Abstract:
Objective:To investigate the correlation between mild cognitive impairment(MCI)and sleep disorder in the elderly.Methods:A total of 220 elderly patients in our hospital from March 2018 to April 2020 were enrolled in this study, including 65 single amnestic patients, 97 multiple amnestic patients and 58 non-amnestic patients.The Pittsburgh Sleep Quality Index (PSQI)and Epworth sleepiness scale(ESS)were used to evaluate subjective sleep patterns.The quality of sleep were monitored and analyzed through polysomnography.The Spearman univariate correlation between MCI and sleep disorder was analyzed.Results:The average PSQI score of 220 patients was(17.1±3.9)points.The Spearman univariate correlation analysis showed the following results.(1)In the single amnestic group, MCI was positively correlated with the sleep quality, sleep time, daytime dysfunction, total PSQI score, arousal index and ESS score( rs=0.356, 0.324, 0.351, 0.412, 0.361 and 0.327, respectively, all P<0.05). (2)In the multiple amnestic group, MCI was positively correlated with the sleep quality, sleep time, sleep disorder score, hypnotic drug score, total PSQI score, arousal index, light sleep period and ESS score( rs=0.283, 0.323, 0.346, 0.401, 0.379, 0.412, 0.228, 0.251, all P<0.05). (3)In the non-amnestic group, MCI was positively correlated with the sleep time, hypnotic drug score, total score of PSQI, REM sleep disorder and light sleep period( rs=0.348, 0.307, 0.391, 0.355 and 0.228, all P<0.05). Conclusions:There are correlations between the MCI types and sleep disorders in the elderly, and different MCI types are associated with different factors on sleep disorder.
