Vertigo

Vertigo /ˈvɜː(ɹ)tɨɡoʊ/ (from the Latin vertō "a whirling or spinning movement") is a subtype of dizziness, where there is a feeling of motion when one is stationary. The symptoms are due to an asymmetric dysfunction of the vestibular system in the inner ear. It is often associated with nausea and vomiting as well as a balance disorder, causing difficulties standing or walking. There are three types of vertigo: (1) Objective− the patient has the sensation that objects in the environment are moving; (2) Subjective− patient feels as if he or she is moving; (3)Pseudovertigo− intensive sensation of rotation inside the patient's head. While appearing in textbooks, this classification has little to do with pathophysiology or treatment.
