I am working on a project compiling all the symptoms associated with ME/CFS. Many people I encounter say that they not only qualify for the Canadian Criteria, but also have a bunch of symptoms not on it. I know a lot of them, but I'd like it to be complete. So if you have additional symptoms that seem associated with your ME/CFS (rather than a direct result of some other defined illness that you have) -- or if you know of additional symptoms associated with ME/CFS -- would you please share them? The Canadian Criteria are below. Thanks very much for your help. Best, Lisa * Canadian Criteria for Chronic Fatigue Syndrome A patient with ME/CFS will meet the criteria for fatigue, post-exertional malaise and/or fatigue, sleep dysfunction and pain; have two or more neurological/cognitive manifestations and one or more symptoms from two of the categories of autonomic, neuroendocrine and immune manifestations; and adhere to item 7. Fatigue The patient must have a significant degree of new onset, unexplained, persistent, or recurrent physical and mental fatigue that substantially reduces activity level. Post-Exertional Malaise and/or Post-Exertional Fatigue There is an inappropriate loss of physical and mental stamina, rapid muscular and cognitive fatiguability, post exertional malaise and/or fatigue and/or pain and a tendency for other associated symptoms within the patients cluster of symptoms to worsen. There is a pathologically slow recovery period - usually 24 hours or longer. Sleep Dysfunction There is unrefreshed sleep or sleep quantity or rhythm disturbances such as reversed or chaotic diurnal sleep rhythms. Pain There is a significant degree of myalgia. Pain can be experienced in the muscles and/or joints, and is often widespread and migratory in nature. Often there are significant headaches of new type, pattern or severity. Neurological/Cognitive Manifestations Two or more of the following difficulties should be present: confusion; impairment of concentration and short-term memory consolidation; disorientation; difficulty with information processing, categorizing and word retrieval; perceptual and sensory disturbances (e.g. spatial instability and disorientation and inability to focus vision). Ataxia, muscle weakness and fasciculations are common. There may be overload phenomena: cognitive, sensory (e.g. photophobia and hypersensitivity to noise) and/or emotional overload, which may lead to crash periods and/or anxiety. At Least One Symptom from Two of the Following Categories Autonomic Manifestations: orthostatic intolerance (neurally mediated hypotension (NMH), postural orthostatic tachycardia syndrome (POTS), delayed postural hypotension); light-headedness; extreme pallor; nausea and irritable bowel syndrome; urinary frequency and bladder dysfunction; palpitations with or without cardiac arrhythmias; exertional dyspnea Neuroendocrine Manifestations: loss of thermostatic stability (subnormal body temperature and marked diurnal fluctuation, sweating episodes, recurrent feelings of feverishness and cold extremities); intolerance of extremes of heat and cold; marked weight change (anorexia or abnormal appetite); loss of adaptability and worsening of symptoms with stress. Immune Manifestations: tender lymph nodes; recurrent sore throat; recurrent flu-like symptoms; general malaise; new sensitivities to food, medications and/or chemicals. The illness persists for at least six months. It usually has a distinct onset, although it may be gradual. Preliminary diagnosis may be possible earlier. Three months is appropriate for children.
