Chronic Fatigue Syndrome

CFS chart with Diagnostic Check, Common Symptoms & Risk Factors.
This chart illustrates Chronic Fatigue Syndrome (CFS/ME) and provides a comprehensive overview of the condition by organising key information into three distinct sections: Diagnostic Check, Common Symptoms, and Risk Factors. In the Diagnostic Check segment, it highlights the core criteria for diagnosis, including persistent fatigue lasting more than six months, post-exertional malaise (PEM), unrefreshing sleep, cognitive impairment, and orthostatic intolerance — features commonly required for clinical evaluation.
