Chronic Fatigue Diagnosis

The more you understand about any subject, the more interesting it becomes. As you read this article you'll find that the subject of Chronic Fatigue is certainly no exception.

Diagnosis of chronic fatigue and immune dysfunction syndrome (CFIDS), also known as chronic fatigue syndrome (CFS), is a time-consuming and difficult process which is generally arrived at by excluding other illnesses with similar symptoms and comparing a patient's symptoms with the 1994 International case definition. As yet, there is no indicator or diagnostic test that can clearly identify the disorder. Overlapping symptoms can occur with several conditions, such as fibromyalgia, Gulf War Illnesses and multiple chemical sensitivities. Many diseases have similar symptoms including lupus, hypothyroidism and Lyme disease and these need to be considered when making a diagnosis.


What You Can Expect
Your physician will take a medical history, asking questions about your past health (you will probably be asked to complete a written form - often done before your appointment time). It is likely that you will be asked about your past and current mental health as well. You can expect to receive a basic physical exam. Several types of routine blood tests and those that exclude alternative diagnoses are almost certain to be ordered. Other tests that are designed to identify central nervous system problems or viral syndromes may be ordered as well, depending on your symptoms. It's important to answer questions honestly and completely - and don't hesitate to ask your own questions. If you have thought of questions before your appointment, it's a good idea to write these down and bring them with you. Also, bring a list of medications and supplements that you're taking - be sure to include dosages. In addition, bring paper and pen with you to write down instructions. If cognitive problems interfere with the ability to write instructions or understand them, ask a friend or family member to accompany you.

It's really a good idea to probe a little deeper into the subject of Chronic Fatigue. What you learn may give you the confidence you need to venture into new areas.

Diagnostic Criteria / Case Definition
In 1994 an updated case definition was developed by an international working group of CFIDS experts. Although the criteria were designed to be used for research purposes, physicians utilize them as diagnostic guidelines for CFIDS. The case definition criteria calls for four of eight symptoms to be present along with fatigue that interferes with physical, mental, social and educational activities. Both the fatigue and symptoms must have occurred for [at least] a six month period. People with CFIDS may experience many more than the eight symptoms named in the case definition, so knowledgeable physicians will take this fact into consideration when making a diagnosis (after other possible reasons for symptoms have been ruled out).

Waiting for the Diagnosis
After testing has been completed and the physician has ruled out alternative diagnoses, he or she will inform you of the probable diagnosis. If you have research articles and other CFIDS factual information, you may wish to share this with your doctor while in the diagnostic process. With CFIDS, it's not uncommon for patients to be better informed than many physicians, so feel free to courteously share your knowledge. The diagnostic process may be lengthy - some people wait many months (or years) to be diagnosed. It may take an enormous amount of patience. In the meantime, talk with your doctor to work out the best treatment plan for symptom relief and to improve function.
