Osmophobia and vestibular migraine
Abstract
AIM: Vestibular migraine is one of the most common vestibular disorders, which includes headache, photophobia, phonopobia and visual auras. Others as osmophobia are common but usually subregistered, and potentially would be involved in the vestibular migraine episodes. The aim of this study was to perform a search about the frequency and clinical interaction between vestibular migraine and osmophobia.
DATA SEARCH: A literature review search was conducted on PubMed, EBSCO, Scielo, Google Scholar and Bvsalud of published studies between 2011 and 2021 using the MeSH terms ‘vertigo and olfaction disorders’, ‘dizziness and olfaction disorders’, ‘migraine disorders and olfaction disorders’.
STUDY SELECTION: 12 articles were found, where patients with diagnosis of vestibular migraine according to Barany Society, reported clinical symptoms and the prevalence of each symptom related was documented. Only two studies, presented relevant information about osmophobia and vestibular migraine
DATA EXTRACTION AND RESULTS: From 277 individuals diagnosed with vestibular migraine in two observational studies, only 5%-12%, reported osmophobia. To date only one case report describe in extension the relationship between vestibular migraine and osmophobia.
CONCLUSIONS: This symptom would be underdiagnosed and subregistered in individuals with vestibular migraine. Further studies are needed to determine this association.
OBJETIVO: La migraña vestibular, es uno de los tipos de alteraciones…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 277 participants or records.
