Which of the following condition is diagnosed by Hallpike test?

Benign paroxysmal positional veigo (BPPV) is diagnosed by observing a characteristic nystagmus (latent, geotropic, fatigable) when performing the Dix-Hallpike test. BPPV is one of the most common types of peripheral veigo, arising as a result of debris in the posterior semicircular canal. Patients complain of veigo lasting seconds, with no associated hearing loss when in ceain positions.
