Vertigo

Vertigo, a specific type of dizziness, is a major symptom of a balance disorder. It is the

sensation of spinning while the body is stationary with lots to the earth or surroundings.

With the eyes shut, there will be a sensation that the body is in movement, called

subjective vertigo; if the eyes are open, the surroundings will appear to move past

the field of vision, called objective vertigo.

Some people experience a vertigo sensation while looking at such images. The effects

may be slight. It can cause nausea and vomiting or, if severe, may give rise to difficulty

with standing and walking. Vertigo is usually associated with a problem in the inner ear

balance mechanisms (vestibular system), in the brain, or with the nerve connections

between these two organs. The most common cause is benign paroxysmal positional

vertigo, or BPPV. Vertigo can be a symptom of an underlying harmless cause, such as

in BPPV or it can suggest more serious problems. These include drug toxicities, strokes

or tumors (though these are much less common than BPPV). Vertigo can also be brought

on suddenly through various actions or incidents, such as skull fractures, sudden changes

of blood pressure, or as a symptom of motion sickness while sailing, riding amusement

rides or in a vehicle.

Vertigo is typically classified into one of two categories depending on the location of the

damaged vestibular pathway. These are peripheral or central vertigo. Each category has

a distinct set of characteristics and associated findings.

Peripheral vertigo:

The lesions, or the damaged areas, affect the inner ear or the

vestibular division of the acoustic (CN VIII) nerve. Vertigo that is peripheral in origin

tends to be felt as more severe than central vertigo, intermittent in timing, always

associated with nystagmus in the horizontal plane and occasionally hearing loss or

tinnitus (ringing of the ears).

Peripheral vertigo can be caused by BPPV, Ménière's disease or acute vestibular
neuronitis. Peripheral vertigo, compared to the central type, though subjectively

felt as more severe, is usually from a less serious cause.

Central vertigo:

The lesions in central vertigo involve the brainstem vestibular nerve

nuclei. Central vertigo is typically described as constant in timing, less severe in nature

and occasionally with nystagmus that can be multi-directional. Associated symptoms

include motor or sensory deficits, dysarthria (slurred speech) or ataxia.

Causes include things such as migraines, multiple sclerosis or tumors. Less
commonly, strokes, seizures, trauma or infections can cause also central vertigo.

Vertigo should not be confused with dizziness. Dizziness is an unpleasant feeling
