ABSTRACTPatients after vestibular neuritis (VN) often report persistent dizziness and disequilibrium. We correlated persistent symptoms with sustained impairment of the high-acceleration horizontal vestibulo-ocular reflex as determined by quantitative search-coil head-impulse testing (qHIT). In 47 patients, qHIT was recorded 0-60 months and symptoms assessed with the Yardley Vertigo Symptom Scale short form ≥18 months after VN onset. No correlation between the magnitude of highacceleration vestibular impairment and the severity of vertigo symptoms was observed. The lack of symptom-qHIT correlation suggests that defective compensation at more rostral level in the central nervous system may be responsible for protracted symptoms in VN patients.3 -Palla et al.
