I know Nancy Klimas and her team in Florida do a lot of Gulf War Illness research. They liken it to being a relative of ME/CFS but I seem to recall they say it does differ in some pretty key ways that suggest it’s a distinct illness. ISTR they’ve found evidence of differences in cytokine levels and other markers of immune function in their research. I would investigate her work if it’s of interest.
