According to a review of 61 studies of patients suffering [#permalink]
 10 Feb 2006, 23:50
Question Stats:
0% (00:00) correct
 0% (00:00) wrong based on 1 sessions
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.
Will post OA later.

I think its E.
All the other answers are not addressing the problem...
While E significantly weakens the argument that sleep-deprivation should be used as treatment....

C, might be tempting, cannot explain in more detail that why sleep is not used to cure the depression. E does so more elboratly.
E is final.

Late, but (E) makes the most logical sense.
