My husband traveled to China for a treatment with glial cells injected into his brain. He did see immediate results then nothing. He survived 5 years after treatment, but got progressively worse. When you are first put into this situation, you are willing to do anything to treat the disease as we were. Since no follow up was available, we do not know where he would have been without the treatment. I think the travel and China experience was hard on his body. He was the youngest one there and the one with the least amount of symptoms. He did see people walk who had been unable, and he got some hand strength back, but without further treatment, it only progressed.
