Fainting, which medical professionals call syncope (pronounced SIN-ko-pea), is a temporary loss of consciousness. Unlike a seizure, the person who faints usually regains alertness soon after regaining consciousness. Fainting is caused by a temporary loss of the brain’s blood supply. Fainting can sometimes be a sign of a more serious condition.
People of any age can faint, but elderly persons more often have a serious underlying cause.
