Hey everyone

I don't post here often, so I'll explain why I'm on this site to give a little insight into my situation.

When I was 3 months old my dad threw me. This resulted in me being in a coma for 3 days, skull fracture, and all that stuff that goes along with that kind of injury...really the only confirmed issue from this is some peripheral vision loss on the right side.
However, I do have some coordination problems that are starting to severely affect my ability to function in martial arts the way that I should at my belt level. My question is, does anyone have any ideas on ways to improve coordination, specifically on one side of the body? (my right side is much worse)....and is it even possible to improve coordination that's been damaged by a brain injury? Especially since this was 19 years ago...has it been to long to bother trying to improve things? I really hope not...

Thanks
