Vestibular Neuritis in Patients Among Different Age Groups: Clinical Features and Outcomes.

Abstract

Patients with vestibular neuritis (VN) displayed differential prognosis despite of the same treatment. Thus, identifying unique characteristics in different populations and creating individually customized treatments are necessary. However, studies about the clinical features according to different ages are scarce. This article compares the differences in VN patients among different age groups. A prospective study. A total of 70 VN patients were enrolled in the present study. All the patients started vestibular rehabilitation at the time of initial presentation to our clinic. They were followed up at 1-month intervals using the questionnaire until 4 months. Patients' clinical data including clinical presentation, vestibular testing results, treatment, and recovery was collected and analyzed with Duncan's multiple range test, the sign test, and the Kruskal-Wallis test using SPSS18.0. The mean age of the 70 patients was 47.2 ± 17.1, ranging from 10 to 76 years old. The sex ratios (male:female) were 3.5 in the adolescent group, 0.643 in the young adult group, 1.375 in the middle-aged group, and 0.583 in the senior group. The prevalence of hypertension and diabetes mellitus showed a significantly increasing trend from young adults to the seniors (p < 0.05). The caloric response was statistically worse in the senior group than the other groups (p < 0.05). The abnormal rates for video head impulse test, vestibular-evoked myogenic potential, and vestibular autorotation test did not differ significantly in different age groups. A significant difference between prerehabilitation and postrehabilitation total Dizziness Handicap Inventory (DHI) scores was identified in all the groups (p < 0.05). The younger patients demonstrated a greater improvement than patients in the senior group, meanwhile adolescents improved the most (p < 0.05). Hospital Anxiety and Depression Scale (HADS) was the lowest in the adolescent group (p < 0.05). DHI score at acute stage was significantly correlated with HADS (r = 0.597, p < 0.05). The canal response was statistically better for younger patients compared with the elderly. The younger patients demonstrated a greater improvement than patients in the senior group, among whom adolescents improved the most, meanwhile psychological factors played a minor role in adolescents. Self-perceived disability-handicap positively correlated with anxiety and depression in all patients.
