Abstract:
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.
