Acute Aphasia

Multiple reports have described patients with disordered articulation and prosody, often following acute aphasia, dysarthria, or apraxia of speech, which results in the perception by listeners of a foreign-like accent. These features led to the term foreign accent syndrome (FAS), a speech disorder with perceptual features that suggest an indistinct, non-native speaking accent. Also correctly known as psuedoforeign accent, the speech does not typically match a specific foreign accent, but is rather a constellation of speech features that result in the perception of a foreign accent by listeners. The primary etiologies of FAS are cerebrovascular accidents or traumatic brain injuries which affect cortical and subcortical regions critical to expressive speech and language production. Far fewer cases of FAS associated with psychiatric conditions have been reported. We will present the clinical history, neurological examination, neuropsychological assessment, cognitive-behavioral and biofeedback assessments, and motor speech examination of a patient with FAS without a known vascular, traumatic, or infectious precipitant. Repeated multidisciplinary examinations of this patient provided convergent evidence in support of FAS secondary to conversion disorder. We discuss these findings and their implications for evaluation and treatment of rare neurological and psychiatric conditions.

Abstract Purpose: The sudden emergence of a foreign accent in an individual's native language has been described in the literature for over 60 years. In one of the most famous cases, the terms prosody and dysprosody first were introduced to the literature. The purpose of this paper is to summarize the prosodic changes seen in the foreign accent syndrome (FAS) and to review its etiology and clinical course. Method: Case studies were reviewed, with an emphasis on information about clinical presentation and course and on speech changes affecting stress, rate, duration, and intonation. Results and Conclusions: In the majority of published cases with FAS, there has been documented focal brain injury in the left cerebral hemisphere, and the foreign accent has emerged after a period of recovery from muteness, nonfluent aphasia, and/or motor speech disorder. In other cases, a psychogenic etiology has been established or suggested. Stress, rate, and duration changes are similar to those seen in nonfluent aphasia and apraxia of speech, whereas intonation changes are more specific to the foreign accent presentation. Information about recovery and psychosocial consequences of the accented speech is sparse and these areas are in need of further study. In particular, there is a need for detailed and clinically oriented case studies with longitudinal follow-up.

ABSTRACT. Foreign accent syndrome (FAS) is an extremely rare disorder, with 112 cases described until 2019. We compare two cases of the foreign accent syndrome in native speakers of Brazilian Portuguese in its classic form (FAS) and psychiatric variant (FALS). Two cases were analyzed: (1) a right-handed, 69-year-old man, with a prior history of stroke, and (2) a right-handed, 43-year-old woman, diagnosed with schizophrenia. They were evaluate for language and speech, including the speech intelligibility. Both patients had speech impairments complaints, similar to a new accent, without previous exposure to a foreign language. However, the onset of the speech disorder was sudden in case 1 and insidious and with transient events in case 2, with speech intelligibility scores of 95.5 and 55.3% respectively. Besides neurologic impairment, the clinical presentation of FALS was extremely severe and differed to that expected in FAS cases, in which speech intelligibility is preserved.
