Evanescence's blog / latest words on Dizziness - Posts
(Symptoms may vary in individual cases.)"Dizziness" is a general term, and in usage can mean either vertigo or faintness (incomplete passing out). Vertigo has been defined as an illusion of movement. This illusion can be a sensation of rotation, linear movement or tilt. Faintness, on the other hand, involves at least a partial loss of consciousness.True vertigo is frequently accompanied by symptoms of "imbalance" and/or "nausea" (giddiness), the sensation we get on carnival rides. Vertigo is due to a recent insult to the balance system, usually occurring in the inner ear. Faintness is usually of central vascular origin (inadequate blood supply to the brain), as occurs to the person standing for a prolonged time on a hot day. Thus, most dizziness is vertigo, and most vertigo originates in the inner ear. At least 90% of vertigo is caused by one of the following four common dizziness syndromes (combinations of signs and symptoms) caused by malfunction of the inner ear.
