Electrovestibulogram (EVestG): The Separation of Benign Paroxysmal Positional Vertigo and Meniere´s Disease

Electrovestibulography (EvestG), a technique used to measure neuronal activity of the vestibular apparatus and nuclei, has been used. We hypothesise that a novel wavelet based signal processing technique, a Neural Event Extraction Routine can be used to extract new diagnostically meaningful biomarkers from EVestG recordings obtained from Meniere\´s patients. This paper shows the EVestG has the potential to separate Benign Paroxysmal Positional Vertigo and Meniere\´s Disease using a "DC" Biomarker. This "DC" component in the EVestG response appears to correspond to cupula displacement and consequently a threshold shift in the unfiltered EVestG response.
