That does sound very positive. Strangely, it may turn out that this stroke saves his life. He'll have no access to street drugs, get stable on his psychiatric medications, and physically he's improving quickly for how serious his condition was. Fingers crossed and prayers said.
Jabber has a nephew who basically blew himself up. (He's not a terrorist, just an idiot; it's a long story). He lost one arm below the elbow and most of his other hand as well - and very nearly died. His mother credits that injury with saving him. Sometimes things happen for the best, odd as it seems at the time.
I hope you are handling things well and taking care of yourself.
