23. Stupor refers to a condition in which the patient is less alert than usual, but can be stimulated into responding.
24. Obtundation ( 意识模糊 ) describes a patient who appears to be asleep much of the time when not being stimulated. This eyes-closed state is not electroencephalographic sleep, however.

29. Delirium is defined as a disturbance of consciousness that is accompanied by a change in cognition that cannot be better accounted for by a preexisting or evolving dementia.
30. The disturbance develops over a short period of time, usually hours or days, and tends to fluctuate during the course of the day.
31. There is evidence from the history, physical examination, or laboratory tests that the delirium is a direct physiological consequence of a general medical condition, substance intoxication or withdrawal, use of a medication, or toxin exposure, or a combination of these factors.
