I read all of comments made but to remember what

I read all of comments made but to remember what was stated fades day by day.
I am excited about the Alzheimer's trial to begin with 60 patients (?) I was wondering if there has been any "proof of principle" or preclinical data showing that LL might help or is this just a logical step made because LL is determined that it should alleviate systems of Alzheimer's or slow progression. Don't hate me because I am beautiful or stupid!
