| ==Epidemiology and Demographics== | | ==[[Vertigo epidemiology and demographics|Epidemiology and Demographics]]== |
| *Among the patient who presents with [[dizziness]] in the primary care setting, fifty-four percent have vertigo upon investigation.<ref name="Kroenke1992">{{cite journal|last1=Kroenke|first1=Kurt|title=Causes of Persistent Dizziness|journal=Annals of Internal Medicine|volume=117|issue=11|year=1992|pages=898|issn=0003-4819|doi=10.7326/0003-4819-117-11-898}}</ref>

| ==Screening== | | ==[[Vertigo risk factors|Risk Factors]]== |
| *There is insufficient evidence to recommend routine [[screening]] for vertigo.
| |
|
| |
|
| ==Risk Factors== | | ==[[Vertigo screening|Screening]]== |
| *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:
| |
| **In [[vestibular]] [[migraine]] recognized triggers including altered sleep patterns, menstrual cycle, chocolate, red wine, ripened/aged cheese, should be avoided.
| |
| **Avoid drugs or toxins that may cause vertigo.
| |
|
| |
|
| ==Natural History, Complications and Prognosis== | | ==[[Vertigo natural history, complications and prognosis|Natural History, Complications and Prognosis]]== |
| *Complications include:
| |
| **[[Anxiety]]
| |
| **[[Depression]]
| |
| **Difficulty performing daily tasks
| |
| **Diminished quality of life
| |
| **Impaired balance and coordination
| |
| *[[Prognosis]] of vertigo depends upon treating the underlying cause. However, vertigo due to a tumor has a poor prognosis compared to other causes of vertigo.
