Vertigo

Vertigo, sensation of spinning around or of seeing nearby objects revolve. Vertigo tends to be accompanied by nausea, vomiting, headache, or sweating.

Diseases of the cerebral cortex, eye muscles, or cerebellum can cause true vertigo, but such diseases are rare. Inflammation, infection, or other diseases of the semicircular canals of the inner ear, such as labyrinthitis (inflammation of the labyrinth), are more common causes and are frequently accompanied by auditory sensations, such as deafness and ringing in the ear (aural vertigo), and by rapid eye movements (nystagmus). These diseases generally last only a few weeks, during which the vertigo is usually experienced briefly and intermittently.
