Research Summary
A recent systematic review and meta-analysis published in the Brazilian Journal of Otorhinolaryngology examined the effectiveness of the video head impulse test (vHIT) in diagnosing vestibular migraine (VM). Analyzing data from nine studies between 2016 and 2023, researchers found that 43% of VM patients had abnormal vHIT results. The test demonstrated a sensitivity of 42% and a high specificity of 89%, with a positive predictive value of 83% and a negative predictive value of 54%. Saccades were detected in 36% of cases. Despite its low sensitivity, vHIT's high specificity suggests it may help confirm VM diagnoses.
