[Vestibulo-ocular reflexes in patients with chronic impairment of cerebral circulation].
Vestibular dysfunction was studied in 95 patients with initial cerebral circulatory insufficiency (CCI) stage I and II. Sinusoidal rotation proved highly effective in staging the disease, as initial CCI responses with vestibular hyperreflexia to sinusoidal rotation with closed eyes. With CCI progression, some patients demonstrated inhibition of vestibular excitability while other patients had enhanced excitability. This shows clinical heterogeneity of CCI stage II. P-waves correlating with marked vestibulocerebellar symptoms and high vestibular excitability evidence for CCI stage II. It is established that severity of impairment of nystagmus suppression with glance fixation on a moving object depends on the disease stage.
