Which condition is characterized by quadriplegia with preserved consciousness and eye movement?

Explanation:
Recognizing a state of complete paralysis with preserved consciousness and eye movement. Locked-in syndrome occurs from damage to the ventral pons, often due to basilar artery stroke, which shuts down almost all motor pathways leaving cognitive function intact. The person is fully awake and aware but cannot move or speak, though vertical eye movements and blinking are preserved, allowing some communication. This pattern distinguishes it from coma or vegetative states, where wakefulness and eye responsiveness are more limited, and from akinetic mutism, where spontaneous movement and speech are markedly reduced. Language or memory disorders like Wernicke’s or Korsakoff affect cognition in different ways and don’t involve the complete paralysis with preserved consciousness and eye movement characteristic of locked-in syndrome.
