But if ME/CFS is strictly defined as a set of criteria and a certain level of impairment, on paper they did not have ME/CFS during the good patches. But they very well might have had whatever causes ME/CFS all along.
I am not so sure. Do the criteria require symptoms every day - or definitely in the last 27 days or whatever? It takes 3-6 months to qualify for diagnosis. Maybe you can have a week off now and again? And if PEM is the cardinal feature and that is worsening presumably there are terms less worse when you might not get over the bar for 'significantly impaired' or whatever.
