Causes of Blackouts. The most common cause of a blackout is called syncope, (âsin-co-peeâ). Syncope describes blacking out because of a sudden drop in blood flow to the brain. Usually syncope is so-called âReflex Syncopeâ. This is the cause of fainting. The blackout occurs because blood pressure suddenly drops and the brain is temporarily starved of oxygen and glucose. Although a faint can cause accidental injury, it is not dangerous of itself, provided the patient can lie down flat.
