Chronic Fatigue Syndrome


What is Chronic Fatigue Syndrome?

Chronic fatigue syndrome, or CFS, is a complex illness characterized by profound fatigue that is not improved by bed rest and that may be worsened by physical or mental activity. People with CFS often function at a much lower level of activity than they did before onset of the illness. CFS can also affect memory, cause weakness and muscle pain, and insomnia.


What causes Chronic Fatigue Syndrome?

The cause or causes of CFS have not been identified. Many different infectious agents, physiologic and psychological causes have been considered. Research centers on the roles the immune, endocrine, and nervous systems may play and how these factors interact. Genetic and environmental factors may also play a role in developing or prolonging the illness.


Who is at risk?

CFS affects men and women of all ages and races. It occurs in women at two to four times the rate as in men. CFS is most common in people in their 40s and 50s, but children can develop the illness, especially during the teen years.


How is Chronic Fatigue Syndrom diagnosed?

There are no specific diagnostic tests for CFS. Your health care provider will need to rule out other known and often treatable conditions before a diagnosis of CFS is made.

In order to receive a diagnosis of CFS, you must meet the following criteria:

  1. Have severe chronic fatigue of six months or longer duration with other know medical conditions excluded by clinical diagnosis.
  2. Also have four or more of the following symptoms: substantial impairment in short-term memory or concentration; sore throat; tender lymph nodes; muscle pain; multi-joint pain without swelling or redness; headaches of anew type, pattern or severity; unrefreshing sleep; and post-exertional malaise lasting more than 24 hours.


How is Chronic Fatigue Syndrome treated?

Since there is no known cure for CFS, treatment is aimed at relieving your symptoms and improving daily function. A combination of drug and non-drug therapies is usually recommended. While some patients with CFS may see improvement over time, full recovery may be rare. Many patients experience skepticism and disbelief from others about their illness. Treating patients with respect and validating their illness may be the single most important therapy that the health care provider can offer.

Disability and Chronic Fatigue Syndrome

When CFS produces symptoms that are severe enough to prevent the patient from working, the patient may be eligible for disability benefits under Social Security. There are specific medical and disability criteria that must be met to become eligible for these benefits.

The analysis of whether the criteria are met is made for Social Security by the Disability Determination System, which is part of the Department of Children and Families.
