Schellong test positivity was significantly higher in Meniere disease patients compared to BPPV patients (38.8% vs 29.2%), and minimum systolic blood pressure negatively correlated with endolymphatic space ratio.

Does autonomic nervous system dysfunction correlate with endolymphatic space ratio in patients with Meniere disease?
Autonomic nervous system dysfunction is more strongly associated with Meniere disease than BPPV, and greater systolic blood pressure drops during postural changes correlate with increased cochlear endolymphatic hydrops in Meniere disease.
Absolute Event Rate: 38.8% vs 29.2%
p-value: p=0.0427
MRI S-test
Ueda et al. (Fri,) conducted a cross-sectional in Meniere disease (n=168). Schellong test and contrast-enhanced MRI vs. Benign paroxysmal positional vertigo (BPPV) patients was evaluated on Schellong test positivity rate (p=0.0427). Schellong test positivity was significantly higher in Meniere disease patients compared to BPPV patients (38.8% vs 29.2%), and minimum systolic blood pressure negatively correlated with endolymphatic space ratio.
