I guess with my role, I don't think you've answered any ?s that I would naturally ask when faced with a tough situation like this. Where is this case manager from? A state agency? Is your mom receiving social security or disability? Is your family financially stable for a private pay situation? Is your mom on medicaid/care?
What was the severity of the stroke? Does she have the ability to function on her own at all? Is she at home with you/others/on her own, or is she involved in a group setting? What are your mom's wishes? DNR status? is hospice an option? No, hospice is not a "place or organization to go to to die", I have seen them help MANY people. I guess if I could answers to those to start, I might be able to help you, if not I truly wish you the best.
