Hi and welcome to NeuroTalk! I'm so sorry for all that your family is going through. I've posted the link to the Post Concussion Syndrome forum in case you haven't found it......
http://neurotalk.psychcentral.com/forum92.html. I'm sure someone there will be able to relate to your situation.
Sounds like you've had quite alot to deal with and I hope that this board will provide you with some hope and relief. I'm glad you found us. Please let us know if you have any questions.
