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.
不睡觉可以缓解depression，那么补偿器不睡觉会影响判断力，不就解释了为什么不睡不被推荐为疗程吗？答案是e，但是很不理解，不是都说不睡了吗

题干的结论是  {尽管其他方法不好，但“不睡觉”也不常用来治疗抑郁}
答案要能推出这个结论  
E说，治疗完，再睡觉，DEPRESSION会returns in full force。 意思是，这个方案不能根治DEPRESSION
这样E当然能推出题干中的结论
