This has been posted previously. Stem cell progress has been discussed in other threads. Use the Search link up top. In brief, there are no stem cell trials currently recruiting; there is hope for future use, but probably no other trials for a year or two. It is a slow process.
That link is to what I believe is discussed in unapproved ALS drug thread on this subforum. As the information given is limited anyone considering please proceed with caution. In the US you will need your neuro to work with you I believe. I don't know anything bad about this but the secrecy means I don't know much.
Shovon, I think since you are not diagnosed you might be better served not focusing on ALS at all. If you must do so, perhaps read the research threads to see what has been discussed
