脑损伤患者的执行功能损害

摘要：Abstract:Objective To investigate the characteristics of executive function in patients with brain injury. Methods From March 1st, to June 30th,2015,44 patients with brain injury were investigated with Wisconsin Card Sorting Test (WCST), the indexes including Responses Answer, Categories Completed, Correct Responses, Errors Responses, Trials to Complete First Category, Percent Conceptual Level Respons-es Percentage, Perseverative Responses Errors, Nonperseverative Responses Errors, Failure to Maintain Set, and Learning to Learn. Results The abnormal rates were the most in Nonperseverative Responses Errors and Percent Conceptual Level Responses Percentage (61.36%), and then in Responses Answer/Categories Completed/Correct Responses (59.09%), Correct Responses (43.18%), Trials to Complete First Category (38.64%), Perseverative Errors (29.51%), Learning to Learn (25.00%), and Failure to Maintain Set (9.09%). The patients with trau-matic brain injury were different from those with stroke in Responses Answer, Errors Responses, Perseverative Responses Errors, Catego-ries Completed, Percent Conceptual Level Responses Percentage, and Learning to Learn (Z>2.444, t>2.156, P<0.05). The patients injured in frontal lobe were different from those in other areas in Perseverative Responses Errors (t=2.595, P=0.015). Conclusion Executive function damaged generally in patients with brain injury, which related to concentration, abstract, shifting attention, working memory, etc. The frontal lobe damage may associate with the disorder of shifting attention
