Abstract:
Objective To analyze the effect of stroke duration on the cognitive function in the elderly population in Beijing.Methods Based on the Research Project of Beijing Chronic Disease Combined with Common Elderly Syndrome Community Management Practices,a cross-sectional study was used.From July 2013 to December 2014,the old population in 4 districts and a county (Xicheng District,Fangshan District,Tongzhou District and Yanqing County) in Beijing were sampled with the multi-stage,randomized and stratified sampling.A total of 3 024 subjects were enrolled in the study.The data were obtained from the questionnaires and clinical examinations.Mini-Mental State Examination (MMSE) was used as the evaluation index of cognitive function.The subjects were divided into either a normal cognitive function group (MMSE>26,n=1 878) or a cognitive impairment group (MMSE≤26,n=1 146) according to the MMSE scores.A multiple logistic regression model was used to analyze the effects of hemorrhagic stroke,ischemic stroke,and asymptomatic stroke,as well as disease duration on cognitive function.Results After adjusting for the confounding factors,such as sex,age,educational level,marriage,smoking,and alcohol consumption,the risks of occurring cognitive impairment in patients with hemorrhagic stroke in stroke duration for 1-3,4-10 and >10 years were OR 3.019 (95％CI 0.974-9.361,P=0.056),8.652 (95％CI 2.924-25.601,P<0.01) and 1.104 (95％CI 0.311-3.920,P=0.879) times of those without occurring stroke population;the risks of occurring cognitive impairment in patients with ischemic stroke in stroke duration for 1-3,4-10 and >10 years were 1.000 (95％CI 0.636-1.571,P=1.000),1.874 (95％CI 1.231-2.853,P=0.003),2.439 (95％CI 1.386-4.291,P=0.002) times of those without occurring stroke population.Stroke duration for 4-10 years in patients with hemorrhagic stroke and stroke duration for 4-10 and >10 years in patients with ischemic stroke were all the risk factors for occurring cognitive dysfunction.Conclusion For patients with stroke,stroke duration or long-term effects has a certain impact on cognitive function.
