Choice C reason: Disturbances in the sleep-wake cycle are more characteristic of delirium and some types of dementia but are not the defining difference between delirium and Alzheimer’s dementia.
Choice D reason: Dementia is usually chronic and progressive, and full recovery is rare; this statement is inaccurate.
