118. 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.

The more severely sleep-deprived a patient would be, the more likely it would be that the patient would, whenever possible, catch at least a few minutes of sleep, and according to choice E, depression would then return in full force. This could explain why sleep-deprivation is not used to treat depression, so choice E is the best answer.

我当时看到题目的时候，反应是“难道他们从此都不睡觉了？？？”，我觉得，既然睡一小会都会引起疾病的反弹，那如果治疗会引发失眠不时正好马？所以没选。　虽然有点荒谬，但是我始终想不通。

恳请妞妞指点
