Hi Tammy and welcome to OCF.
The beginning of this disease can be so hard. You hear the news, go to specialists and learn words you never wanted to learn. You are thrusted into this new life head first (seriously) then the emotional part comes. He must continue his treatment and with the support of you and other family he can do it. I would highly suggest getting him to this site. When I found this site I realized I was not alone and that changed everything for me.
