We are still in the very early days (yeah, after 30 some years and more) where NIH will have to admit they need to step it up.
I get worried about the suggestion of controlled nutrition as a treatment (mentioned a couple of comments up)- the last thing we need is to be told the problem can be fixed with a couple vitamins and yet another diet.
The researchers need to add the several layers that complicates things further: gene expression, blood-brain-barrier, brain abnormalities, co-morbidities (POTS), auto-antibodies, viral reactivation, NK cells, etc.
