Teen wakes up after coma fluent in a foreign language

Reuben Nsemoh has been struggling to adjust after his concussion, and it's not just because he can't concentrate -- the 16 year old can't stop speaking a foreign language.

According to CNN, the teen from suburban Atlanta fell into a coma after he was kicked in the head playing soccer last month.

When he regained consciousness, he did something he could never do before -- he spoke Spanish like a native.

Reuben's parents say his English is coming back now, and he's beginning to lose his Spanish fluency.

Though it seems like something that would only happen in a cartoon, Reuben actually has a serious condition called Foreign accent syndrome.

According to UT Dallas, patients with FAS have serious brain injuries that change their speech patterns and give them different accents.

The first case was reported in 1941 when a woman from Norway was injured by shrapnel in a German bombing run. She started speaking in a German accent.

Since then, the disorder has only appeared a few dozen times.

According to CNN, police found a Navy veteran unconscious in California. When he woke, he had completely forgotten everything about his life, and he only spoke Swedish.

"It's an impairment of motor control," Dr. Karen Croot, one of the few experts in foreign accent syndrome, told CNN a few years ago.

"Speech is one of the most complicated things we do, and there are a lot of brain centers involved in coordinating a lot of moving parts. If one or more of them are damaged, that can affect the timing, melody and tension of their speech."
