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 symptoms
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
 * 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
