光照疗法在阿尔茨海默病中的应用进展

Advance in Light Therapy for Alzheimer's Disease(review)

光照疗法通过利用不同时长和不同强度的光线照射,对阿尔茨海默病患者的昼夜节律起到一定的调节作用。本文回顾国内外已有的研究,发现光照疗法在改善阿尔茨海默病患者的睡眠质量、认知功能和负性情绪等方面有一定的治疗效果,也越来越受到人们的关注;但也有部分研究发现光照疗法对阿尔茨海默病患者的睡眠和认知没有明显的改善作用。其中的具体机制尚未明确,未来还需要进一步研究。

With the use of light at different length and intensities, light therapy can regulate the circadian rhythm of the patients with Alzheimer's disease (AD). This paper reviewed the existing domestic and foreign researches, discovered that light therapy improved the sleep quality, cognitive function, and negative emotions, etc., of AD patients, and attracted more and more people's attention. However, some other studies found that light therapy did not significantly improve the sleep quality and cognitive function of AD patients. The specific mechanism is still unclear, and further studies are needed in the future.
