Any alteration of consciousness is considered a medical emergency and immediate medical evaluation and treatment should be provided.
Stupor can be caused by trauma, narcotics, adverse changes within the brain such as a stroke, carbon monoxide poisoning – prompt medical attention is crucial to prevent brain damage and death.
