Definition
Vertigo
The word "vertigo" comes from the Latin "vertere", to turn + the suffix "-igo", a condition = a condition of turning about.
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.
Disequilibrium
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.
Pre-Syncope
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 syncope.
Lightheadedness
Lightheadedness is a common and often unpleasant sensation of dizziness and/or feeling that one may be about to faint, which may be transient, recurrent, or occasionally chronic. In some cases, the individual may feel as though his or her head is weightless. It can be simply an indication of a temporary shortage of blood or oxygen to the brain, low blood pressure, low blood sugar, or anemia. It can also be a symptom of many other conditions, some of them serious, such as heart disease, stroke, or bleeding.
