背景和目标。左半球的损伤会导致失语，而右半球的外侧裂周围区的损伤会导致情感性言语韵律（情感性言语韵律）的损伤。左侧内侧额叶损伤与言语流畅性降低相关，但理解和重复相对完整（经皮质运动性失语），但与右侧内侧额叶损伤相关的持续情感韵律缺陷尚未被描述。方法.我们评估了一位七年前患有右额内侧脑梗死的男性的韵律。结果虽然命题语音表达是正常的，包括句法韵律，患者在表达情感的韵律受损。他对韵律的理解和重复也受到了损害，但程度不及表达。结论.右内侧额叶病变可诱导情感性的声音缺失，主要损害表达。爱思唯尔公司出版
Background and objectives. Whereas injury to the left hemisphere induces aphasia, injury to the right hemisphere's perisylvian region induces an impairment of emotional speech prosody (affective aprosodia). Left-sided medial frontal lesions are associated with reduced verbal fluency with relatively intact comprehension and repetition (transcortical motor aphasia), but persistent affective prosodic defects associated with right medial frontal lesions have not been described. Methods. We assessed the prosody of a man who sustained a right medial frontal cerebral infarction seven years prior. Results. While propositional speech expression was normal including syntactic prosody, the patient was impaired at expressing emotions using prosody. His comprehension and repetition of prosody were also impaired but less so than expression. Conclusions. Right medial frontal lesions can induce an affective aprosodia that primarily impairs expression. Published by Elsevier Inc.
