题太长,就是说对于有depression的 patients,不要采取sleep-deprivation疗法.问哪个解释了这一观点.

正确选项表明sleep-deprivation应该是催眠等帮助睡眠的东西.是这个意思吗?我在字典上没查到~~

The Causes, Effects and Dangers of Sleep Deprivation

Sleep deprivation is a common condition that afflicts 47 million American adults, or almost a quarter of the adult population. Symptoms can interfere with memory, energy levels, mental abilities, and emotional mood. A study conducted by the University of Chicago Medical Center in 1999 indicates that the condition drastically affects the body's ability to metabolize glucose, leading to symptoms that mimic early-stage diabetes.

Symptoms

Exhaustion, fatigue and lack of physical energy are common sleep deprivation symptoms. Exhaustion and fatigue affect our emotional moods, causing pessimism, sadness, stress and anger. The National Sleep Foundation (NSF) has suggested that social problems such as road rage may be caused, in part, by a national epidemic of sleepiness.

The brain's frontal cortex relies on sleep to function effectively. Insufficient rest adversely affects the frontal cortex's ability to control speech, access memory, and solve problems. The effect on physical energy is also startling: otherwise healthy people quickly show symptoms of age and early diabetes as glucose metabolism falls by up to forty percent. These physical reactions disappear when the test subject is allowed to rest properly. Driving and other activities can become dangerous without sufficient rest.

Causes

Emotional stress or excitement can interfere with sleeping patterns, as can some medical conditions and medication. Food additives and caffeine can also make falling asleep difficult.

Over seventy identified sleeping disorders can disrupt normal nighttime patterns, and more disorders may yet be discovered.
我看,sleep deprivation 的意思就是失眠,缺觉

根据题目来看好象应该是相反的意思.题目如下:

According to a review of 61 studies of 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 effect.

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 percent of depressed patients, missing a night's sleep induce 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 judgement comparable to that induced by consuming several ounces of alcohol.

d.the dramatic shifts in mood connected with sleep and walefulness have not traced to partcular changes in brain chemistry.

e.depression returns in full force as soon as the patient sleeps for even a few minutes.

答案是E,大家看看吧~
