What is Syncope?
Syncope is the temporary loss of consciousness due to a sudden decline in
blood flow to the brain. It may be caused by an irregular cardiac rate or rhythm
or by changes of blood volume or distribution. Syncope can occur in otherwise
healthy people. The patient feels faint, dizzy, or lightheaded (presyncope), or
loses consciousness (syncope).
Is there any treatment?
Non-cardiac syncope is treated acutely by lying down with the legs elevated.
Infrequent episodes of non-cardiac syncope usually do not require treatment.
What is the prognosis?
Syncope is a dramatic event and can even be life-threatening if not treated
appropriately. Generally, however, recovery is usually complete within minutes
to hours.
What research is being done?
The NINDS supports and conducts studies aimed at understanding conditions
such as "neurocardiogenic syncope." The goals of these studies are to clarify
the mechanisms of these conditions and to find ways to prevent and treat them.
