Which term may be used to describe a person experiencing confusion, slowed thinking, loss of balance, and impaired vision?

The term "altered mental status" is appropriate for describing a person showing confusion, slowed thinking, loss of balance, and impaired vision. This term denotes a change from the individual's normal cognitive functioning. It encompasses various states where a person's awareness, attention, and ability to process information are compromised.

In contrast, "comatose" refers to a state of deep unconsciousness where the individual cannot be awakened and fails to respond to stimuli, which does not align with the signs of confusion or slowed thinking. "Unconscious" also indicates a lack of awareness or responsiveness, lacking the cognitive confusion and impaired balance described. Similarly, "unresponsive" implies that the individual does not respond to any stimuli, which again does not capture the full range of symptoms, including confusion and slowed thinking. Thus, "altered mental status" is the most fitting and comprehensive term to describe the scenario presented.
