摘要

外语综合征(Foreign Language Syndrome, FLS)是一种罕见的神经精神疾病,其特征是突然、不自觉地使用非母语,同时丧失或抑制母语。与外国口音综合征(FAS)不同,FLS通常在麻醉、脑损伤或心理压力后急性发作。虽然神经影像学通常没有显示结构性病理,但双语语言控制系统的功能脱节已经被假设。病例报告表明,神经系统紊乱(如短暂的皮质功能障碍)和精神机制(包括分离和转化现象)都是造成这种现象的原因。本文综述了FLS的临床特征、诊断策略、神经认知模型和精神病学解释。它强调了多学科评估和治疗的重要性,并概述了预后模式。需要纵向随访,功能影像学研究和集中的病例数据库强调,以更好地了解病理生理和临床管理的这种神秘的综合征。

Foreign Language Syndrome: Neurological and Psychiatric Aspects.

Foreign Language Syndrome: Neurological and Psychiatric Aspects.

Foreign Language Syndrome (FLS) is a rare neuropsychiatric condition characterized by the sudden, involuntary use of a non-native language, with concurrent loss or suppression of the native language. Distinct from Foreign Accent Syndrome (FAS), FLS often arises acutely following anesthesia, brain injury, or psychological stress. Although neuroimaging typically reveals no structural pathology, functional disconnection within bilingual language control systems has been hypothesized. Case reports suggest contributions from both neurological disruptions-such as transient cortical dysfunction-and psychiatric mechanisms, including dissociation and conversion phenomena. This review synthesizes the clinical features, diagnostic strategies, neurocognitive models, and psychiatric interpretations of FLS. It emphasizes the importance of multidisciplinary evaluation and treatment and outlines prognosis patterns. The need for longitudinal follow-up, functional imaging studies, and centralized case databases is highlighted to better understand the pathophysiology and clinical management of this enigmatic syndrome.
