Acalculia is defined as the inability to mentally manipulate numbers for simple calculations. It may occur in dementia, central nervous system (CNS) neoplasm, and stroke (Bermejo-Velasco and Castillo-Moreno, 2006). Lesions of the left parietal cortex are the principal cause. When acalculia occurs in stroke, it is generally associated with other deficits in speech, sensation, or motor function. We report the case of a 63-year-old male with a 1 day history of isolated acalculia that was found to have a left parietal lobe infarct with several smaller infarcts in the left occipital lobe. The diagnosis of stroke should be considered in all patients experiencing acute difficulty with mathematics, reading, or writing, even in the absence of other deficits.
失算症被定义为无法进行简单计算的心算能力丧失。它可能发生在痴呆症、中枢神经系统（CNS）肿瘤和中风中（Bermejo-Velasco 和 Castillo-Moreno，2006）。左顶叶皮层的病变是主要原因。当失算症发生在中风中时，它通常与言语、感觉或运动功能的其他缺陷相关。我们报告了一例 63 岁男性的病例，该患者有 1 天的孤立性失算症病史，发现左侧顶叶有梗死，左侧枕叶有几个较小的梗死灶。所有出现数学、阅读或书写急性困难的患者，即使没有其他缺陷，也应考虑诊断为中风。
