This great study by Young et al (“Clinical, oculographic and vestibular test characteristics of vestibular migraine.” pub. Cephalalgia. 2021) characterises the history, vestibular tests, ictal and interictal nystagmus in vestibular migraine. The study concludes with three “key findings:
Most patients with vestibular migraine show spontaneous nystagmus during vertigo attacks.
A small portion of patients with vestibular migraine show asymmetric caloric test results.
Patients with vestibular migraine typically have normal lateral video head impulse test results, interictally.”
