vertigo

 [ver´tĭ-go]
a sensation of rotation or movement of one's self (subjective vertigo) or of one's surroundings (objective vertigo) in any plane. The term is sometimes used erroneously as a synonym for dizziness. Vertigo may result from diseases of the inner ear or may be due to disturbances of the vestibular centers or pathways in the central nervous system.
benign paroxysmal positional vertigo recurrent vertigo and nystagmus occurring when the head is placed in certain positions, usually not associated with lesions of the central nervous system.
benign positional vertigo (benign postural vertigo) benign paroxysmal positional vertigo.
central vertigo that due to disorder of the central nervous system.
cerebral vertigo vertigo resulting from a brain lesion, such as in meningogenic labyrinthitis. Called also organic vertigo.
disabling positional vertigo constant vertigo or dysequilibrium and nausea in the upright position, without hearing disturbance or loss of vestibular function.
labyrinthine vertigo Meniere's disease.
organic vertigo cerebral vertigo.
peripheral vertigo vestibular vertigo.
positional vertigo that associated with a specific position of the head in space or with changes in position of the head in space.
vestibular vertigo vertigo due to disturbances of the vestibular centers or pathways in the central nervous system.

cerebral vertigo

Etymology: L, cerebrum, brain, vertigo, dizziness
vertigo that is caused by organic brain disease. See also central vertigo.

cerebral vertigo

A nonspecific term for vertigo caused by an organic brain disease; e.g., central vertigo.

vertigo

(ver'ti-go) (ver-ti'go) [L. vertigo, a turning round]
The sensation of moving around in space (subjective vertigo) or of having objects move about the person (objective vertigo). Vertigo is sometimes inaccurately used as a synonym for dizziness, lightheadedness, or giddiness. It may be caused by a variety of entities, including middle ear disease; toxic conditions such as those caused by salicylates, alcohol, or streptomycin; sunstroke; postural hypotension; or toxemia due to food poisoning or infectious diseases. See: vection (2)

Patient care

Assessment should include whether the patient experiences a sense of turning or whirling and its direction; whether it is intermittent and the time of day it occurs; whether it is associated with drugs, turning over in bed, occupation, or menses; whether it is associated with nausea and vomiting or with nystagmus and migraine. Safety measures, such as the use of siderails in bed, are instituted. The patient should ambulate gradually after a slow, assisted move from a sitting position. The call bell should be available at all times; tissues, water, and other supplies should be within easy reach; and furniture and other obstacles should be removed from the path of ambulation. The patient who has undergone ear surgery and experiences severe vertigo should be confined to bed for several days and then begin to gradually increase activity.

alternobaric vertigo

Vertigo associated with a sudden decrease in the pressure to which the inner ear is exposed. This could occur when a scuba diver ascends quickly or when an aircraft ascends quickly.

auditory vertigo

Vertigo due to disease of the ear.

benign paroxysmal positional vertigo

Abbreviation: BPPV
A disorder of the inner ear (labyrinth) characterized by intermittent attacks of vertigo triggered by positional changes of the head. Each episode of vertigo may last from less than a minute to a few minutes, with varying degrees of symptom severity. Episodes may recur for weeks intermittently over a period of years.

Symptoms

A sudden change in head position (such as turning over from one side to another in bed) brings on symptoms that may include dizziness or vertigo, lightheadedness, imbalance, and nausea. Dropping the head back when lying down, rolling over in bed, and getting out of bed are common problematic motions. BPPV may be called “top shelf” vertigo because its sufferers often feel dizzy and unsteady when tipping their heads back to look up. Stationary beauty parlor hairdryers may bring on symptoms. Symptoms of vertigo are often accompanied by nystagmus.

Patient care

Motion sickness medications (e.g., the antihistamine meclizine) may be prescribed to control associated nausea. Several physical maneuvers (habituation or Brand-Daroff exercises) taught to the patient provide effective relief of symptoms.
