What tests are done to diagnose BPPV?
Diagnosing BPPV involves taking a detailed history of a person’s health. The doctor confirms the diagnosis by observing nystagmus — jerking of the person’s eyes that accompanies the vertigo caused by changing head position. This is accomplished through a diagnostic test called the Dix-Hallpike maneuver.
Can VNG detect BPPV?
Conclusion: Although a subjectively positive Dix-Hallpike or a “supine roll” test is sufficient for the diagnosis of BPPV, it is necessary perform the VNG as well in order to precisely determine the exact localization of the otolith, so that an appropriate repositioning procedure can be applied.
How can you tell the difference between Meniere’s and BPPV?
Sometimes an ear injury can lead to BPPV. Vestibular neuronitis causes severe dizziness that comes on suddenly and lasts for 2 to 3 weeks. Doctors think an infection with a virus may be the cause. Meniere’s disease is condition that combines symptoms of dizziness with occasional hearing loss.

Is VNG test painful?
VNG testing should not cause pain; however, it may cause dizziness and sometimes nausea.
What is the difference between Epley and Dix-Hallpike?
The Dix-Hallpike test is a diagnostic manoeuvre used to identify benign paroxysmal positional vertigo (BPPV). The Epley manoeuvre is used to treat BPPV (usually of the posterior canal) once it has been diagnosed by the previously mentioned Dix-Hallpike test.
Can BPPV be misdiagnosed?
Results: This study showed that the misdiagnosis rate of BPPV was 60.0% (48/80) and the common inappropriate diagnostic tests for BPPV included Cranial CT and MRI test, cervical MRI, cervical and cerebrovascular investigations et al.
