If you have suffered TBI I highly suggest getting neurofeedback training to try and repair any possible damage caused to the brain by the injury. It is a very powerful tool to change the structure of your brain. Just make sure you find a specialist that can accurately create a profile for your particular set of circumstances and creating a special training program for that. I almost signed up for a borderline scam, but luckily found the leading expert in the field (She essentially pioneered Neurofeedback training).
