目的探讨左、右大脑半球脑梗死患者失算症的特点和机制.方法选取56例脑梗死患者作为脑梗死组,其中左脑梗死34例(左脑梗死组),右脑梗死22例(右脑梗死组)；另选取56例年龄及受教育年限均与脑梗死组相匹配的健康成人作为对照组.对脑梗死组和对照组进行EC301数字加工和计算量表的中文修订版(EC301-CR)检测,对所得数据进行统计分析.结果脑梗死组EC301量表的各亚项评分均低于对照组,除视觉、听觉数点数2个亚项外,其余30个亚项评分差异有统计学意义(P＜0.05).左脑梗死组的倒数、非数字序列、数字阅读、听写数字、数字转化(汉字阿拉伯数字相互转换)、心算(听觉、视觉)和笔算(加减乘除)、常识数字估计及常识数字大小判断等14项评分低于右脑梗死组(P＜0.05).左脑梗死组失语症患者除数点数外各亚项评分均低于非失语症患者(P＜0.05).结论脑梗死患者可导致数字加工和失算症,左脑梗死患者较右侧脑梗死患者严重,合并失语症者失算症更严重.

Objective To investigate errors and the mechanism of acalculia in patients with left or right hemisphere cerebral infarction.Methods Fifty-six patients with single hemisphere cerebral infarction and 56 normal adults who were matched in age,sex and years of education were tested with EC301-CR.The patients were divided into a left hemisphere cerebral infarction group(n =34)and a right hemisphere cerebral infarction group(n =22).Results The scores on 30 out of 32 EC301-CR items were significantly lower among the patients than in the normal control group.Scores on 14 EC301-CR items were significantly lower in the left hemisphere group than in the right hemisphere group.In the left hemisphere group the item scores of aphasia patients were significantly lower than those of no-aphasia patients except on digit identity.Conclusion Mathematical processing and calculation were impaired in patients with single hemisphere cerebral infarction.Calculation was significantly worse among left hemisphere patients compared with right hemisphere cerebral infarction.There was a highly significant correlation between acalculia and aphasia.
