Electronystagmography in the pathology of the central nervous system

The program of the electronystagmographic examinations in the pathology of the central nervous system contains 11 groups of tasks. Sixty signs of central impairments are listed, from which 26 nystagmic irregularities had a small diagnostic value. No sign occuring alone could be taken as pathognomonic, only a group of signs can be used for the impairment localization. Besides for the peripheral vestibular and the peripheral vestibulocochlear impairments, the authors succeeded to make a group containing pathogomonic signs for mixed vestibular impairments as well as for multiple sclerosis affecting vestibular structures.
