Abstract:
Objective:To describe the audiological, vestibular and radiological profile of patients with migrainous
vertigo. Methods: This is a prospective descriptive study of patients who presented with migrainous
vertigo in a tertiary care institute over one year.All patients between the ages of twenty to sixty who
presented between 2013 and 2014 with migrainous vertigo diagnosed according to Neuhauser’s criteria
were included in this study. The diagnostic intervention was audiovestibular tests and magnetic resonance
imaging (MRI) of brain with gadolinium. The main outcome measures were types and degree of
auditory and vestibular deficits; MRI findings in migrainous vertigo, and whether age at presentation
and duration of symptoms affected these findings.Results:Of the 112 patients recruited, the overall
female-to male ratio was 1.7: 1. On pure tone audiogram, 18 (16%) patients had sensorineural hearing
loss and this was similar in age groups<41 and >40 years. Caloric abnormalities were seen in 64
(61.5%) patients and there was no significant difference in the younger versus older age groups. MRI
abnormality was present in 24% and the commonest finding was deep white matter hyperintensities
in the brain. In the <41 age group, there were 8/46 with headache < 7 years (17.3%) and 5/9 (55.5%)
with headache for >7 years with MRI abnormalities, and this difference was statistically significant
(Chi sq 4.14, p=0.041).
Conclusions:Both audiological and vestibular abnormalities were seen in migrainous vertigo patients
and older age did not appear to be an additional risk factor for the presence of theseabnormalities.
Deep white matter hyperintensities were the commonest abnormality found on MRI scans and longer
headache duration was associated with higher chances of MRI abnormalities in younger people.
