort levels and temporal auditory processing may help diagnosis patients with vestibular migraine (VM).
Major finding: VM patients experienced response latencies with longer frequencies and a lower noise tolerance, compared with patients without migraine. The statistically significant findings showed that “the frequency following response latencies were significantly longer in the patients with vestibular migraine than in the control group, suggesting altered pure tone temporal processing, which may also affect the processing of complex sounds,” noted the investigators. “The lower discomfort thresholds suggest the presence of mild hyperacusis, in concordance with other previous studies.”
Study details: Fifty-four women were split up into two groups: 29 women with VM and 25 healthy women without migraine.
Disclosures: The authors reported having no conflicts of interest.
