Analysis of the relationship between sleep disorder and cognitive impairment in the elderly and its related influencing factors

Objective To explore the relationship between cognitive impairment and sleep disorder in the elderly and analyze the influencing factors of cognitive impairment, so as to provide reference for improving sleep quality and cognitive function in the elderly.Methods One hundred and fifty-two seniors with insomnia in the Outpatient and Ward of the Second Department of Spermatology inthe Eighth Hospital of Shijiazhuang City from January 2016 to December 2017 were investigated by convenient sampling, and 150healthy volunteers with normal sleep were selected as normal group. The sleep quality and cognitive function of the elderly were assessed by Pittsburgh Sleep Quality Index (PSQI) and Montreal Cognitive Assessment (MoCA). Spearman correlation coefficient methodwas used to analyze the relationship between sleep disorders and cognitive impairment. Multivariate logistic regression was used to analyze the effects of different sleep disorders on cognitive impairment.Results The average PSQI score of 152 patients with sleep disorders was (14.67±1.68), and the average MoCA score was (16.79±3.89). The results of correlation analysis showed that the total score ofMoCA and its subitems were negatively correlated with the total score of PSQI. Multivariate logistic regression analysis showed that cognitive impairment was statistically different from the length of sleep, time of fall asleep and daytime dysfunction.Conclusions The incidence of cognitive impairment in the elderly with sleep disorders is increasing. Reasonable sleep time and falling asleep time can improve cognitive function and protect cognitive function; while daytime dysfunction and cognitive impairment interact with each otherand can lead to illness aggravate.
