What term describes a state where a person can be aroused only with a painful stimulus?

The term that describes a state where a person can be aroused only with a painful stimulus is "stuporous." In this condition, the individual is in a state of altered consciousness and typically has a significantly reduced level of awareness and responsiveness. While the person may not respond to verbal commands or other less intense stimuli, they can be awakened through more intense stimuli, such as pain.

This state is different from being comatose, where there is a complete lack of responsiveness to any stimuli, including painful ones. Consciousness implies the ability to respond to stimuli meaningfully and demonstrates awareness, while being alert refers to a fully awake and aware state. Thus, stupor is specifically characterized by this partial responsiveness, making it the appropriate term for this phenomenon.
