There's a grant currently available for ME/CFS researchers worldwide. I asked Prusty if he applied and he said yes but that they hadn't contacted him back... We'll see in a month or so when the deadline closes if they decide to fund Prusty's work or not. They're definitely aware of Prusty's work since they watched the last Fatigatio conference.
I don't think Prusty is the only "hope." Personally, for me there's at least 3 extremely significant developments. Prusty, DecodeME, and Long Covid. One reason why I'm looking forward to seeing Prusty's work is one of his tweets where he said that he's able to diagnose ME/CFS 75% of the time. I don't think he's the type of person that would lie about it.
Then there's DecodeME. I think it's the largest study ever on ME/CFS and it's being lead by an extremely talented geneticist, Chris Ponting. With 20,000 patients it's going to yield strong results which will either elucidate the mechanisms of ME/CFS or show that it doesn't have a genetic component. There's some evidence to show that it does though.
And now Long Covid, which is what ~10% of people develop after Covid-19 that looks extremely similar to ME/CFS. The worse the pandemic gets, the harder it will be for governments to ignore Long Covid. There are constant reports about this, doctors are talking about it, and even studies that are looking into how many people with Covid-19 develop ME/CFS are already underway like the one by OMF.
