Foreign Accent Syndrome

Background Foreign accent syndrome (FAS) consists of a speech rhythm disorder different from dysarthia or aphasia. It is unusually met in multiple sclerosis (MS). Objective We report a case of FAS as an initial symptom of a MS. Methods A right-handed French woman developed an isolated German foreign accent. Brain magnetic resonance imaging (MRI), SPECT and analysis of CSF were performed. Results Brain MRI revealed a large hypersignal on T2-weighted images in the left prerolandic white matter. Single photon emission computed tomography showed a right prerolandic hypoperfusion. Unmatched oligoclonal bands in cerebrospinal fluid and occurrence of new abnormal hypersignals on the following MRI led us to diagnose MS. Conclusion FAS may be the first symptom of MS. It could result from extensive disturbances of brain function involving the right hemisphere.

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.
