Severe and very severe ME



Severe and very severe ME affects about 25% of people with myalgic encephalo&shy;myelitis (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.

What is Severe ME?
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.

A study of 19 bedbound patients with severe ME and orthostatic intolerance by van Campen et al (2020) found an average 27% decrease in blood flow to the brain during a 20 degree tilt table test that lasted just 15 minutes. Some patients could not tolerate the orthostatic symptoms for 15 mins and had to finish the test early. The patients average 35 years of age and had been ill on average 14 years. All the severely ill patients had abnormal drops in blood flow to the brain.

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 which is 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.

Very severe ME patient's experience video
People with very severe ME are totally bedbound and unable to stand at all. Some people with very severe ME have improved over time, or after surgery from cervical spinal stenosis.
