ANSWER: Chronic Fatigue Syndrome (CFS) Myalgic Encephalopathy (ME) is persistent debilitating fatigue of recent onset, with greatly reduced physical activity and some combination of muscle weakness, sore throat, mild fever, tender lymph nodes, headaches, and depression, not attributable to any other known causes; it is of controversial etiology."

Also known by various other names, CFS/ME is a syndrome (or group of syndromes) of unknown and possibly multiple etiologies, affecting the central nervous system (CNS), immune system, and many other systems and organs of the body. There is no simple diagnostic test; CFS/ME is a diagnosis of exclusion, although recent research indicates biological hallmarks of the syndrome, and a diagnostic test is predicted soon.

ANSWER: The cause of the illness is not yet known. Current theories are looking at the possibilities of neuroendocrine dysfunction, viruses, environmental toxins, genetic predisposition, or a combination of these. For a time it was thought that Epstein-Barr Virus (EBV), the cause of mononucleosis, might cause CFS but recent research has discounted this idea. The illness seems to prompt a chronic immune reaction in the body, however it is not clear that this is in response to any actual infection - this may only be a dysfunction of the immune system itself.

A recent concept proclaimed by Prof. Mark Demitrack is that CFS is a generalized condition which may have any of several causes (in the same way that the condition called high blood pressure is not caused by any one single factor). It is known that stressors, physical or emotional, seems to make CFS worse.

Some current research continues to investigate possible viral causes including HHV-6, other herpes viruses, enteroviruses, and retroviruses. Additionally, co-factors (such as genetic predisposition, stress, environment, gender, age, and prior illness) appear to play an important role in the development and course of the illness.

Many medical observers have noted that CFS seems often to be "triggered" by some stressful event, but in all likelihood the condition was latent beforehand. Some people will appear to get CFS following a viral infection, or a head injury, or surgery, excessive use of antibiotics, or some other traumatic event. Yet it's unlikely that these events on their own could be a primary cause.

ANSWER: CFS/ME occurs more often, but not exclusively, in women, possibly due to immunological factors or hormonal changes. CFS/ME is most easily diagnosed when formerly active adults become ill, but it has been reported in persons of all ages, including young children and particularly teenagers.

ANSWER: Doctors find it difficult to diagnose CFS because it has the same symptoms as many other diseases. When talking with and examining you, your doctor must first rule out diseases that look similar, such as multiple sclerosis and systemic lupus erythematosus in which symptoms can take years to develop. In follow-up visits, you and your doctor need to be alert to any new cues or symptoms that might show that the problem is something other than CFS. When other diseases are ruled out and if your illness meets other criteria as well, your doctor can diagnose you with CFS.

Diagnostic Criteria

The criteria for diagnosing CFS were officially defined by the CDC in 1988 and revised in 2001. The Oxford criteria differ slightly. The British criteria insist upon the presence of mental fatigue, although the American criteria include a requirement for several physical symptoms, reflecting the belief that CFS has an underlying immune or infectious pathology.

Centers for Disease Control's Criteria for Chronic Fatigue Syndrome Clinically evaluated, unexplained, persistent, or relapsing fatigue that is:

• Of new or definite onset
• Not a result of ongoing exertion
• Not alleviated by rest
• Results in a substantial reduction in previous levels of occupational, social, or personal activity

Four or more of the following symptoms that persist or recur during 6 or more consecutive months of illness and that do not predate the fatigue.

• Self-reported impairment of short-term memory or concentration
• Sore throat
• Tender lymph nodes
• Muscle pain
• Multi joint pain without swelling or redness
• Headaches of a new type, pattern, or severity
• Unrefreshing and/or interrupted sleep
• Post exertion malaise (a feeling of general discomfort or uneasiness) lasting more than 24 hours

Exclusion criteria:

• Active, unresolved or suspected disease that is likely to cause fatigue
• Psychotic, melancholic, or bipolar depression (but not uncomplicated major depression)
• Psychotic disorders
• Dementia
• Anorexia or bulimia nervosa
• Alcohol or other substance misuse
• Severe obesity

Oxford (British) Criteria for Chronic Fatigue Syndrome Severe disabling fatigue of at least a 6-month duration that:

• Affects both physical and mental functioning
• Is present for more than 50% of the time
• Other symptoms, particularly myalgia and sleep and mood disturbances, may be present

Exclusion criteria:

• Active, unresolved, or suspected disease that is likely to cause fatigue
• Psychotic, melancholic, or bipolar depression (but not uncomplicated major depression)
• Psychotic disorders
• Dementia
• Anorexia or bulimia nervosa

ANSWER: Yes, too much stress can cause additional problems for people with FM/CFS/ME. It is often listed as a factor in causing flares. Most specialists recommend minimizing stress.

