In a vegetative state, which feature is typically observed?

• A. Wakefulness with awareness
• B. Wakefulness without awareness
• C. No wakefulness
• D. Full cognitive function

Answer: (B)

After a severe brain injury, levels of consciousness differ. In a vegetative state, the person shows wakefulness without awareness. They may have sleep-wake cycles and eyes open, appearing aroused, but there is no evidence of purposeful, conscious processing or reliable interaction with the environment. They don’t follow commands or engage in goal-directed behavior, and any movements are usually reflexive rather than intentional. This is distinct from no wakefulness (coma) and from states with some awareness or full cognitive function.
