Doctors have come across some baffling day-to-day ailments, but few conditions are as strange as these 20 disorders, which range from biological to psychological to cultural in nature.Foreign Accent Syndrome
Foreign accent syndrome (FAS) is a speech disorder that causes sudden changes in speech pattern, intonation and pronunciation so that the victim is perceived to speak with a "foreign" accent. FAS usually results from severe trauma to the brain, such as a stroke or head injury, and typically develops within one or two years of the injury. Of the 50 to 60 cases that have been verified since 1941, only a few FAS sufferers regained their normal speech pattern, although some experienced success through speech therapy.
