Chronic Fatigue Disorder – Exhausting Disease.

Definition

Chronic fatigue syndrome is a condition of prolonged and severe tiredness or weariness that is not relieved by rest and is not directly caused by other conditions. To be diagnosed with chronic fatigue syndrome, the tiredness must be severe enough to decrease ability to do regular work or activities by 50%.

Causes, Incidence and Risk Factors

The exact cause of chronic fatigue syndrome (CFS) is unknown. Some researchers suspect it may be caused by a virus. However, no distinct viral cause has been identified. Recent studies have shown that the chronic fatigue syndrome may be caused by inflammation of pathways in the nervous system and that this inflammation may be some sort of immune response or autoimmune process. CFS may occur when a viral illness is complicated by an inadequate immune response. Other factors such as age, prior illness, stress, environment or genetic disposition may also play a role. CFS most commonly occurs in women ages 30 to 50.

Few known disorders

The condition at the time of CFS may be associated with diminished blood flow to certain parts of the brain. Clinicians have identified several other possible causes including the autonomic nervous system dysfunction. Chronic sleep disorders, emotional stress or trauma, endocrine system dysfunction, upper spinal cord injury and viral or bacterial infection can also be the cause for the chronic disorder.

Background of CFS

Chronic fatigue syndrome (CFS) is a disorder of unknown etiology that probably has an infectious basis. CFS is a state of chronic fatigue, which exists without other explanation for long and is accompanied by cognitive difficulties. Various unrelated infectious diseases appear to lead to a state of prolonged fatigue in some patients. If the condition is accompanied by cognitive difficulties, the disease is termed CFS. While the cause of CFS is unknown, the disease probably is an infectious disease. The viruses that may lead to a state of chronic fatigue do not cause CFS. One or more viruses have been implicated as the cause of CFS. As no direct tests aid in the diagnosis of CFS, the disease is a diagnosis of exclusion but one that meets certain clinical criteria, which are further supported by certain nonspecific tests.
