These may not be directly applicable to this study, but I can't help but notice:

1. yes, Wahl's diet is alkaline (no sugars, which makes things swing over to acidic) and

2. if one has a vascular compression in the brain, which I would think would indicate something somewhere is not getting as much oxygen as it normally would...Dr. Jannetta's theory comes into play again.

Now I know they weren't feeding these worms the typical horrific Western diet, nor did these worms have peduncle/arterial compression. But the lack of oxygen, for whatever reason, seems to have about the same effect. Which is why it's so interesting to me that Jannetta's lady patient fully regained all of her function overnight after decompression. 60-80% of your neurons in the substantia nigra simply cannot regrow overnight or even in a matter of days, I don't think, assuming they are in fact dead.
