OBJECTIVE
The authors evaluated the effects of bright-light therapy on daytime sleep among nursing home patients with dementia.
METHODS
Eleven patients with sleep/wake disturbances received 2 hours/day of morning bright-light exposure for 2 weeks. Sleep was measured with actigraphy and nursing staff diaries.
RESULTS
Daytime sleep decreased significantly in the period from rising time to 3:00 P.M. with bright-light treatment. Treatment effects did not last into the 16-week post-treatment period.
CONCLUSIONS
Bright light exposure was effective in reducing daytime sleep in nursing home patients with dementia; this finding is possibly related to bright light's acute alerting effects.
目的
作者评估了强光疗法对患有痴呆症的疗养院患者日间睡眠的影响。
方法
11名有睡眠/觉醒障碍的患者每天上午接受2小时强光照射，持续2周。通过活动记录仪和护理人员日记来测量睡眠情况。
结果
在强光治疗期间，从起床时间到下午3点，日间睡眠显著减少。治疗效果在治疗后16周内未持续。
结论
强光照射对减少患有痴呆症的疗养院患者的日间睡眠有效；这一发现可能与强光的急性警觉作用有关。
