Diagnostic Criteria &
Differential Diagnosis


Canadian Expert Consensus Panel Clinical Case Definition for ME/CFS
published in the Journal of Chronic Fatigue Syndrome, Vol. 11 (1) 2003
http://www.cfids-cab.org/MESA/ccpc_p.html
 

  • The following links describe the diagnostic criteria and differential diagnosis of M.E. 
    • (note: differential diagnosis means illnesses to rule out)
  • You should know that there are several definitions to describe M.E. and they are continually being modified.  In addition, the definitions for CFS and CFIDS are also different than that of M.E.
  • Current discussions continue regarding a definition for research purposes and a different, less rigid definition for clinical purposes.


SPECIAL NOTE:
chronic fatigue is NOT chronic fatigue syndrome or M.E.!
and
chronic fatigue syndrome or M.E. is NOT just chronic fatigue!
 
 

A diagnosis for any medical condition must be
made by a qualified medical professional.
