Headaches of a new type, pattern, or severity occur commonly in ME/CFS.
- Katrina Berne reports a prevalence of 75-95% for headache, and 50% for daily headache.
- 87.8% - 92.0% of the 2073 patients in a Belgian study of 2001 reported headaches.
- In the Canadian Consensus Criteria, pain is a required criteria for diagnosis. It requires that "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."
- In the Fukuda criteria, the symptom of headaches of a new type, pattern, or severity can be used to help form a diagnosis.
- In the Holmes criteria, generalized headaches (of a type, severity, or pattern that is different from headaches the patient may have had in the premorbid state) are an optional criteria for diagnosis, under the section Minor Symptom Criteria.
