I understand what you're saying with spelling. I had a bit of a problem afterward. Although I don't know how much of it was injury related because I never used proper puntuation before. I'd say your when I should have said you're etc. My main thing is I have to correct spelling and grammar mistakes just part of my personality. However I did find after my concussion I read a lot of books that helped. Also another thing I found to help tremendously is changing my diet eating healthy and drinking between 7-10 bottles of water per day. Thanks for your advice best of luck with your recovery!!
