| auditory vertigo | <neurology> A name applied to recurrent vertigo accompanied by ringing in the ears (tinnitus) and deafness. A dysfunction of the semi-circular canals (endolymphatic sac) in the inner ear. Symptoms include dizziness, hearing loss (one-sided), vertigo, nausea, vomiting and abnormal eye movements. Treatment includes anticholinergics, antihistamines and other medications which relieve vertigo. Diuretic medications have been used to lower pressure in the endolymphatic sac. (27 Sep 1997) |

| benign positional vertigo | Brief attacks of paroxysmal vertigo and nystagmus that occur solely with certain head movements or positions, e.g., with neck extension; due to labyrinthine dysfunction. Synonym: positional vertigo of Barany, postural vertigo. (05 Mar 2000) |
