ABSTRACT
Objective To investigate the evolution of cognitive function and its influence factors,so as to provide evidence for guiding treatment of cognitive impairment after stroke.Methods A total of 98 cases of patients with stroke admitted in the First and Second Affiliated Hospital of Medical College of Xi'an Jiaotong University and Shaanxi Provincial People's Hospital between April and September 2009 were enrolled and recruited.Mini-mental state examination(MMSE) and Montreal cognitive function rating scale (MoCA) were adopted to assess the evolution of cognition at acute phase( within 2 weeks),6 weeks,and 12 weeks after stroke among patients within 2 weeks after onset,questionnaire score≤56,without aphasia and consiousness disturbance and at least one side of upper extremities muscle force ≥ grade 3.Results When using MMSE scale as criteria,the incidence of cognitive impairment was 24.5% at acute phase,12.1% at 6 weeks and 9.9% at 12 weeks after stroke,while the incidence was 86.8%,68.2%,and 38.0% respectively when using MoCA scale as criteria.The scales of MMSE and MoCA were increased and the incidence of cognitive impairment was decreased within 12 weeks after stroke.Logistic regression analysis indicated that,advanced age( β = -0.124 ),hypertension ( β = -3.705 ),low education level ( β = 0.560 )and depression after stroke ( β =4.613 ) were related with cognitive impairment after stroke ( all P values <0.05 ); low education level ( β = 0.710 ),coronary heart disease ( β = -3.649 ),elevated total cholesterol (TC) ( β = -3.361 ) and low density lipid cholesterol (LDL-C) ( β = - 5.833 ),and depression ( β =-3.612) delayed recovery of cognition after stroke.Conclusions The cognitive function improves and the incidence of cognitive impairment lowers as the time goes on within 12 weeks after stroke.The factors that may affect the improvement of cognitive function include low educational level,coronary heart disease,elevated TC and LDL-C,and post-stroke depression.
