Abnormalities of the vestibular system often result in vertigo, an illusory sense of motion of self or surround, which is associated with significant disability, including loss of work time and interruption of daily activities [].Vestibular vertigo may arise from peripheral lesions (eg, labyrinth or vestibular nerve) or central lesions (eg, brainstem or cerebellum). Physical examination involves a neurological, cardiovascular, eye and ear examination. Symptoms may include faintness, loss of balance, vertigo, difficult-to-describe light-headed or swimming sensations, or a combination. Nystagmus is a rhythmic movement of the eyes that can have various causes. Vertigo, which is an illusion of movement, is a definite symptom. Vestibular disorders can result in nystagmus because the vestibular system and the oculomotor nuclei are interconnected.
