valenz,
I want to welcome you to the HealthBoards, I hope someone here can help you with your specific question.
I had 4 strokes when I was 43, too. That was 5 years ago now. In he last few years, I have regained most of my abilities back. I want to share with you the tremendous possibility for your mom to get much better, over time. I also had therapy 3 times a week, outpatient. I commend you for seeking the best treatment for your mom, but with time, and a lot of sleep, the brain does some amazing healing.
I wish you the best...
