Sadly, MRIs just aren't subtle enough to image the damage to your brain's tiny - but vitally important - little axons. Short of detecting a brain bleed, the vast majority of TBI patients have "normal" MRIs. Concussed athletes who had "normal" MRIs during their playing days have been found to have very serious brain injuries when autopsied.

Have you had a neuro-psychological exam? That remains the best way to identify TBI deficits and target cognitive and vocational therapy.

While it's true that there is no "cure" for TBI, there are things you can do to make your life more bearable. There are cognitive therapies that can help. Eat a healthy diet and avoid alcohol and caffeine. Seek help for your emotional struggles. Your local Brain Injury Association can be a great source of support and practical information on things like health care professionals and techniques to work around your deficits.

You're not alone.
