According to a review of 61 studies of patients suffering from severely debilitating depression, a large majority of the patients reported that missing a night's sleep immediately lifted their depression. Yet sleep-deprivation is not used to treat depression even though the conventional treatments, which use drugs and electric shocks, often have serious side effects.
Which of the following, if true, best explains the fact that sleep-deprivation is not used as a treatment for depression?
(A) For a small percentage of depressed patients, missing a night's sleep induces a temporary sense of euphoria.
(B) Keeping depressed patients awake is more difficult than keeping awake people who are not depressed.
(C) Prolonged loss of sleep can lead to temporary impairment of judgment comparable to that induced by consuming several ounces of alcohol.
(D) The dramatic shifts in mood connected with sleep and wakefulness have not been traced to particular changes in brain chemistry.
(E) Depression returns in full force as soon as the patient sleeps for even a few minutes.
题目分析：A说对于一小部分病人来说，睡眠可以诱发临时的兴奋感，很扯，杀。B说让那些抑郁的病人醒着比让那些不抑郁的人醒着要更困难，没提过，杀。C说丢失睡眠能导致判断力损伤，这种损伤类似于喝了很多酒对于判断力造成的损伤，拿丢失睡眠造成的损伤和酗酒造成的损伤做了类比，没说过，杀。D说心情的变化和大脑中的化学物质有关系，有幻觉的答案，杀。E说抑郁在病人睡了一会之后会马上恢复，强调的就是抑郁的睡眠之间的关系，原文反复谈的就是这种关系，留着。
