Pretty much Piglet. I am wondering whether the diffuse agitation our brains suffer developing PTSD, is actually counter balanced with the abnormal reaction forced upon the brain that training yourself to be ambidextrous has. Both affect the right and left hemispheres in abnormal ways that our brains are not normally meant to function, so this is what leads me to possibly think it could have some merit. Maybe it does, maybe it doesn't.

I don't believe that the fact alone off training oneself to be ambidextrous could lessen the symptoms or cure PTSD, but I think it just may have merit in the sense that doing something that requires the self training to be ambidextrous in one area possibly, could have enough effect on the left and right brain hemispheres to possibly keep PTSD symptoms at bay! If that means one has to continuely practice their learnt skill throughout their life to ensure all symptoms remain null, and the brain is functioning in a more normal counterbalanced manner, then hey... I think only good could come off it for the sufferer themselves.

Hell, training yourself to kick a football equally left or right footed, is much more appeasing to keep symptoms at bay than taking medications that need to be constantly changed, constantly weined off and regular increases as the body develops immunity to them. I think an open minded physician should take this information and run with it, see what happens, put a few different spins on it, and hey, at the end of the day, if it doesn't work, then their at no lesser loss than they currently are now.
