Mild Brain Injury May Cause Chronic Sleep Trouble
04.04.07, 12:00 AM ET
WEDNESDAY, April 4 (HealthDay News) -- People who suffer mild brain injuries may be at increased risk for sleep disorders, researchers say.
Reporting in the April 3 issue of Neurology, researchers at the University of California, San Diego, assessed 42 people who complained of insomnia after they'd had a mild traumatic brain injury. Of those 42 patients, 15 (36 percent) had a circadian rhythm sleep disorder (CRSD) -- a problem with the timing of sleep.
Of the 15 patients with CRSD, eight had a "delayed sleep phase syndrome," including problems falling asleep and waking up; and seven had irregular sleep patterns.
"The frequency of sleep disorders in this study is considerably higher than the rate of these disorders among people attending sleep clinics for insomnia, which is seven to 10 percent," study author Liat Ayalon said in a prepared statement.
The findings highlight the need for improved diagnosis and treatment of circadian rhythm sleep disorders in patients who've had a mild brain injury and complain of insomnia.
"Misdiagnosis of these patients as insomniac may lead to prescription of medications, which help people fall asleep but don't help normalize the sleep-wake cycle," Ayalon said.
Since circadian rhythm sleep disorders are often associated with cognitive and psychological problems, proper treatment of these disorders may lead to improvements in other brain injury-related symptoms in these patients, the experts said.
"As many as 40 to 65 percent of people with mild traumatic brain injury complain of insomnia. This is concerning, since sleeping problems may exacerbate other brain injury symptoms such as headache, emotional distress, and cognitive impairment, making the rehabilitation process much harder," Ayalon said. 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领。 http://www.forbes.com/forbeslife/health/feeds/hscout/2007/04/04/hscout603227.html

轻微的脑损伤也许可以导致长期的睡眠障碍
WEDNESDAY, April 4 (HealthDay News) -- People who suffer mild brain injuries may be at increased risk for sleep disorders, researchers say.
Reporting in the April 3 issue of Neurology, researchers at the University of California, San Diego, assessed 42 people who complained of insomnia after they'd had a mild traumatic brain injury. Of those 42 patients, 15 (36 percent) had a circadian rhythm sleep disorder (CRSD) -- a problem with the timing of sleep.
星期三，4－04，（每日健康新闻）――研究人员说那些受到过轻微脑损伤的人出现睡眠障碍的可能性大大增加。来自San Diego加州大学的研究者们在4月3日的«神经病学»杂志上报导了他们的研究成果，在研究中他们评估了42位抱怨在受到轻微的创伤性脑损伤后出现失眠的患者。在这42位患者中，15位（36％）患有昼夜生物节律睡眠障碍――一种睡眠周期完全颠倒的睡眠障碍。
Of the 15 patients with CRSD, eight had a "delayed sleep phase syndrome," including problems falling asleep and waking up; and seven had irregular sleep patterns.
在这15位CRSD患者中，8位患有“睡眠时相延迟综合征”，它包括了入睡和觉醒的相关问题；还有7位有着不规律的睡眠-觉醒模式。
"The frequency of sleep disorders in this study is considerably higher than the rate of these disorders among people attending sleep clinics for insomnia, which is seven to 10 percent," study author Liat Ayalon said in a prepared statement.
研究作者Liat Ayalon在一份准备好的声明中说：“这项研究中睡眠障碍的发生率比那些因为失眠而去睡眠诊所寻求帮助的人患这些障碍的频率要高的多，因为诊所病人的患病率只有7％到10％。”
The findings highlight the need for improved diagnosis and treatment of circadian rhythm sleep disorders in patients who've had a mild brain injury and complain of insomnia.
这项发现强调了在那些受到过轻微脑损伤后抱怨失眠的病人中，我们需要提高对昼夜生物节律睡眠障碍的诊断和治疗。
"Misdiagnosis of these patients as insomniac may lead to prescription of medications, which help people fall asleep but don't help normalize the sleep-wake cycle," Ayalon said.
Ayalon说：“把这些病人误诊为失眠也许可以导致只给他们开一些处方药物，这些药物可以帮助他们入睡但是却不能使他们的睡眠－觉醒周期正常化。”
Since circadian rhythm sleep disorders are often associated with cognitive and psychological problems, proper treatment of these disorders may lead to improvements in other brain injury-related symptoms in these patients, the experts said.
