Disability

The degree of disability experienced by ME/CFS patients covers a wide range, but can be very severe.

Statistics

 * 54% of ME/CFS patients reported being unemployed
 * 25% of ME/CFS patients are housebound or bedbound at some point in their illness
 * A number of studies and patient surveys have found patients with ME/CFS to have, on average, a lower quality of life, to be more severely disabled, and to have more comorbid chronic illnesses than patients with any of the other chronic illnesses used for comparison. (Neurological Alliance, 2019 ; Hvidberg et al. 2015 ; Nacul et al. 2011 )

Medical Evidence

For the purposes of Social Security Disability evaluation, in addition to a diagnosis of ME/CFS that meets the Fukuda case definition, one or more of the following medical signs clinically documented over a period of at least 6 consecutive months is required to establish the existence of a medically determinable impairment (MDI) of CFS:
 * palpably swollen or tender lymph nodes on physical examination;
 * nonexudative pharyngitis;
 * persistent, reproducible muscle tenderness on repeated examinations, including the presence of positive tender points; or
 * any other medical signs that are consistent with medically accepted clinical practice and are consistent with the other evidence in the case record. For example, the Canadian Consensus Criteria (CCC) and International Consensus Criteria for ME (ME-ICC) explain that an acute infectious inflammatory event may precede the onset of CFS, and that other medical signs may be present, including

Laboratory Findings
 * – frequent viral infections with prolonged recovery,
 * – sinusitis,
 * – ataxia,
 * – extreme pallor, and
 * – pronounced weight change. [ Gain or loss.]

Specific laboratory findings are not well established for ME/CFS. However, certain laboratory findings may support the finding of an MDI in people with ME/CFS even in the absence of the medical evidence listed above. It is not unusual to find standard laboratory tests in the normal range for many patients with ME/CFS, and SSA advises that such tests should not be relied upon to the exclusion of all other clinical evidence in decisions regarding the presence and severity of an MDI. The following laboratory findings establish the existence of an MDI in people with ME/CFS: New laboratory and clinical evidence may emerge with continued research in ME/CFS. According to SSA, these findings may be considered, in conjunction with laboratory findings discussed above, in the assessment of an MDI. Depending on the type of assessment, ongoing mental limitations or neurocognitive manifestations documented by a mental status examination or psychological testing may be considered medical signs or laboratory findings.
 * an elevated antibody titer to Epstein-Barr virus (EBV) capsid antigen equal to or greater than 1:5,120, or early antigen equal to or greater than 1:640;
 * an abnormal magnetic resonance imaging (MRI) brain scan;
 * neurally mediated hypotension as shown by tilt table testing or another clinically accepted form of testing; or
 * any other laboratory findings that are consistent with medically accepted clinical practice and are consistent with the other evidence in the case record (for example, an abnormal exercise stress test or abnormal sleep studies, appropriately evaluated and consistent with the other evidence in the case record).
