This is crackpot stuff - there's no scientific evidence of any of this, it's pure grifting. The individual cited above has a phd in educational psychology and runs a pseudoscience "institute"

That's quite unfortunate. The victims and relatives of the victims of this disease are looking for any sliver of hope to ease the horrible path it takes so people like this who give false hope are truly degenerate, despicable beings. Like the people who took advantage of Farrah Fawcett's condition.
