Assessing the impact of migraine on benign paroxysmal positional vertigo symptoms and recovery.

BACKGROUND: During episodes of benign paroxysmal positional vertigo (BPPV), individuals with migraine, compared with individuals without migraine, may experience more severe vestibular symptoms because of their hyperexcitable brain structures, more adverse effects on quality of life, and worse recovery processes from BPPV. METHODS: All patients with BPPV were assigned to the migraine group (MG, n = 64) and without migraine group (BPPV w/o MG, n = 64) and completed the Vertigo Symptom Scale (VSS), Vertigo Dizziness Imbalance Symptom Scale (VDI-SS), VDI Health-Related Quality of Life Scale (VDI-HRQoLS), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI) at the time of BPPV diagnosis (baseline) and on the one-month follow-up. Headache Impact Test-6 and Migraine Disability Assessment Scale were used for an assessment of headache. Motion sickness was evaluated based on the statement of each patient as present or absent. RESULTS: Compared with the BPPV w/o MG, the MG had higher VSS scores at baseline [19.5 (10.7) vs. 11.3 (8.5); p < 0.001] and on one-month follow-up [10.9 (9.3) vs. 2.2 (2.7), p < 0.001]; experienced more severe dizziness and imbalance symptoms based on the VDI-SS at baseline (61.9% vs. 77.3%; p < 0.001) and after one month (78.9% vs. 93.7%, p < 0.001); and more significantly impaired quality of life according to the VDI-HRQoLS at baseline (77.4% vs. 91.8%, p < 0.001) and after one month (86.3% vs. 97.6%, p < 0.001). On the one-month follow-up, the subgroups of patients with moderate and severe scores of the BAI were higher in the MG (39.2%, n = 24) than in the BPPV w/o MG (21.8%, n = 14) and the number of patients who had normal scores of the BDI was lower in the MG than in the BPPV w/o MG (67.1% vs. 87.5%, p = 0.038). CONCLUSION: Clinicians are advised to inquire about migraine when evaluating patients with BPPV because it may lead to more intricate and severe clinical presentation. Further studies will be elaborated the genuine nature of the causal relationship between migraine and BPPV.

Vestibular disorders in children: A retrospective analysis of vestibular function test findings.

OBJECTIVE: This study was designed to describe the most common vestibular disorders in children and their associated findings on vestibular function testing. METHOD: Data from 203 children with a mean age of 11.16 ± 3.87 (range, 1-17) years were collected from among 3400 patients who underwent vestibular assessment at a vertigo center in a tertiary hospital over a 3-year period. A retrospective data analysis was performed for 203 children. RESULTS: Vestibular disorders were diagnosed in 78.3% (n = 159) of 203 children among 3400 patients, which revealed a 3-year incidence of 4.67% in our study. Benign paroxysmal positional vertigo (BPPV) was the most common diagnosis in our group of children (49%; n = 100), which involved both primary BPPV, and secondary BPPV that was associated with other vestibular pathologies. Vestibular migraine (VM) was the second most common diagnosis (41%; n = 83) followed by benign paroxysmal vertigo of childhood (BPVC; 4.5%, n = 9), vestibular neuritis (VN; 4.5%, n = 9), and psychogenic vertigo (4.5%, n = 9). Our study showed that Meniere's Disease (MD; 1.5%, n = 3) and central vertigo (1.5%, n = 3) were less commonly diagnosed in children. Perilymphatic fistula (PLF) was diagnosed and surgically confirmed in only one child. CONCLUSION: BPPV and VM were the most common pediatric vestibular disorders in our study. Clinicians should be aware of the prevalence, signs, and symptoms of the most common vestibular disorders in children to enable diagnosis, treatment, and rehabilitation. Vestibular function testing with age-appropriate adaptations results in improved differential diagnosis, which guides medical treatment and rehabilitation.

Research on the Effects of a Web-Based System With Oculomotor and Optokinetic Stimuli on Vestibular Rehabilitation.

OBJECTIVE: The variety and use of technologies used in vestibular rehabilitation are very limited. The purpose of this study was to investigate the effects of a Web-based system on vestibular rehabilitation in patients with vestibular hypofunction. DESIGN: A total of 20 patients with unilateral vestibular hypofunction were randomly assigned to two groups. Conventional vestibular rehabilitation was applied to the control group, whereas the study group received treatment with the Web-based system supporting the vestibulo-ocular reflex with oculomotor and optokinetic stimulus (Simulation of Vestibulo-Ocular Reflex Exercises). Vestibular and balance tests, oculomotor level, the Tampa Kinesiophobia Scale, and the Dizziness Handicap Inventory were used to evaluate the treatment's efficacy. RESULTS: Vestibular symptoms and findings, balance tests, oculomotor functions, Tampa Kinesiophobia Scale, and Dizziness Handicap Inventory improved significantly in both groups after the interventions (P < 0.05). In the intergroup analysis, improvement was found in eyes closed Romberg, semitandem, and left one-foot position balance tests in favor of the study group (P < 0.05). CONCLUSION: The new vestibular technology, Simulation of Vestibulo-Ocular Reflex Exercises, was found to be effective in vestibular rehabilitation.
