Chronic fatigue syndrome: what is it?

The myalgic encephalomyelitis, commonly known as chronic fatigue syndrome is a mysterious disease: it is not clear what the cause or what would be cured. Considered a neurological disease, it often appears so acute, causing a rapid and substantial deterioration of health.

Fatigue of myalgic encephalomyelitis / chronic fatigue syndrome (ME / CFS) is distinguished from other types of fatigue. One in five people who consult a doctor says a great life fatigue. However, the chronic fatigue syndrome is characterized not only by chronic fatigue, but by a combination of debilitating symptoms, including muscle and joint pain, weakness and malaise significantly reducing the professional and personal activities. All these symptoms occur without the physician may be linked to any disease. Sometimes, an event trigger is found: a viral infection, immunization, anesthesia, physical trauma, exposure to environmental pollutants, etc..

Contrary to what is still thought a few years ago, all ages (even children), and all ethnicities may be affected by this disease and not just people of Caucasian origin. However, women are 2 to 4 times more affected than men.

Although there are references to chronic fatigue syndrome until the 1750s, it was not until 1988 that he was formally recognized as a disease. More than 1 000 names have already described this state (some are still commonly used), including neurasthenia, postviral syndrome or syndrome yuppies (for “Young Urban Professionals”, mainly because it strikes early thirties).

Causes
Most people with chronic fatigue syndrome led a healthy and active life before being hit by the disease.

The hypothesis of a viral cause is more and more certain, because we can often identify an infection as a trigger. There is convincing evidence of an immune system dysfunction in the cells responsible for fighting the infection1. Research has shown weakness naturelles2 killer cells and biochemical dysfunction of cells responsible for absorbing and removing foreign bodies in the circulating sang3.
Evolution

The chronic fatigue syndrome evolves very variable. Its most acute usually last 2 years and can return cyclically. Symptoms tend to decrease with time. Few patients recover completely, but gradually, the majority finds much of its capacity. A small number may become disabled or suffer from depression.

Diagnosis

Often the person suffering from extreme fatigue and chronic must undergo numerous medical tests. This is due to the fact that many diseases result in significant reduction of energy. These include, for example, fibromyalgia, hypotension, chronic infectious mononucleosis, hypothyroidism and the syndrome of irritable bowel.

It should not be confused with depression. Unlike the depressed person who finds pleasure in nothing, “chronic fatigue” appreciates the joys of life, but quickly exhausted, leading to frustration and a sense of imprisonment.

According to the Canadian Consensus on diagnosis of chronic fatigue syndrome requires that symptoms of chronic fatigue, fatigue after exercise, sleep disturbances and significant pain are present. The patient must also have at least 2 neurological or cognitive symptoms, and at least one symptom type endocrine, immune and autonomic nervous system (see Symptoms section). In children, symptoms may vary greatly from one day to another, but are as important as adults. Among them, the diagnosis can be made if the characteristic symptoms last for more than 3 months

Tiredness, difficulty sleeping or joint and muscle pain is something that everyone has ever experienced. However, there is a percentage of the population is extremely tired permanently without any cause that justifies it. This is the most extreme exhaustion characteristic of Chronic Fatigue Syndrome, a disease of unknown cause that affects mainly women between 20 and 50 years.

1. What is Chronic Fatigue Syndrome (CFS)?
Symptoms. Patients have an increased temperature and the appearance of special nodes.
Chronic fatigue syndrome is a medical chart appears more or less rapidly and affects people aged between 20 and 50, mainly women. In many cases no previous symptoms, although most of the time has previously been strep.

Patients have an increased temperature and the appearance of special glands, small joint and muscle discomfort, headache, impaired memory or concentration and, above all, extreme fatigue that persists more than twenty-four hours after making an effort. This extreme tiredness, which is the hallmark of chronic fatigue syndrome, is inexplicable and not have any particular justification or apparent reason. Small is often accompanied by psychological disturbances such as insomnia, anxiety, nervousness or depression.

Most patients can make a normal life even though there are cases in which they are unable to perform their daily activities. In other patients manifested a significant exercise intolerance and weight bearing or go shopping.

2. Causes
Cause. The cause is attributed more prior infection with a virus of the herpes family.
Despite numerous studies, so far no one knows the origin that causes chronic fatigue syndrome although many factors are shuffled.

The cause is attributed more prior infection with a virus of the herpes family. Has been associated mainly with Epstein Barr virus, which causes infectious mononucleosis. There are also cases relating to a past or active infection with other markers of persistent viruses such as cytomegalovirus, herpes virus 6 and others.

Other factors that can influence are small immunological disorders, ie disorders of antibodies that mediate the body’s defense. Furthermore, it has considered the possibility that there may be little or no alterations in neuroendocrine, hypotension, central nervous system …

By determining antibodies can we know whether there has been prior infection with one of these viruses. However, there is no assurance that 100 per cent of cases the causes are these. A proportion of patients in whom there is no association with these viruses or have not previously had any kind of infection.

There is now talk of two types of chronic fatigue syndrome: the classic, caused by a viral infection, and idiopathic, which is one that has no demonstrable relationship to a virus of unknown origin.
