Sleep disorders are common diseases with various dys-function during sleep-wake process, including difficulty falling or staying asleep, falling asleep at inappropriate times, excessive total sleep time, or abnormal behaviors associated with sleep. Sleep disorders can lead to the deposition of amyloid beta protein ( Aβ) by affecting the normal metabolism of amyloid beta protein in the brain. Patients with Alzheimer’s disease ( AD) often suffer from sleep disorders, and its pathology always results in more se-vere sleep disorders, which leads to a risk of cognitive impair-ment and hypofunction. Sleep disorders could interact closely with AD, forming a positive feedback loop, which causes serious damage to the body health. This review summarized the current research about sleep disorder in the onset of AD and the current status of medication.%睡眠障碍系指睡眠-觉醒过程中表现出来的各种功能障碍,包括各种原因导致的失眠、过度嗜睡、睡眠呼吸障碍以及睡眠行为异常。睡眠障碍影响脑内β淀粉样蛋白( amy-loid beta protein, Aβ)的正常代谢,加速Aβ沉积。阿尔采末病(Alzheimer's disease, AD)患者常伴有睡眠障碍,AD患者的睡眠障碍会随着AD病情的发展而加重,对认知损伤、功能衰退都有一定影响。睡眠障碍与AD相互作用,形成正反馈环,严重危害机体健康。该文结合近来研究结果,对目前睡眠障碍与AD的相关研究及AD睡眠障碍药物治疗现状进行综述。
