Hypersensitivity
 | This article is a stub. |
Patients with ME/CFS can have a range of hypersensitives, which may mild or severe. Hypersensitives recognized in ME/CFS include sensitivity to:
- light (photophobia)
- sound (hyperacusis)
- touch
- foods intolerances
- odor sensitivities
- chemicals, including developing multiple chemical sensitivities (MCS)
Hyperalgesia, which is a greatly increased sensitivity to pain, may also occur.[1]

Canadian Consensus Criteria[edit | edit source]
Perceptual and sensory disturbances count as one of the Neurological/Cognitive manifestations used for diagnosis, the examples given are: "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."1,2
The following hypersensitivity and sensory symptoms are recognized in Appendix 4:
- hyper-responsiveness to noxious stimuli
- feeling of burning or swelling
- loss of cognitive map
International Consensus Criteria[edit | edit source]
Hypersensitivities are divided into a few main areas, as optimal diagnostic criteria:
- Neurocognitive symptoms:
- Neurosensory and perceptual: e.g. inability to focus vision, sensitivity to light, noise, vibration, odor sensitivities, taste and touch; impaired depth perception.[2]
- Immune, Gastro-intestinal and Genitourinary:

Canadian Consensus Criteria (CCC) - A set of diagnostic criteria used to diagnose ME/CFS, developed by a group of practicing ME/CFS clinicians in 2003. The CCC is often considered to be the most complex criteria, but possibly the most accurate, with the lowest number of patients meeting the criteria. Led to the development of the International Consensus Criteria (ICC) in 2011.
cognition - Thought processes, including attention, reasoning, and memory.
International Consensus Criteria (ICC) - A set of diagnostic criteria, based on the Canadian Consensus Criteria, that argued for the abandonment of the term "chronic fatigue syndrome" and encouraged the sole use of the term "myalgic encephalomyelitis".
chronic fatigue syndrome (CFS) - A fatigue-based illness. The term CFS was invented invented by the U.S. Centers for Disease Control as an replacement for myalgic encephalomyelitis (ME). Some view CFS as a neurological disease, others use the term for any unexplained long-term fatigue. Sometimes used as a the term as a synonym of myalgic encephalomyelitis, despite the different diagnostic criteria.
