睡眠障碍对痴呆症患者及其家庭照顾者来说是个问题。这项交叉随机对照试验评估了一种创新的蓝白光疗法对17对痴呆症患者及其照顾者的影响。患有痴呆症的受试者接受了为期六周的蓝白光和对照（“红黄”光），中间间隔了四周的洗脱期。无论是活动记录法还是大多数自我报告的睡眠测量，痴呆症患者的差异都不显著。对于照顾者来说，睡眠和角色紧张都有所改善。未观察到视网膜光毒性的证据。六周的适度剂量蓝白光似乎可以改善护理人员的睡眠，但对痴呆症患者却没有效果。可能需要更大或更长的昼夜节律刺激来确定光是否是痴呆症患者的有效治疗方法。
Sleep disorders are problematic for persons with dementia and their family caregivers. This randomized controlled trial with crossover evaluated the effects of an innovative blue-white light therapy on 17 pairs of home-dwelling persons with dementia and their caregivers. Subjects with dementia received blue-white light and control (‘red-yellow’ light) for six weeks separated by a four-week washout. Neither actigraphic nor most self-reported sleep measures significantly differed for subjects with dementia. For caregivers, both sleep and role strain improved. No evidence of retinal light toxicity was observed. Six weeks of modest doses of blue-white light appear to improve sleep in caregivers but not in persons with dementia. Greater or prolonged circadian stimulation may be needed to determine if light is an effective treatment for persons with dementia.
