We report three cases of effortful echolalia in patients with cerebral infarction. The clinical picture of speech disturbance is associated with Type 1 Transcortical Motor Aphasia (TCMA, Goldstein, 1915). The patients always spoke nonfluently with loss of speech initiative, dysarthria, dysprosody, agrammatism, and increased effort and were unable to repeat sentences longer than those containing four or six words. In conversation, they first repeated a few words spoken to them, and then produced self initiated speech. The initial repetition as well as the subsequent self initiated speech, which were realized equally laboriously, can be regarded as mitigated echolalia (Pick, 1924). They were always aware of their own echolalia and tried to control it without effect. These cases demonstrate that neither the ability to repeat nor fluent speech are always necessary for echolalia. The possibility that a lesion in the left medial frontal lobe, including the supplementary motor area, plays an important role in effortful echolalia is discussed.
我们报告了三例脑梗死患者出现的费力模仿言语的病例。言语障碍的临床表现与1型经皮质运动性失语(TCMA,戈德斯坦,1915年)相关。患者说话总是不流畅,缺乏言语主动性,存在构音障碍、韵律障碍、语法缺失,且费力增加,无法重复超过四或六个单词的句子。在对话中,他们首先重复对他们说的几个单词,然后产生自发言语。最初的重复以及随后同样费力产生的自发言语可被视为减轻的模仿言语(皮克,1924年)。他们总是意识到自己的模仿言语,并试图控制但无效果。这些病例表明,模仿言语并不总是需要重复能力或流畅言语。本文讨论了包括辅助运动区在内的左侧内侧额叶病变在费力模仿言语中起重要作用的可能性。
