Which finding would most strongly suggest delirium rather than dementia in a long-term care client?

• A. Gradual memory loss
• B. Reduced level of consciousness
• C. Difficulty with abstract thought
• D. Verbalized feelings of hopelessness

Answer: (B)

Delirium shows up as an acute, sudden change in mental status with fluctuations in attention and an altered level of consciousness. In a long-term care resident, a reduced level of consciousness—being unusually sleepy, sluggish, or hard to arouse—points most strongly to delirium, especially if the change came on quickly or varies from moment to moment. Dementia, by contrast, is a gradual, chronic decline in memory and thinking that develops over months to years, with consciousness typically preserved early on. So the most telling sign that distinguishes delirium from dementia is an altered, reduced level of consciousness. Gradual memory loss aligns with dementia, not the acute, fluctuating state of delirium. Difficulty with abstract thought can occur as dementia progresses and isn’t as specific to delirium. Verbalized feelings of hopelessness reflect mood concerns and are not the hallmark of an acute cognitive disturbance like delirium.
