Vertigo is a symptom of a wide range of medical conditions and problems involving the inner ear or brain, so there isn’t one single test, but rather a series of examinations and maneuvers to determine the triggering factors and whether it’s peripheral or central. Eyes, ears, and balance tests are usually performed first to identify other symptoms other than dizziness. To establish if it’s peripheral or central, a specialist can also perform head movements (e.g., Epley maneuver, Semont maneuver, Foster maneuver, Dix-Hallpike maneuver, and HINTS exam), some of which can also treat the symptoms. When the symptoms’ origins are unclear, an electroencephalogram (EEG), a head computed tomography (CT) scan, a magnetic resonance imaging (MRI) scan, electronystagmography (ENG), or a blood test may be requested.
