Dizziness refers to an impairment in spatial perception and stability.[1] It is considered imprecise.[2] It can be used to mean vertigo, presyncope, disequilibrium,[3] or for a non-specific feeling such as giddiness or foolishness.[4]
- Vertigo is a specific medical term used to describe the sensation of spinning or having one's surroundings spin about them. Many people find vertigo very disturbing and often report associated nausea and vomiting.
- 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.
- Non-specific dizziness is often psychiatric in origin. It is a diagnosis of exclusion and can sometimes be brought about by hyperventilation.[5]
