Can trauma remove the power of speech?

Question

Can shock or trauma render someone speechless and is it temporary? how can someone be brought out of it?
Any help I'd be so appreciative. Thank you.

Answer 1

I wouldn't call it an actual physical condition as such, but I think sometimes people lose the /will/ to speak. I also think there was some evidence of soldiers in the first world war being silent after the war, so yes, I think shock and trauma can take away speech. Whether it's voluntary on the part of the person or not, I couldn't tell you.
