Unconsciousness may occur as the result of traumatic brain injury, brain hypoxia (inadequate oxygen, possibly due to a brain infarction or cardiac arrest), severe intoxication with drugs that depress the activity of the central nervous system (e.g., alcohol and other hypnotic or sedative drugs), severe fatigue, pain, anaesthesia, and other causes.

Prolonged unconsciousness is understood to be a sign of a medical emergency. [3] A deficit in the level of consciousness suggests that both of the cerebral hemispheres or the reticular activating system have been injured. [4] A decreased level of consciousness correlates to increased morbidity (sickness) and mortality (death). [5]
