[Positional nystagmus and other otoneurological manifestations in vascular neurovegetative dystonia].

The position nystagmus and the position syndromum vestibularis as well as other otoneurological manifestations such as vertigo, equilibrium and bearing troubles etc. were investigated in 41 cases. A position nystagmus in 22, spontaneous nystagmus in 3, vertigo in 40, equilibrium disturbances in 26, hearing trouble in 16, audiometric disturbances in 7 and vegetativus reactions in 25 cases were established. It is supposed that the neurosis vegetativa results in a copious otoneurological symptomatics notably of vestibular type often accompanied by vegetativus manifestations. The vertigo is predominantly of the position type and unsystematic in character, occurs almost in all of the cases and is accompanied by position nystagmus in half of the cases. Subjective and objective hearing troubles occur rarely and manifest themselves mainly as a buzzing or slight hearing reduction. The position nystagmus is a common symptomus and therefore position tests should be applied to each case.
