Brief Summary
BPPV is the most common cause of vertigo. The pathophysiology of BPPV has not been cleared, several studies show that symptoms are caused by the displacement of otoconia from the macula of the utricle into the semicircular canals. These calcium carbonate particles then stimulate non-physiological movement of the endolymph leading to a false sensation of angular acceleration. Biomarkers represent measurable products of biological processes, thus making an assessment of those processes more practical. Biomarkers in circulation are powerful indicators of normal and pathological biological processes, as well as, responses to pharmacological treatments. The inner ear-inclusive protein that has been published included Otolin-1, Otoconin-90/95, Prestin, Otoancorin, Otogelin, α-tectorin, β-tectorin and Cochlin.
