Dutch teenager forgot his native tongue after waking up from surgery and could only speak English
The 17-year-old boy, thought to be from Maastricht, was in hospital for routine surgery on his knee after a football injury. He awoke unable to speak his native tongue, and only communicated in English. The boy also couldn't recognise his own parents and thought he was in Utah (US). After 24 hours, the teenager 'spontaneously' recovered both his ability to speak and understand his native language after friends came to visit him. Medics believed he had foreign language syndrome an incredibly rare condition.
