Vertigo is an unpleasant distortion of static gravitational orientation or an erroneous perception of motion of either the sufferer or the environment. It is not a well-defined disease entity, but rather the outcome of many pathological processes causing a mismatch between the visual, vestibular, and somatosensory systems, all of which subserve both static and dynamic spatial orientation. Physiological and clinical vestibular vertigo syndromes are commonly characterized by a combination of phenomena involving perceptual, ocular motor, postural and vegetative manifestations: vertigo, nystagmus, ataxia and nausea. The vertigo itself results from a disturbance of cortical spatial orientation, while nystagmus and ocular deviations are secondary to a direction-specific imbalance in the vestibulo-ocular reflex. Postural imbalance and vestibular ataxia are caused by inappropriate or abnormal inactivation of vestibulospinal pathways. Unpleasant vegetative effects, such as nausea and vomiting, are related to clinical activation of the medullary vomiting centre |
