Abstract: ObjectiveTo explore the relationship between cognitive impairment after stroke and possible factors.MethodsThe stroke patients being in hospital from 1977 to 2004 were evaluated with (scale of elderly cognitive function, SECF), the self-rating depression scale (SDS), the self-rating anxiety scale (SAS) and the ability of daily living (ADL). 236 cases with SECF≤90 were considered as cognitive impairment and retested with 4 scales mentioned above 2 months later. Gradual regression analysis was applied, one factor was taken as dependent variable selected from sex, age, education, course of disease, etiological factor, hemiplegia side, SECF1, SECF3, ADL1, ADL3, SAS1, SAS3, SDS1, SDS3, while others were taken as independent variable.ResultsAfter two months treatment in hospital, scores of SECF and ADL of patients improved, SAS and SDS reduced significantly (P=0.000). The proportion of female and cerebral infarction in aged patients was higher and scores of ADL reduced significantly (P<0.05). The SDS scores of patients with long course of disease before hospitalization were higher; there was a small improved extent for ADL ( P<0.05). SAS scores of patients with high ADL were low (P=0.028).ConclusionEarly residential rehabilitation can improve ADL function and reduce depression of stroke patients.
