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.
Sexsomnia is a sleep disorder that, much like sleepwalking, compels the sufferer to engage in sexual activity while asleep. Identified in 2003, sexsomnia has since been cited to acquit defendants accused of sexual assault in British and Canadian criminal cases.
