Systemic Exertion Intolerance Disease

The IOM Was Asked To Examine the Evidence Base For ME/CFS
In 2014, the Department of Health and Human Services, the National Institutes of Health, the Agency for Healthcare Research and Quality, the Centers for Disease Control and Prevention, the Food and Drug Administration, and the Social Security Administration asked the Institute of Medicine (IOM) to convene an expert committee to examine the evidence base for ME/CFS. In Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Redefining an Illness, the committee proposes new diagnostic criteria that will facilitate timely diagnosis and care and enhance understanding among health care providers and the public. These criteria, based on expert analysis and the most up-to-date scientific literature, are streamlined for practical use in the clinical setting. The IOM committee also recommends that the name of the disease be changed—from ME/CFS to systemic exertion intolerance disease (SEID)—to more accurately capture the central characteristics of the illness.

The proposed name was to hone in on key aspects of ME/CFS: "Systemic" would give credence to the disease being body wide. "Exertion Intolerance" would key doctors into understanding that the patient CANNOT tolerate exertion of any kind; physical, cognitive or emotional. (Intolerance is well understood in the clinical world in that there is a disease at hand as other diseases such as gluten intolerance is a serious medical issue and gluten CANNOT be consumed.) "Disease" gave the self explanatory label of being a biologic disease.

Diagnostic Criteria
Diagnosis requires that the patient have the following three symptoms:

1. A substantial reduction or impairment in the ability to engage in pre-illness levels of occupational, educational, social, or personal activities, that persists for more than 6 months and is accompanied by fatigue, which is often profound, is of new or definite onset (not lifelong), is not the result of ongoing excessive exertion, and is not substantially alleviated by rest, and

2. Post-exertional malaise,* and 3. Unrefreshing sleep*

At least one of the two following manifestations is also required:

1.Cognitive impairment* or 2.Orthostatic intolerance


 * Frequency and severity of symptoms should be assessed. The diagnosis of ME/CFS (SEID) should be questioned if patients do not have these symptoms at least half of the time with moderate, substantial, or severe intensity.

February 10, 2015, the Institute Of Medicine (IOM) released a Clinicians Guide
The IOM proposed the name of Systemic Exertion Intolerance Disease (SEID) and Diagnostic Criteria.
