What is a key characteristic of delirium?

Explanation:
Delirium presents as an abrupt change in mental status with inattention and a fluctuating level of consciousness. The defining feature is the sudden onset, often developing over hours to days, with symptoms that vary in intensity throughout the day. This fluctuating course helps distinguish delirium from other cognitive issues like dementia, which is chronic and progressive. Delirium is not asymptomatic; patients exhibit confusion, disorganized thinking, and changes in awareness, and it is not something present at birth but typically arises in the context of an acute medical condition, infection, surgery, or substance effects. So the best description is an acute onset with a fluctuating course.
