Severe and very severe ME







Severe and very severe ME affects about 25% of people with myalgic encephalomyelitis (ME), with patients being housebound or bedbound at some point in their illness, typically needing to use a wheelchair, unable to do any kind of work or study, and often unable to do basic self-care activities unaided. Some people have died of ME, including Sophia Mirza and Merryn Crofts.

There is no generally agreed upon description of severe or very severe ME, but different clinical scales can be used to measure the degree of disability. Very little research has described the symptoms and experiences of patients with severe ME or very severe ME, much of what is known comes from patient and advocacy groups.

Severe ME symptom scales
Substantial impairment and disability in adults can be measured using the following scales:
 * Energy Index Point Score


 * Fibromyalgia Impact Questionnaire Revised (FIQR)
 * Katz Index of Independence in Activities of Daily Living
 * The Lawton Instrumental Activities of Daily Living (IADL) Scale


 * Short-Form 36 Item Health Survey not specific to ME/CFS
 * RAND-36 - available as a free version of SF-36


 * Work and Social Adjustment Scale (WSAS)

Scales developed by patient organizations

 * HFME 3 Part M.E. Ability and Severity Scale

Comparison
Some scales have a "ceiling effect" that means severe ME can not adequately be distinguished from very severe ME, or from moderate ME, including the Chalder fatigue scale.

Some patients who are severely ill may not have enough concentration to complete a questionnaire, or may be too ill to communicate, these patients may need another person to complete the rating scale instead, for example a carer or health professional. A pilot study of patients with severe CFS/ME in North East England found that even when visiting patients at home, some were unable to complete a questionnaire or to even attempt to stand.
