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.

If sleep-deprivation could be used as an effective treatment for severely debilitating depression, the benefit derived would be so great that the occasional extra benefit of euphoria (choice A), the need for expending some extra effort (choice B), the occasional drawback of impaired judgment (choice C), and the lack of thorough scientific understanding (choice D) would each be a comparatively insignificant consideration.

sleep-deprivation是不让谁觉得意思吗？

那么这就不会涉及到E中的睡一会就return的问题啊？

大牛请把整个句子翻译一下，谢谢！

sleep-deprivation就是不让人睡觉的意思啊！答案的意思是说，你越是不让人

睡觉，人越是有可能会睡一会儿，而只睡一会儿就会导致Depression returns in

full force ,所以这种不让人睡觉的治疗方式不能用。

那题目中也没有出现你越不让人睡觉，人就越想睡的意思啊？

请NN解释一下

为什么事E呢？

Re: 那题目中也没有出现你越不让人睡觉，人就越想睡的意思啊？

I think that's common sense, can be assumed when reasoning through this

question.

E explains why this is not used as a treatment because it doesn't cure

or even reduce depression in the long run.
