Here's another article on MB, but what I found most informative were the comments! Apparently there are a few folks self-dosing for Alz. with improvement.

I still am not clear whether one can take this while also taking Azilect or not, or what the dose would be, but am glad it seems to be helping some. Note the comment someone made about rigidity decreasing in the Alzheimer's loved one, maybe you'd see the same in PD?
