ABSTRACT

Objective To analyze the characteristics of the non-language-based cognitive function in patients with aphasia after stroke.Methods Thirty patients of the first infarction with aphasia and thirty stroke patients without aphasia were recruited.The aphasia deficits in patients were evaluated using the Aphasia Battery of Chinese(ABC).The non-language-based cognitive assessment scale (NLCA) was applied to analyze the cognitive function in the two groups.The stroke aphasic depression questionnaire hospital version (SADQ-H)was applied to analyze the depression in the two groups.Results The score in NLCA of the aphasia group was significantly lower than that of control group((50.01± 14.01)vs(66.13±5.95),P＜0.01).There was high correlation between the total and sub-scores of NLCA and ABC in both groups(P＜0.01,P＜0.05).The score in SADQ-H of the aphasia group was significantly higher than that of control group((21.83±7.37)vs(16.13±5.84),P＜0.01).The total score for the aphasia patients shown by the SADQ-H was negatively related with the total score of the NLCA(r=-0.468,P＜0.05).Conclusion There is non-language-based cognitive dysfunction in patients with aphasia after stroke,and the severity of depression affects cognitive function.
