A total of 24 patients harboring arteriovenous malformations (AVMs) in either the dominant hemisphere (n = 12) or the nondominant hemisphere (n = 12) were examined neuropsychologically. When compared with 24 matched normal control subjects, the AVM patients demonstrated differential degrees of impairment in verbal or visuospatial processing, depending on whether the lesion involved the dominant or nondominant hemisphere. As predicted, most compelling were the findings of cognitive deficit associated with the hemisphere contralateral to the AVM relative to matched normal control subjects. Evidence of higher cortical dysfunction contralateral to the residing AVM is discussed in the context of cerebrovascular steal.
对总共24例患有动静脉畸形（AVM）的患者进行了神经心理学检查，这些患者的病变分别位于优势半球（n = 12）或非优势半球（n = 12）。与24名匹配的正常对照受试者相比，AVM患者在言语或视觉空间处理方面表现出不同程度的损伤，这取决于病变是累及优势半球还是非优势半球。正如所预测的那样，与匹配的正常对照受试者相比，与AVM对侧半球相关的认知缺陷的发现最为引人注目。在脑血管盗血的背景下讨论了与现存AVM对侧更高皮质功能障碍的证据。
