Objective oculomotor, vestibular, reaction time, and cognitive signatures of vestibular migraine

1

Vestibular migraine is a prevalent yet often underdiagnosed cause of vertigo, with diagnosis primarily based on clinical history.
2

Objective OVRT-C testing identified significant abnormalities in oculomotor, vestibular, and cognitive functions in vestibular migraine patients.
3

A substantial percentage of vestibular migraine patients showed abnormal performance in metrics like saccades and gaze stability compared to healthy controls.
4

Logistic regression analyses revealed six OVRT-C metrics as strong indicators of vestibular migraine, demonstrating high sensitivity and specificity.
5

The study supports the use of eye-tracking–based assessments as valuable tools for characterizing vestibular migraine and calls for further validation.
