    Watanabe et al. have received funding to conduct a 120 participants PET brain imaging study.

    The primary outcome:
    Secondary outcomes:

    This group has previously published a ME/CFS neuroinflammation paper: https://www.ncbi.nlm.nih.gov/pubmed/24665088

    I was wondering if we were ever going to see a follow-up on this one! Awesome.

    If these brain scans cost $5000 (the figure given by Elzakker for his own study) then this is $600000 for scans alone. That's why we need government funding.

    However, crowdfunding by patients can help researchers make pilot studies that then enable big government funded studies like this one.

    This has me slightly mystified, but looks like a large-scale replicatioin of the brain neuroinflammation study that caused such a stir back in 2014: First Direct Evidence of Neuroinflammation – ‘Encephalitis’ – in ME/CFS

    120 is an enormous sample size for a PET study - a good thing but also makes it expensive. So this study could be huge for linking mecfs to neuroinflammation (activation of the brain's immune system).

    The surprise, for me, is that the 2014 paper study said a replication was under way using a better marker of inflammation but we'd not heard anything since. And the stated purpose of this study isn't a replication, but to validate secondary end-points.

    "End-points" also suggests some kind of clinical trial, but there's no methodology. So this is intriguing and potentially very exciting, but we are still largely in the dark.
