Foreign accent syndrome following traumatic brain injury.

Foreign accent syndrome (FAS) is a very rare disorder, caused by lesions of the dominant brain hemisphere and defined as a loss of normal phonetic contrast when using the mother language. The pronunciation is perceived by native speakers as compromised by a foreign accent. This study reports about a 35-years old woman, with a FAS following a brain injury with a traumatic left temporal haemorrhage, who experienced excellent remission after 2 years.
