i was poisoned in '90 and suffered severe brain damage. i lost almost all abilities excect my ability to talk, which saved my bacon numerous times.
i have regained over 75 IQ points, tho not evenly over all areas, by endless practice and the use of a sound therapy that helps the brain make new connections. it is called Binaural Beat , and uses stereo sound to stimulate the brain. perhaps it will help you. it is not a quick-fix, i used it for 7 years every day, twice a day. you can find the therapeutic tracks at
CenterPointe.com, or you can just search for sound tracks online (to see if you like it).
the brain is a very plastic (changeble) thing, and it's never too late to help it along. i wish you the very best in adding to your brain functions, and learning to operate with what you have~
