This study compared three similar long-term illnesses that cause fatigue and muscle problems: Post-polio syndrome (PPS), ME, and CFS. Researchers used questionnaires and computer analysis to identify which symptoms best distinguish these conditions from each other. They found that people with ME/CFS tend to have more severe overall functional impairment than those with PPS, and that three specific areas—brain fog, post-exertional malaise (getting worse after activity), and hormone-related symptoms—are most helpful in telling these illnesses apart.
