Pediatric Cerebral Dysfunction Practice Test

Stupor describes a deep, sleep-like state in which arousal is limited and the patient can be awakened only by vigorous or repeated stimulation. After such stimulation, responses are often minimal and not sustained, and the person may not stay awake or engage meaningfully. This sits between coma (where there is no ability to awaken at all) and obtundation (where a patient is drowsy but can be aroused more readily and responds more consistently). A persistent vegetative state involves wakefulness without meaningful interaction or awareness, even if eyes may open and sleep–wake cycles occur. So the description of being deeply asleep and only responding to strong stimulation aligns with stupor.
