Overview
Vertigo (from the Latin vertigin-, vertigo, "dizziness," originally "a whirling or spinning movement," from vertere "to turn"[1]) is a specific type of dizziness, a major symptom of a balance disorder. It is the sensation of spinning or swaying while the body is actually stationary with respect to the surroundings.The effects of vertigo may be slight. It can cause nausea and vomiting and, in severe cases, it may give rise to difficulties with standing and walking.
Classification
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. Vertigo can also occur after long flights or boat journeys where the mind gets used to turbulence, resulting in a person feeling as if they are moving up and down. This usually subsides after a few days.
Causes
Vertigo caused by problems with the inner ear or vestibular system, which is composed of the semicircular canals, the otolith (utricle andsaccule), and the vestibular nerve is called "peripheral", "otologic" or "vestibular" vertigo. The most common cause is benign paroxysmal positional vertigo (BPPV), which accounts for 32% of all peripheral vertigo. Other causes include Ménière's disease (12%),superior canal dehiscence syndrome, labyrinthitis and visual vertigo. Any cause of inflammation such as common cold, influenza, and bacterial infections may cause transient vertigo if it involves the inner ear, as may chemical insults (e.g., aminoglycosides) or physical trauma (e.g., skull fractures). Motion sickness is sometimes classified as a cause of peripheral vertigo.
Differentiating Vertigo from other Diseases
Epidemiology and Demographics
- Among the patient who presents with dizziness in the primary care setting, fifty-four percent have vertigo upon investigation.
Risk Factors
- There are no established risk factors for vertigo, as it is a symptom of an underlying disease.
- However, vertigo can be prevented in some cases by controlling the underlying cause.
Diagnosis
CT
CT less optimal for imaging cerebellum