If you have ongoing problems with depression or anxiety, consider seeking help for them from your family doctor or a psychiatrist. Anxiety and depression may arise as symptoms of Fibromyalgia and in turn cause insomnia, leading to worsening of the underlying problem. Relaxation techniques or a chronic pain program can also help lower your stress level.

ANSWER: To find local support groups CLICK HERE. The groups in this section meet off the computer, usually in an area near your home or workplace. They discuss the challenges of living with FM and CFS/ME. They offer an upbeat atmosphere, focusing on social support, rather than therapy.

Many groups have guest speakers from the medical community who offer news on latest research, and medications. The major objective of most support groups is to provide a warm and caring environment where the illness is not questioned and where patients are accepted. Knowing that others share this journey offers comfort and reassurance.

To find a virtual or online support groups CLICK HERE. The following groups meet online only. They offer help for people unable to leave home for an actual support group meeting. Many of these groups offer monthly newsletters, research information, and forums for people with FM/CFS/ME. Groups can vary in size. Many groups have a family type atmosphere providing a warm and caring environment where the illness is not questioned and where patients are accepted. Knowing that others share this journey offers comfort and reassurance to many people with FM/CFS/ME.

ANSWER: To date, there is no published evidence that CFS/ME is contagious or transmissible from person to person. Contagious diseases tend to appear in clusters, but the overwhelming majority of CFS/ME cases appear sporadically. Furthermore, large studies conducted by the Center for Disease Control (CDC) have found no increased risk for CFS among the other members of households that have a person with CFS/ME.

ANSWER: People with CFS/ME may improve after a few months, or after many years, or never at all. They may reach a plateau at some constant level of health, or may progressively decline. Often, the symptoms change over time, or cycle irregularly. Relapses are common, especially after stressful life events or additional illness. Exertion can cause not merely a relapse, but a worsening of overall health. Undiagnosed cases of CFS/ME often worsen as the sufferer attempts to return to a 'normal' level of activity, only to make their condition worse through exertion.

Of those CFS/ME patients moderately to severely affected, many may expect to remain so for an indeterminate period, even for the duration of their life. It is not known whether any patients truly "recover" entirely from the illness, or merely recuperate enough to regain previous levels of activity.

CFS/ME can prove to be fatal, as in the case in the UK of Sophia Mirza, where the coroner recorded a verdict of "Acute anuric renal failure due to dehydration arising as a result of CFS/ME". The pathologist said,

"ME describes inflammation of the spinal cord and muscles. My work supports the inflammation theory. There was inflammation in the basal root ganglia."

It should be noted that inflammation of the 'muscles' is erroneous, as opposed to the central nervous system inflammation, as this has never been a criteria for a ME diagnosis. CFS/ME has been linked to heart damage and cardiac arrest among other causes of death; research has not yet progressed to determine whether this is in fact the case, and some patients die from co-morbid diseases. To date there is one study on CFS/ME life expectancy.

ANSWER: According to the 1994 International Case Definition the symptoms include:

• fatigue lasting for six months or longer that significantly affects lifestyle
• in addition, four or more of the following symptoms must be present [along with the debilitating fatigue]
• Postexertional malaise (lasting more than 24 hours)
• Sleep difficulties / unrefreshing sleep
• Impaired memory or concentration
• Muscle pain
• Multi-joint pain
• Headaches of new type, pattern, or severity
• Sore throat
• Tender lymph nodes in the armpit and neck

ANSWER: There is no cure for CFS/ME at this time. In fact, there is no treatment for CFS/ME, only treatments for the symptoms of CFS/ME, such as headaches, sore throats or sleep problems. Some patients partially recover, a few may fully recover, while others may find their symptoms get worse. Others experience periodic Relapses. Since little is known about the cause and progression of CFS/ME, the course of your individual illness cannot be predicted. It is important to realize that people with CFS/ME can be helped with appropriate treatment.

