Research Summary
A systematic review and meta-analysis in the Brazilian Journal of Otorhinolaryngology evaluated the accuracy of the video head impulse test (vHIT) in diagnosing vestibular migraine (VM). Analyzing nine studies from 2016 to 2023, the research found that 43% of VM patients showed abnormal vHIT results. The test exhibited a sensitivity of 42% and a specificity of 89%, with a positive predictive value of 83% and a negative predictive value of 54%. Saccades were seen in 36% of cases, while normal and low vestibulo-ocular reflex (VOR) gains were observed in 22% and 12% of cases, respectively. The study noted high heterogeneity in outcomes.
