Brain Oddities: Foreign Accent Syndrome

Brain oddities

Something about speaking a foreign language or having a mysterious accent always gives you cool points. I can’t speak for women in other countries, but I think I can speak for a majority of American women, a man (or woman) with a nice South African or Italian accent is immediately more attractive.

So, when I read about Foreign Accent Syndrome (FAS), I thought to myself, This doesn’t sound so bad, I could use some cool points. As it turns out, the chances of me or anyone I know developing this condition is slim to none. Foreign Accent Syndrome is a very rare condition affecting fewer than 100 people in the world. Potentially due to a number of different causes including stroke, migraine, allergic reaction, and anesthesia, FAS causes patients to adopt what sounds like a foreign accent. In most of the cases, the individual has never lived anywhere near the origin of the new found accent.

One of the recent notable cases is a woman from Newport, Oregon, who woke up from oral surgery speaking an Irish-sounding accent. At first, her oral surgeon was convinced that it was from post-surgery swelling. After several days, her accent did not disappear and she was diagnosed soon after with FAS. When asked if she would participate in the common speech therapy prescribed for these patients, she said no, she enjoyed her new accent. This was atypical; most people who suffer from FAS experience depression and anxiety.

As it turns out, scientists hypothesize that the condition isn’t technically a spontaneous foreign accent, but instead, a non-specific distortion of native language caused by damage to the motor-speech pathways in the brain. To the listener, the change in emphasis on certain vowels, consonants, and syllables may closely mimic a known foreign accent that has similar patterns. Specifically the left side of the prefrontal cortex, the motor cortex and the cerebellum are implicated in this disease. These findings give scientists further insight into what pathways control speech patterns.

Come to think of it, Madonna began speaking with a British accent after living in the UK for only one year. Could she be number 100?

  1. I have post concussion syndrome and now speak with what many tell me sounds like a Russian accent. I have been to the Doctors and they have never treated FAS and some have never heard of it. How do I get help?

  2. Hi Joy,
    I am not a doctor, so I can’t give you any medical advice, but I can point you in the direction of support groups and peer reviewed literature on the subject.
    The support groups for rare conditions can be extremely helpful emotionally. The peer-reviewed articles site people and researchers who are investigating this condition. You may be able to Google them and find contact info for them.
    Support Group:
    Peer Review Article from NIH: see reference #1 above.

  3. this is weird. i have to say i have had a lot of oral surgery/repeated maxillo facial well as tmj/joint replacement…all of which totally changed my roof of mouth and tongue position..muscles et. i also apparently have some nerve damage as i have a swallow type d/o to the right side and also have developed what seems to now be some nerve damage/changes…to face. i dont have a foreign accent however i do talk very very southern now most times…it is very odd but i thought it was just bc the muscles are so tight and the tongue i now keep it in roof of mouth. et. i did grow up in the south from 5th grade on however i never had a southern accent….when i would be on a plane et everyone would say you dont sound like you are from the i got married and moved to colorado in between some of my surgeries..and now am back in the south and when i am around my siblings i truly wonder if they wonder why i now speak so southern.. none of us do too much ..except my youngest sibling who was only small when we moved to the south. honestly im starting to wonder if this is kind of like what has happened to me. now everywhere i go people will say i can tell you are from the south and i try to explain to them is true..i am from north carolina..however…i never talked southern until after my jaw surgeries. mine seemed to have progressed and bc have had multiple surgeries…it seems at first just was hard to talk..muscles so i cant point to the exact surgery that caused it..however it seems to be after the tmj joint replacement et. its embarrassing..i dont mind talking southern…except that im not trying to do it and never did before….yikes….to me its very odd when people speak a foreign language as in french accent….after being totally just american…
