Foreign Accent Syndrome

It's not a very common disease in which people who have suffered strokes or other injuries adopt a new accent.
For example, Tiffany Roberts of Florida suffered a stroke and then began speaking with an English accent. She even adopted Anglicisms such as ‘bloody’ and ‘loo’. Ms Roberts had never been to Great Britain, and was not a fan of British television shows. Perhaps the oddest case concerned a Norwegian woman who had fallen into a coma after having been hit by shrapnel during an air raid in 1941. When she woke up, she spoke with a thick German accent. She was then ostracised by her neighbours.
