The appearance of new onset accented speech after brain insult has been rarely reported. Stroke is often responsible for the development of what has been termed foreign accent syndrome (FAS). Foreign Accent Syndrome was initially described by Pick in 1919, and further elaborated on by Monrad-Krohn in 1947. Manifestations include disruption in segmental and prosodic elements of speech, which results in a listener's perception of the speech as foreign. In the majority of these rare cases, the patients present without having been exposed to the accent in the past. However, reports of a spoken accent in which the patient had significant previous exposure to in the past have been described. We report a case in which a woman developed a Germanic accent coinciding with the return of speech several days following an embolic left-hemispheric cortical infarction. The underlying neuroanatomical and pathophysiological explanations are reviewed. Additionally, the psychosocial consequences of this rare phenomenon are discussed.
脑损伤后新发明显口音的情况鲜有报道。中风常导致所谓的外国口音综合征(FAS)的出现。外国口音综合征最初由皮克于1919年描述,1947年莫拉德 - 克罗恩进一步阐述。其表现包括言语的音段和韵律元素紊乱,导致听者感觉言语带有外国口音。在这些罕见病例中,大多数患者此前并未接触过该口音。然而,也有患者过去曾大量接触过某种口音的相关报道。我们报告一例,一名女性在左侧半球栓塞性皮质梗死数天后恢复言语时出现了日耳曼口音。本文回顾了潜在的神经解剖学和病理生理学解释。此外,还讨论了这一罕见现象的社会心理后果。
