Tests for Vertigo and Dizziness

Vertigo being very common, it is also a particularly confusing because of the words used by patient to describe it. It is confusing because of the number of tests that has to be used to establish its cause and most of all because this one symptom can be due to a wide range of different underlying pathologies. The clinical tests like Electronystagmography and Cranio-corpography are very helpful in diagnosis of vertigo. The study of dizziness or vertigo consists in the application of stimuli on each one of the peripherical sensors proprioceptive, vestibular and visual which are involved in the equilibrium process in order to be able to obtain an answer from the central computer or brain which may be quantitatively and graphically illustrated.

On the other hand, Electronystagmography provides a permanent recording of a nystagmus and it can detect nystagmus which is not readily visible on naked eye examination. It helps to differentiate between peripheral or central origin of vertigo and to support diagnosis and to calculate canal paresis. Cranio corpography is a method for recording and measuring these oscillations rapidly and inexpensively it provides easier diagnosis, follow-up, and measurement of therapeutic effectiveness. 

Cranio-corpography Tests are cheap and easily performed OPD procedure when compare to computerized dynamic posturography which is unimaginable at present state because of high cost. The Electronystagmography test showed paresis in 21% of patients. In 15% of patients, Cranio-corpography test gave positive result. Cranio-corpography is preferred as it is highly efficient in detecting defects in the vestibule-spinal pathway and peripheral vestibular disorder if properly performed.
