Back to the OP, Alzheimer's was also mentioned as having a similar cause and I think you know my interest in that. While I have only scanned it so far, Doxycycline is mentioned as an antibiotic which passes the blood/brain barrier and is available without prescription in Australia. YEA!!!! I've got some reading to do.
This is the problem, nobody has any interest in proving a 50c pill can cure anything.
