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.
要解释“睡眠剥夺可以减轻depression,但不能作为treatment.”，就应指出睡眠剥夺的缺点，那不是就应该选C：长期睡眠缺失可导致判断力损害 吗？

谢谢啦！！

let me try to explain.

the question concerns about depression, nothing else.

conclusion: sleep-deprivation is not used as a treatment for depression.

Premises: 1) majority of people who lost sleep had their depression lifted.
               2) but still not used even though other treatments hv srs side-effect.

Support conclusion?

C说会想酒精一样影响判断能力。但是即便影响了，对于depression的影响到底是什么呢？如果对于depression很有效，伴随着一些对于判断力的影响。 C 是weaken.

E:即便睡几分钟，depression就恢复了。一点没好。说明不睡觉没用。support

hope it helps.

我觉得CHANSINGM7的解释很有道理~
