[Physiological nature and diagnostic implications of rotational nystagmus]

Abstract

The authors provide a rationale for clinical studies of four types of rotational nystagmus, true vestibular, cervico-vestibular, opto-vestibular, and cervico-optovestibular. A physiological concept of nystagmus during active head rotation is formulated. Negative consequences of vestibular nystagmus as a pathophysiological reaction are discussed. The main criteria for nystagmometric differential diagnosis of peripheral vestibular and central disorders are proposed. Diagnostic potential of the new <<Neuro-KM - Electronystagmograph>> system is demonstrated.
