Research Summary
A systematic review and meta-analysis published in the Brazilian Journal of Otorhinolaryngology explored the effectiveness of the video head impulse test (vHIT) in diagnosing vestibular migraine (VM). Analyzing data from nine studies, researchers found that 43% of VM patients had abnormal vHIT results. The test showed a sensitivity of 42% and a specificity of 89%, indicating that while it is not highly sensitive, it is quite specific in identifying VM. Additionally, the positive predictive value was 83%, and the negative predictive value was 54%. Saccades were noted in 36% of cases, with varied VOR gains observed.
