Syncope (medical symptom): Syncope means loss of consciousness such as fainting. The term "dizziness" is often used for milder feelings of lightheadedness that often precede a fainting episode. The vague word "dizziness" needs to be distinguished from symptoms such as balance difficulty, vertigo, fainting, or general weakness.
