Differentiation between normal functioning vestibular system and central vestibular dysfunctions

Vestibular function examination methods are useful for differentiation between normally functioning balance system and vestibular system dysfunctions. A thorough neurotological examination and the instrument of ultrasound-computer-craniocorpography, which applies and assesses the Romberg and Unterberger-Fukuda tests, we categorized the vertiginous population into normal, peripheral and central vestibular system groups.
The objective of this study is to determine the incidence of central vestibular lesion among the vertiginous population and objectively register it.
408 patients were examined with healthy vestibular system and with vertigo attributed to central causes, which were divided according to their complaints and the results of the neurotological examinations. Out of them 221 patients had a normally functioning vestibular system and 187 suffered of a central vestibular dysfunction.
In both statokinetic tests of US-COMP-CCG most of the parameters showed statistical significance, indicating possible central lesions among the patients.
With the appliance of neurotological examinations and the assistance of US-COMP-CCG, we were able to exhibit objectively the existence of central vestibular disorder and increase the detection of it in the vertiginous population participating in our study.
