Which term describes wakefulness without purposeful responses?

• A. Vegetative state
• B. Coma
• C. Minimally conscious state
• D. Locked-in syndrome

Answer: (A)

Wakefulness without purposeful responses is described by the vegetative state. In this condition, a patient may have periods of eye opening and appear awake, showing sleep–wake cycles, but there is no evidence of awareness of self or surroundings or purposeful, goal-directed behavior. Reflexive movements or sounds can occur, but they are not intentional attempts to interact. This differs from a coma, where there is no wakefulness and no sleep–wake cycles. A minimally conscious state shows reliable, though minimal, signs of awareness and some purposeful responses. Locked-in syndrome is when a person is fully conscious and aware but cannot move or speak due to paralysis, though eye movements can allow communication.
