MeSH	D013575

Pre-syncope is lightheadedness,^[1] muscular weakness and feeling faint as opposed to a syncope, which is actually fainting. Pre-syncope does not result from primary central nervous system pathology, nor does it originate in the inner ear but 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.
