Vertigo, or dizziness, usually results from a disorder in the peripheral vestibular system (i.e., structures of the inner ear). Dizziness also may occur as a result of a disorder in the central vestibular system (i.e., vestibular nerve, brainstem, and cerebellum). In some cases, the cause of vertigo is unknown.
Peripheral vestibular disorders include the following:
Benign paroxysmal positional vertigo (BPPV; most common peripheral disorder; may be accompanied by hearing loss, reduced cognitive function, and facial muscle weakness)
Cogan's syndrome (inflammation of connective tissue in the cornea; results in vertigo, ringing in the ears [tinnitus], and loss of hearing)
Meniere's disease (fluctuating pressure of inner ear fluid [endolymph]; results in severe vertigo, ringing in the ears [tinnitus], and progressive hearing loss)
Ototoxicity (i.e., ear poisoning)
Vestibular neuritis (inflammation of vestibular nerve cells; may be caused by viral infection)
