Even though I don't have TBI, I have been a caregiver. All the posts you received have offered some good advice. Write down anything unusual that occurs with his personality, so that when you go back to the therapy, you have that record. I know how hard is it to have patience. That is the best advise I can give you as a caregiver. Also take time some way some how for yourself during each day. The care giver, "you", need a space for yourself. I hope that you have family and friends near by to be in your corner. I hope your loved one recovers fully. Come back here any time to talk. NT will be here for you. I will keep your family in my prayers. ginnie
