Ohm, I'm very interested in the Alzheimer's study as my stepfather was diagnosed about 18 months ago. I know you have explained before so maybe you can point me to one of your older posts, but I don't have as good of an understanding as to how LL is expected to help with this disease as I do with cancer or HIV. Do we think we will actually be able to reverse the effects, or would we just stop the progression? Thanks in advance.
