When studying the vestibular apparatus of healthy adolescents by the method of electron-stagmography after a rotational test, 23 of 36 adolescents revealed secondary nystagmus. Secondary nystagmus was often observed and was more pronounced to the left. Its duration exceeded the duration of primary nystagmus, but the intensity in terms of frequency, amplitude and speed of the slow phase was much less. Secondary nystagmus was closely associated with latent spontaneous nystagmus. The latter has always been accompanied by prolonged secondary nystagmus in the same direction. Detection of prolonged unilateral secondary nystagmus should obviously have the same significance for issues of professional suitability as the detection of latent spontaneous nystagmus.
To establish the degree of functional imbalance in patients with cervical osteochondrosis outside the stage of exacerbation of the disease. Material and methods: Rotational test was performed in 36 patients with spontaneous nystagmus and 6 patients with cervical positional nystagmus (. The subject was rotated according to a trapezoidal program with an angular acceleration of ±60°/s2 (2 s) and uniform rotation between acceleration and deceleration for 60 s. The patient is rotated (the head is tilted forward and downward by 30°) in the Barani chair - 10 revolutions per 20 seconds clockwise (to the right). Results: In 66 patients, asymmetry of radiological changes in the cervical spine was noted, in 61 cervical positional nystagmus. Conclusions: The applied technique can serve as a reliable differential diagnostic test in determining vestibulopathy of vertebrobasilar genesis.
Current investigation includes data of 49 patients with chronic subdural hematomas (CSH). Performed analysis of dependence of clinical-neurological investigations from volume and localization of CSH. It was carried out complex clinical and instrumental investigation, including computed and magnetic-resonance to-mography. Study of course and diagnostic features of CSH allows setting timely diagnosis and decrease of sev-eral negative complications
The course of Meniere’s disease is observed in every second patient and even more often. Despite the high frequency of monosymptomatic development of the disease, many authors regarded this as an atypical course of Meniere’s disease and even distinguished its cochlear and vestibular forms. In our opinion, no convincing arguments in favor of this point of view are given. 52 people were examined who underwent otorhinolaryngological examination, detailed audiometric and vestibulometric examination. In each of the examined groups of patients, a decrease in excitability on the side of the lesion was the most typical reaction of the vestibular system to the hydrops of the labyrinth.
Vestibular disorders caused by circulatory insufficiency in the vertebral-basilar system (PBS) indicate isolated or concomitant conditions of acute ischemia of the structures of the inner ear and the VIII nerve root, as well as symptoms of their chronic ischemic lesion. Peripheral dizziness and nystagmus observed in vascular disorders occurring against the background of atherosclerosis and hypertension may be the earliest symptoms of the disease, and therefore their adequate diagnosis is extremely important.
In this article we studied cause of origin, clinical-neurological manifestation, modern methods of diag-nostics and their results in 39 patients with acquired hydrocephalus. We described brain and focal symptoms and their clinical significance, essence of modern methods of diagnostics on acquired hydrocephalus
