inGodshands, welcome to the forum. As you may know, NASH is an acronym for nonalcoholic steatohepatitis. Basically, it is a fatty liver with inflammation that can progress to cirrhosis, not caused by alcohol. Here is a link to some very good information on NASH:

I did not find info on cryptogenic sclerosing hepatitis, but rather on crytogenic sclerosing cholangitis, which is inflammation of the bile ducts with no specific cause. Here is a link to info on that:

I do not recall anyone posting about either of these conditions, but perhaps someone out there has had some experience with them.
I hope the above links will hold the information you seek.
