Video head impulse findings in the ictal period of vestibular migraine
Vestibular migraine (VM) manifests as central or peripheral vestibular dysfunction during vertigo attacks . However, no studies have reported the findings of video head impulse tests (vHIT) during the ictal period of VM. Herein, we report unique findings of vHIT in a patient with VM during a vertigo attack.
A 40-year-old man presented with positional vertigo without auditory symptoms. Sitting up from the supine position, but not vice versa, aggravated his vertigo.

Video Legend Video recording of video head impulse tests during stimulation of the right anterior canal and left posterior canal.

During the follow-up period, these patterns gradually disappeared. (MP4 8640 KB)
