Factors implicated in response to treatment/prognosis of vestibular migraine
Abstract
PURPOSE: To identify patient factors that influence response to therapy in patients with vestibular migraines.
METHODS: A retrospective cohort study was performed at a university-based tertiary medical center.
PATIENTS: 47 patients evaluated for treatment of definite vestibular migraine, per the Barany Society criteria, from 2015 to 2019.
INTERVENTIONS: A protocol of antidepressants, antiepileptics, beta blockers, and vestibular rehabilitation. Patients failing initial therapy received botulinum toxin per the PREEMPT protocol. Vestibular rehabilitation for motion desensitization in case of known vestibular dysfunction.
OUTCOME MEASURES: Quality of life measured per the dizziness handicap inventory (DHI). Pre- and post-treatment DHI scores (total and domain scores) and change in DHI were correlated against patient-specific variables to determine factors associated with change in response to therapy. Patient factors included demographic variables, medical comorbidities, comorbid otologic or pain symptoms, treatment modality, and initial DHI scores.
RESULTS: 47 patients underwent therapy for vestibular migraine. This population had a significant DHI reduction of 17.3 ± 25.2 (p < 0.001) with therapy. Univariate analysis showed that female gender, comorbid benign paroxysmal positional vertigo, and high initial DHI were significantly associated with greater reduction in DHI scores (ß = - 7.92, p = 0.033; ß = - 18.65, p = 0.028; ß = - 0.458, p = 0.016, respectively). Conversely,…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 47 participants or records.
