Permanent “foreign accent” after cyclosporine encephalopathy in a liver transplant patient

TLDR: The composite features of patients with FAS are not characteristic of dysarthria or aphasia and partially resemble patients who have speech apraxia.

Abstract: Foreign accent syndrome (FAS) is a speech disorder that leads listeners to perceive the patient as having a foreign accent. The cardinal feature of FAS is prosody change, with variation in accent, intonation, and rhythm. Less frequently, phonetic changes with normal prosody may be detected. The composite features of patients with FAS are not characteristic of dysarthria or aphasia and partially resemble patients who have speech apraxia. Patients with FAS are often unfamiliar with the foreign language and often seem unaware of the disturbance, even though their ability to discriminate foreign accents is spared.
