Many different terms are often used to describe what is collectively known as [[dizziness]]. Common descriptions include words such as [[lightheaded]], floating, whoozy, giddy, confused, helpless or fuzzy. [[Vertigo]], '''Disequilibrium''' and '''[[Pre-syncope]]''' are the terms in use by most doctors. [[Dizziness]] is sometimes a symptom of a [[balance disorder]].

{{main|vertigo (medical)}}
==[[Dizziness historical perspective|Historical Perspective]]==
''The word "[[vertigo]]" comes from the Latin "vertere", to turn + the suffix "-igo", a condition = a condition of turning about.'' 


[[Vertigo (medical)|Vertigo]] is a specific medical term used to describe the sensation of spinning or having the room spin about you. Most people find [[vertigo]] very disturbing and often report associated [[nausea]] and [[vomiting]]. 
==[[Dizziness classification|Classification]]==


===Otologic causes of vertigo===
==[[Dizziness pathophysiology|Pathophysiology]]==


Typically if the [[vertigo]] arises from the inner ear, it is severe and has associated [[nausea]] and [[vomiting]]. One common cause of otologic vertigo is [[benign paroxysmal positional vertigo]] [[BPPV]]. Alternate causes of [[vertigo]] originating from the inner ear include [[Meniere's disease]] and [[labyrinthitis]].
==[[Dizziness causes|Causes]]==


[[Central nervous system]] causes of [[vertigo]]:
==[[Dizziness differential diagnosis|Differentiating Dizziness from other Diseases]]==


If [[vertigo]] arises from the balance centers of the brain, it is typically more mild, and usually has accompanying neurologic deficits, such as slurred speech, [[double vision]] or [[nystagmus]]. Alternately, brain pathology can cause a sensation of disequilibrium which is an off-balance sensation.
==[[Dizziness epidemiology and demographics|Epidemiology and Demographics]]==


==Disequilibrium==
==[[Dizziness risk factors|Risk Factors]]==


[[Equilibrioception|Disequilibrium]] is the sensation of being off balance, and is most often characterized by frequent falls in a specific direction. This condition is '''not''' often associated with [[nausea]] or [[vomiting]].
==[[Dizziness screening|Screening]]==


==Pre-syncope==
==[[Dizziness natural history, complications and prognosis|Natural History, Complications and Prognosis]]==


[[fainting|Pre-syncope]] is most often described as lightheaded or feeling faint. [[Syncope]], by contrast, is actually fainting. [[Pre-syncope]], or [[lightheadedness]], does not result from primary [[central nervous system]] pathology. Nor does it originate in the inner ear. It is most often cardiovascular in etiology. In many patients, [[lightheadedness]] is a symptom of [[orthostatic hypotension]]. [[Orthostatic hypotension]] occurs when the blood pressure drops significantly when the patient stands from a supine or seated position. If loss of [[consciousness]] occurs in this situation, it is termed [[fainting|syncope]].
