Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), post-viral fatigue syndrome (PVFS) and various other names, is a syndrome of unknown and possibly multiple etiology, affecting the central nervous system (CNS), immune, and many other systems and organs. Most definitions other than the 1991 UK "Oxford", require a number of features, the most common being severe mental and physical depletion, which according to the 1994 Fukuda definition is "unrelieved by rest", and is usually made worse by even trivial exertion (controver ...

At this time, there is no accepted conclusive test or series of tests of chronic fatigue syndrome. CFS is therefore largely an exclusionary diagnosis. If a doctor suspects a patient may have CFS they should begin the diagnostic process by eliminating other potential causes of the patient's symptoms. "Chronic fatigue" and similar symptoms can be caused by a wide variety of conditions which should be investigated, although treatment of the patient's symptoms can begin before a complete diagnosis is made. In a patient displaying CFS symp ...

Fibromyalgia is a debilitating chronic syndrome (constellation of signs and symptoms) characterized by diffuse pain, fatigue, and a wide range of other symptoms. It is not contagious, and recent studies suggest that people with fibromyalgia may be genetically predisposed[1]. It affects more females than males, with a ratio of 9:1 by ACR criteria [2]. Fibromyalgia is seen in 3-10% of the general population, and is mostly found between the ages 20 and 50. The nature of fibromyalgia is not well understood, and there is no cure, though it ...

The word chronic comes from Chronos, the ancient Greek god of time. Chronic - Medicine. In medicine, a chronic disease is a persistent and lasting condition. More accurately, the chronic disease has a chronic course. Chronicity is usually defined as lasting more than three months. A chronic course must be differentiated from a recurrent course, where the disease relapses repeatedly, the relapses being separated by periods of temporary remission. The chronic course ...

Fatigue is a state, following a period of mental or physical activity, characterized by a lessened capacity for work and reduced efficiency of accomplishment, usually accompanied by a feeling of weariness, sleepiness, or irritability. It may also follow when, from any cause, energy expenditure outstrips restorative processes and may be confined to a single organ. Fatigue can also be quite dangerous when performing certain duties that require constant concentration, such as driving a vehicle. When someone is sufficiently fatigue ...

Muscle weakness (or "lack of strength") is the inability to exert force with ones muscles to the degree that would be expected given the individual's general physical fitness. A test of strength is often used during a diagnosis of a muscular disorder before the etiology can be identified. The term subsumes two other more specific terms, true weakness and perceived weakness. True weakness (or "objective weakness") describes a condition where the instantaneous force exerted by the muscles is less ...

A Psychosomatic illness is an illness which exists because of a particular reason. "Psycho-" means of the mind and "-somatic" means of the body. The body and mind are together interacting. That is the meaning of the word. An illness produced by or maintained by the interaction is properly called a psychosomatic illness. In some instances a psychosomatic illness might otherwise become cured but for the interaction of mind and body. An example of this situation are the things like stomach ulcers that are more often found in high stress ...

Autoimmune diseases arise from an overactive immune response of the body against substances and tissues normally present in the body. In other words, the body attacks its own cells. Today there are more than 40 human diseases classified as either definite or probable autoimmune diseases, and they affect 5% to 7% of the population. Almost all autoimmune diseases appear without warning or apparent cause, and most patients suffer from fatigue. The causes of autoimmune diseases are still obscure: Some are thought to be either examp ...

Chronic renal failure (CRF, or "chronic kidney failure", CKF) is a slowly progressive loss of renal function over a period of months or years and defined as an abnormally low glomerular filtration rate, which is usually determined indirectly by the creatinine level in blood serum.

Bradycardia, as applied in adult medicine, is defined as a heart rate of under 60 beats per minute, though it is seldom symptomatic until the rate drops below 50 beat/min [1]. It is also less commonly known as brachycardia. Trained athletes tend to have slow resting heart rates, and resting bradycardia in athletes should not be considered abnormal if the individual has no symptoms associated with it. The term relative bradycardia is used to explain a heart rate that, while not technically below 60 beats per minute, is considered too sl ...

Alastair Lynch (born 19 June 1968) is an Australian Football League full forward from Burnie, Tasmania who had a highly-successful career, despite chronic illness and injury. He began his senior football career at Fitzroy in 1988. He was an intimidating player in defence even from the beginning with the ability to take a strong mark and lay a heavy tackle. However, he was not noted for his goalkicking at this time. He left Fitzroy after the 1993 season to join the then struggling Brisbane Bears who were coached by Premie ...

Chronic fatigue syndrome - Onset. Some cases of CFS start gradually, but the majority start suddenly, often triggered by a 'flu-like viral or similar illness. People with CFS may improve or recover completely after a few or many years, or not at all. It is not known whether any CFS sufferer has truly recovered to pre-illness levels, or whether their symptoms have merely subsided enough for them to live a more normal life. Some sufferers have a remission for months or years ...

Due to problems with the definition of CFS, estimates of its prevalence vary widely. Studies in the United States have found between 75 and 420 cases of CFS for every 100,000 adults. Far more women than men get CFS — between 60 and 85% of cases are women. Members of ethnic minorities and low income classes are slightly more likely to develop CFS. Though people of all ages can get CFS, and precise statistics are not available, the prevalence among children and adolescents appears to be lower than for adults. A ...

According to the 1994 Fukuda definition there are eight main categories of symptoms in CFS: Fatigue: People with CFS experience profound, overwhelming exhaustion, both mental and physical, which is worsened by exertion, and is not relieved (or not completely relieved) by rest. To receive a diagnosis of CFS, this fatigue state must last for six months. Pain: Pain in CFS may include muscle pain, joint pain (without joint swelling or redness, and may be transitory), headaches (particularly of a new type, severity, or durat ...

Chronic fatigue syndrome:

an illness characterized by long periods of fatigue, often accompanied by headaches, muscle pain and weakness, and elevated antibody titers to some herpes viruses. The cause or causes are unknown.

(See also: Chronic fatigue syndrome, Alternative Medicine, Body Mind and Soul)

Chronic fatigue syndrome carries a considerable stigma, and has frequently been viewed as malingering, hypochondriacal behavior, "wanting attention" or "yuppie flu". As there is no objective test for the condition at this time, many argue that it is easy to "invent" CFS-like symptoms for financial, social or emotional benefits. CFS sufferers argue in turn that the perceived "benefits" are hardly as generous as some may believe, and that most CFS pa ...
