Abstract

Multiple sclerosis (SM) is the most frequent inflammatory-demyelinating disease of central nervous system. The character of SM disease provokes that its most frequent symptoms are vertigo, equilibrium disorders and ataxia. Objective method of vertigo estimation is evaluation of the nystagmus via videonystagmography registration (VNG). This examination allows to simultaneously assess the vertical and horizontal component of the nystagmus. It is considered that mainly the vertical nystagmus is characteristic to equilibrium system impairments of the central nervous system, caused also by SM. The study was carried out on 40 patients (28 women, 12 men) with SM diagnosed as a result of neurological examination. 7 patients (17.5%) suffered from sham - movement vertigo, while 33 patients (82.5%) suffered from instability of posture and walking deviation. The videonystagmography examination resulted in the following: deviation of the eye movement was recorded in 26 patients (65%) during either in saccadic test and in smooth pursuit test, optokinetic nystagmus recorded: dissymetric and variable amplitude result in 24 patients (60%), presence of vertical nystagmus component in 30 patients (75%), positional test: directional-changable nystagmus in 8 patients (20%), pendular nystagmus in 4 patients (10%), presence of vertical nystagmus component in 31 patients (77.5%), caloric test: impairments of one of the labyrinth recorded in 12 patients (30%). SM is still the diagnostic and therapeutic problem. During the mentioned tests we have found the quantitative and qualitative changes in VNG recordings. This may be helpful in SM diagnosis, mainly during its early stages.
