Bárány Society consensus criteria. Definition: chronic vestibular syndrome with unsteadiness worsening in darkness/uneven ground and head-motion-induced oscillopsia, with bilaterally impaired or absent VOR. Quantitative thresholds: horizontal aVOR gain <0.6 on both sides (vHIT 150–300°/s) OR caloric sum <6°/s per side OR rotational chair gain <0.1 at 0.1 Hz. DVA ≥0.2 logMAR decrease is a recognised complementary test.

Joint Bárány Society and International Headache Society consensus. Two categories: vestibular migraine and probable vestibular migraine. Diagnosis requires ≥5 episodes of moderate or severe vestibular symptoms lasting 5 min to 72 h, migraine history (current or past), migraine features in ≥50% of vestibular episodes, and exclusion of other causes. Probable VM requires only one of the migraine criteria. Vestibular migraine is included in the appendix of ICHD-3.

Comprehensive review of aminoglycoside-induced vestibular deficits. Mechanism: gentamicin is concentrated in vestibular hair cells via mechanotransduction channels; type I hair cells more vulnerable than type II. Vestibulotoxicity often outpaces cochleotoxicity and may be unrecognised when monitoring is audiology-only. Argues for routine vestibular monitoring independent of auditory monitoring.
