Good link!! But you left some parts out. I'm sure you didn't mean to:

Is there any treatment?

Once an individual is out of immediate danger, the medical care team focuses on preventing infections and maintaining a healthy physical state. This will often include preventing pneumonia and bedsores and providing balanced nutrition. Physical therapy may also be used to prevent contractures (permanent muscular contractions) and deformities of the bones, joints, and muscles that would limit recovery for those who emerge from coma.

Exactly.

I still don't know which way I would go.

Does her family keep her alive, only to lose her years later from multiple organ failure, amputation due to decubitus, difficulties in dehydration and nutrition, respiratory failure?...

The ONLY thing I am sure of is that I thank God I have not yet been faced with this decision for a loved one. God made that decision for us over the course of 9 months.
