Nik, I'm skeptical of anything that claims to cure many disorders, especially those as different as Alzheimer's and autism. Why would we think that disorders with different causes would be cured by one product? And indeed, as you noticed, wouldn't there be funding for something that "costs too much to develop" if it would really help that many people? Looks like snake oil to me.
I like this link on distinguishing science from pseudoscience.

How's your DD, Nik?