ANSWER: There is a great deal of research going on, regarding the possible cause of CFS, many of its symptom mechanisms, possible biological markers, treatments, and epidemiology.

• Dr. Mark Demitrack (Univ. of Michigan) and Dr. Stephen Straus (NIH) and others are studying the dysfunction of the hypothalamic-pituitary-adrenal axis as being a possible major explanation for CFS.
• Prof. Robert Suhadolnik (Temple Univ., Philadelphia) is exploring a possible bio-marker for CFS found in patients' blood.
• Dr's. Hugh Dunstan and Timothy Roberts (Univ. Newcastle, Australia) are researching a possible biological marker found in urine.
• Dr. Peter Rowe (Johns Hopkins Univ.) is studying the possible link between CFS and neurally mediated hypotension.
• Dr. Anthony Komaroff (Harvard Univ.) and Dr. Dharam Ablashi (Georgetown Univ.) are researching the possible roles of human herpes virus six and epstein-barr virus.
• Dr's. Andrew Lloyd, Ian Hickie, Denis Wakefield and Andrew Wilson (Sydney, Australia) are making broad investigations into many aspect of CFS.
• Dr. W. John Martin (Univ. So. Cal.) is studying the "Stealth" virus. Dr. Michael Holmes (Univ. Otago) is researching another mysterious, virus-like particle.
• Dr's. Nancy Klimas, Roberto Patarca (of Univ. Miami) and Jay Levy (UCSF) are investigating immunological abnormalities.
• Dr's. Paul Cheney, Charles Lapp and Jay Goldstein are studying various treatments.
• Dr's. Simon Wessely, Michael Sharpe and other British psychiatrists are exploring the value of cognitive behavior therapy for CFS.
• The Center for Disease Control team led by Dr's. Keiji Fukuda and William Reeves are undertaking prevalence studies.

These are just a few of the more prominent studies now on-going.

ANSWER: Several studies suggest that there may be a genetic component to CFS/ME. This is not surprising since CFS/ME seems to involve immune dysfunction to some degree, and immune-related illnesses often have a genetic component. The evidence on this point is not clear. And the fact that there seem to be cluster outbreaks of this illness seems to argue against genetics as being the sole factor.

ANSWER: If anything, in many cases the illness seems to be lessened for the mother during pregnancy, and no problems have been noticed with the children. Another aspect to consider is that the responsibilities of parenthood are many and are stressful, and this should be considered when planning a family.

ANSWER: If your work is, or will likely be, affected by your illness, educate your boss about your condition. Do this soon. You may need their support later when more problems may arise, and it will be easier to educate them while you are still relatively productive and "credible".

Understand that you might have to make some severe changes: a change of job, or perhaps an involuntary loss of your job and a shift to disability benefits.

Beware of the trap of losing important disability benefits if you switch to part time work. Many CFS/ME patients whose health was spiraling downwards had switched to part-time work to preserve their place with their employer. Later, when their health deteriorated even more and they needed to seek disability benefits, they found out too late that those benefits for a part-time employee did not include a livable income, whereas if they had gone straight from full-time to disability, the disability payments were much more livable. Be careful.

ANSWER: The idea of Awareness Day began in 1992. The date of May 12th date was chosen to honor the birthday of Florence Nightingale, the English army nurse who was a pioneer of the Red Cross Movement. Nightingale was virtually bedridden with a painful and fatiguing illness resembling FM/CFS/ME, yet went on to inspiring accomplishments, including the founding of the first School of Nursing.

Now Awareness Day activities take place worldwide in an effort to increase awareness of FM/CFS/ME and allow patients and organizations to educate the general public, healthcare professionals and government officials. One of the most difficult aspects of having FM/CFS/ME is that most of the symptoms are invisible, which makes it hard for others to understand what living with this debilitating illness is really like. That's one of the reasons that Awareness Day is so important.
