The Differential Diagnosis of Ménière's Disease and Vestibular Migraine

The differential diagnosis of Ménière's disease (MD) and vestibular migraine (VM) is difficult, due to a reliance on symptom-based diagnosis despite frequently overlapping symptoms. A systematic review was conducted of studies investigating diagnostic features in patients with MD and VM that may assist differential diagnosis. A scoping review was also conducted of tests with high sensitivity and specificity for MD or VM. The systematic review identified that caloric testing was 54.6% sensitive and 78.9% specific for separating MD from VM (with MD as a positive result). Other potentially useful tests were identified, but more studies are needed. The scoping review identified several tests that not have yet been evaluated for the differential diagnosis of MD and VM (primarily gadolinium magnetric resonance imaging and tone-burst electrocochleography). Several other promising tests were identified, but have not been sufficiently tested with appropriate control groups.
