In the whole cohort, 21 (26%) had significant semicircular canal abnormalities (low vestibular-ocular reflex (VOR) gain, high VOR gain or saccades in the video head impulse test). Neurovestibular signs to assess vestibular angular and gravitational motion sensor function were abnormal in 37 children (45%). Abnormal central oculomotor signs were detected in 20 (25%). 20 (25%) had one abnormal finding whilst 31 children (38%) had ≥2 clinical and/or diagnostic abnormalities. 30 (37%) had normal examination and diagnostic findings. Results: 81 children (M:F 38:43 2–17 years) were identified. The results were analysed and statistically evaluated. Children underwent intense neurovestibular examination/investigations including videonystagmography and vestibular function tests. The diagnostic criteria of VM/BPVC was based on the Barany Society criteria (2012). Methods: A retrospective case note review was undertaken on all patients with VM at a tertiary Paediatric Audiovestibular Medicine clinic between January and December 2018. The aim of this study is to investigate this important aspect to aid in the diagnostic process.
There is meagre evidence regarding neurovestibular examination/quantification in paediatric VM. Diagnosis is important as it leads to successful management. Objective: Vestibular Migraine (VM) including its variant Benign Paroxysmal Vertigo of Childhood (BPVC) is the commonest cause of childhood dizziness.
