I am just so sorry you are going through this. But your brother has survived so much, he sounds like a very strong man. If he has come this far, and survived, I feel there is such excellent hope for his recovery. Please keep us updated; this must be so horribly stressful for you, and your family. I for sure, will pray for him and his continued progress to health.
Sending you a really big hug, Hon,
Lauren
