摘　　要：目的探讨脑损伤患者失算症的错误表现和相关脑机制。方法对40例脑损伤患者(左脑20例、右脑9例、双侧11例)和48例年龄及教育年限匹配的正常成人进行EC301失算症标准化测验,对所得数据进行统计分析。结果脑损伤组的27个项目成绩和总分均低于对照组(P<0.05),左脑损伤组的数字序列、数字编码转换成绩和总分低于右脑损伤组(P<0.05);双侧脑损伤组、左脑损伤组和右脑损伤组的各项目成绩和总分两两比较均无统计学差异(P>0.05)。结论脑损伤患者存在数字加工和计算能力受损;左脑损伤患者的失算表现与失语既密切联系,又相互独立;视空间障碍与右脑损伤患者失算表现有关。Objective To investigate errors and mechanism of acalculia in patients with brain injury. Methods Forty patients with brain injury and forty-eight normal adults who were matched in age and years of education were tested with EC301 standardized battery. Patients were divided into the left-brain damaged （LBD） group （n= 20）, right-brain damaged （RBD） group （n=9） and bilateral brain damaged （BBD） group （n= 11）. The data of all subjects were statistical analyzed. Results Both total scores and scores of 27 out of 31 items were remarkable lower in patients than those in the normal control group （ P〈0.05）. The total scores and items scores for number sequences, numerical transcodings were significantly lower in LBD group than those in RBD group （ P〈0.05）. Total scores and each items score did not significantly differ between BBD group and LBD group, or between BBD group and RBD group （ P〉0. 05）. Conclusion The abilities of number processing and calculation are impaired in patients with brain injury. There is either association or dissociation in terms of performance of acalculia and aphasia in LBD patients. Visuospatial impairment is related to performance of acalculia in RBD patients.
