My father has ALS, diagnosed November 2006. We visited (edited content by AL) during the last 2-weeks for stem cell transplants. It was an outstanding experience, far surpassing our best hopes. It is too soon to know how well the treatment will work, but without question, his energy and strength is better than when we left.
I have valid reasons for editing your post. Contact me by Private Message if that is a problem for you. If you could come back in 3 months and tell us how your father is doing we'd like to hear of a success story.
