title: [Vertigo as one of the symptoms of the initial manifestations of a deficient blood supply to the brain in neurocirculatory dystonias].
abstract: In 136 patients aged 17 to 49 years the character of dizziness and the otoneurological symptoms are described. The patients were suffering from neurocirculatory dystonias of the hypo- and hypertensive types. In 124 patients (91.1% of all the cases) objective signs of a vestibular dysfunction were revealed. The greatest part of the patients showed central truncal disturbances the localization of which within the brain trunk could not be specified. In 26 patients the paradoxic phase of the vestibular analyzer excitability was discovered. In 15 patients distinct truncal disturbances (nuclear, supranuclear and combined) were diagnosed, the fact, that gives one grounds to suppose that there are microfocal changes in the central vestibular structures. The data obtained make it possible to regard dizziness as an important symptom for diagnosing initial manifestations of deficient blood supply of the brain.
