### HideShow timer Statistics

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.

E. People can't go forever without sleep, so sleep deprevation as a long-term fix for depression is useless.

I'm not a native english speaker, and may be misunderstanding the statement, but, if missing a night's sleep lifts(raises) someone's depression, how can it be good, and used as a treatment against depression?
For me it made no sense.
