【Abstract】Objective To study the correlation between sleep quality changes and cognitive function in elderly patients with chronic insomnia. Methods A total of 120 elderly patients with chronic insomnia admitted to our hospital from August 2019 to August 2020 were selected as the observation group, and 120 elderly patients with healthy physical examination during the same period were selected as the control group. The Pittsburgh Sleep Index (PSQI) score and the Montreal Cognitive Function Assessment Scale (MoCA) score were compared between the two groups, and the correlation between PSQI score and cognitive function in elderly patients with chronic insomnia was analyzed. Results The sleep efficiency, time to fall asleep, day dysfunction, sleep time, sleep disturbance, sleep quality, sleep medication and total score in the observation group were higher than those in the control group (P<0.05). The observation groups abstraction, attention, language, visual function and executive function, delayed recall, naming, orientation and total scores were lower than those of the control group (P<0.05). According to Pearson test, sleep quality, sleep time, sleep efficiency, sleep time score and total PSQI score were negatively correlated with visual and executive function scores (P<0.05); sleep efficiency, daytime dysfunction score, and total PSQI score and nomenclature The score was negatively correlated (P<0.05); the daytime dysfunction score and the total PSQI score were negatively correlated with the attention score (P<0.05); the total PSQI score was negatively correlated with the language score (P<0.05); sleep efficiency, falling asleep Time score and total PSQI score were negatively correlated with abstract score (P<0.05); sleep time, day dysfunction, sleep disorder score, and PSQI total score were negatively correlated with delayed recall score (P<0.05); sleep medication, falling asleep Time, sleep quality score and total PSQI score were negatively correlated with orientation score (P<0.05); sleep time, sleep quality, sleep medication, day dysfunction, time to fall asleep, sleep efficiency score were negatively correlated with MoCA total score (P<0.05).Conclusion There is a certain correlation between changes in sleep quality and cognitive function in elderly patients with chronic insomnia.
