A stroke is the cause of isolated dizziness in 0.7% of people who present to the emergency department.[5] ClassificationDizziness is broken down into 4 main subtypes: vertigo (~50%), disequilibrium (less than ~15%), presyncope (less than ~15%) and lightheadedness (~10%).[5] MechanismMany conditions cause dizziness because multiple parts of the body are required for maintaining balance including the inner ear, eyes, muscles, skeleton, and the nervous system.[6] Common physiological causes of dizziness include:
DiagnosisDifferential diagnosisMany conditions are associated with dizziness. Dizziness can accompany certain serious events, such as a concussion or brain bleed, epilepsy and seizures (convulsions), strokes, and cases of meningitis and encephalitis. However, the most common subcategories can be broken down as follows: 40% peripheral vestibular dysfunction, 10% central nervous system lesion, 15% psychiatric disorder, 25% presyncope/disequilibrium, and 10% nonspecific dizziness.[9] Some vestibular pathologies have symptoms that are comorbid with mental disorders.[10] The medical conditions that often have dizziness as a symptom include:[9][11][6][12]
EpidemiologyAbout 20–30% of the population report to have experienced dizziness at some point in the previous year.[14] See also{{div col|colwidth=22em}}
