There may be other examples in the following text (and earlier texts of course), but here are some examples from
Gulf War and Health: Treatment for Chronic Multisymptom Illness (2013)

(Bold added - not in original)
"Because many people who have CMI also have other
unexplained conditions with shared symptoms (such as CFS, fibromyalgia, and IBS) and may have comorbid conditions (such as depression and anxiety), treatments recommended in guidelines or supported by evidence as summarized in systematic reviews for these related and comorbid conditions also were reviewed to identify any treatments potentially beneficial in people who have CMI." (p.3)
"The committee conducted a de novo systematic assessment of the evidence on treatments for symptoms associated with CMI. The committee also identified evidence-based guidelines and systematic reviews on treatments for
related and comorbid conditions (fibromyalgia, chronic pain,
CFS, somatic symptom disorders, sleep disorders, IBS, functional dyspepsia, depression, anxiety, posttraumatic stress disorder, traumatic brain injury, substance-use and addictive disorders, and self-harm) to determine whether any treatments found to be effective for one of these conditions may be beneficial for CMI." (p.4)
"Many people who have CMI also have other
unexplained conditions with shared symptoms (such as chronic fatigue syndrome, fibromyalgia, and irritable bowel syndrome) and may have comorbid conditions (such as depression and anxiety)." (p.29)
"Twelve commonly comorbid conditions or
conditions with shared symptoms were identified: fibromyalgia, chronic pain,
CFS, somatic symptom disorders, sleep disorders, functional gastrointestinal disorders, depression, anxiety, posttraumatic stress disorder, traumatic brain injury, substance use and addictive disorders, and self-harm." (p.32)
"Many of the symptoms of CFS and CFS-like illness (meeting some but not all of the criteria for CFS)
are similar to those experienced by people who have CMI. Both CMI and CFS include a variety of symptoms—fatigue, cognitive symptoms, and pain." (p.99)
"Table 5-3 shows that several treatments are considered effective in managing more than one of the
related and comorbid
conditions. There is substantial evidence in guidelines and from systematic reviews that tricyclic medications, SSRIs, and SNRIs may be used effectively in the management of patients who have conditions related to CMI. For example, SSRIs or SNRIs are recommended as therapy for seven of the conditions: fibromyalgia, somatic-symptom disorders, IBS, anxiety, depression (including depression resulting from chronic pain or CFS), PTSD, and self-harm." (p.119; Table 5.3 "Summary of Treatments Recommended in Guidelines or
Found to Be Effective in Systematic Reviews for
Conditions Comorbid with and
Related to Chronic Multisymptom Illness" - lists CFS under "condition", p.120)
P.S. Taken from an earlier post, there's also current VA info which classifies CFS as a type of chronic multisymptom illness:
http://www.publichealth.va.gov/exposures/gulfwar/medically-unexplained-illness.asp
"Gulf War Veterans' Medically Unexplained Illnesses" (Reviewed/Updated Date: March 11, 2013)
"A prominent condition affecting Gulf War Veterans is a cluster of medically unexplained chronic symptoms that can include..."
"VA refers to
these illnesses as 'chronic multisymptom illness' and
'undiagnosed illnesses.' We prefer not to use the term "Gulf War Syndrome" when referring to medically unexplained symptoms reported by Gulf War Veterans. Why? Because
symptoms vary widely."
"VA presumes certain chronic, unexplained symptoms existing for 6 months or more are related to Gulf War service without regard to cause."
"These
illnesses include...
Chronic Fatigue Syndrome, a condition of long-term and severe fatigue that is not relieved by rest and is not directly caused by other conditions."
I found another VA doc similar to the info above and will post it here (when I find it again) so this info will all be together.
