Altered Mental Status is best described as?

• A. Confusion with normal consciousness
• B. Dementia progression
• C. Seizure
• D. Change in level of consciousness

Answer: (D)

Altered mental status is a disturbance in brain function that changes how awake, attentive, and aware a person is. The defining feature is a change in level of consciousness, ranging from mild disorientation to stupor or coma. This sets it apart from other ideas: confusion with normal consciousness isn’t the same as a true alteration in arousal; dementia progression is a chronic, gradual decline rather than an acute or subacute shift in consciousness; and a seizure can cause temporary changes in mental status but is not the general description of AMS itself. So the best description is a change in level of consciousness.
