Do you think he is in pain? I know it made a huge difference when I was finally treated for chronic pain. I did not react well to any of the anti-depressant medication. In fact it made me much worse. Does he complain about pain a lot? Moan or whimper? Does not want to move because it hurts?
So sorry you and him are going through this. A brain injury is so devastating not only to the person but to their loved ones as well. You can come talk to us on the traumatic brain injury forum. I know the good people there have helped other caregivers. Good luck to you and you husband.
