ICU-Acquired delirium is defined as what?

• A. Fluctuating disturbance of consciousness and cognition due to acute brain dysfunction
• B. Persistent coma
• C. Mood swings
• D. Sleep deprivation

Answer: (A)

ICU-acquired delirium is an acute brain dysfunction that presents with a fluctuating disturbance in consciousness and cognition. You’ll see attention and awareness wax and wane over hours to days, often with disorganized thinking and variable levels of alertness or agitation. This fluctuating pattern is what distinguishes delirium from a persistent coma, mood swings, or simple sleep deprivation, which do not involve this abrupt, variable decline in cognitive function. While sleep loss and other ICU factors can worsen delirium, they don’t define it on their own. Recognizing this pattern is important, and ICU teams often use screening tools like CAM-ICU to detect it and guide management.
