Chronic fatigue syndrome: a systematic review.

Area of Science:

• Medical Research
• Systematic Review
• Chronic Fatigue Syndrome (CFS)

Background:

• Chronic Fatigue Syndrome (CFS) is a complex condition with significant clinical and functional impacts.
• Defined by the CDC in 1988 and revised in 1994, CFS prevalence ranges from 0.2% to 0.7% in the general population.
• Despite extensive research into various potential factors, the underlying pathophysiology of CFS remains unknown.

Purpose of the Study:

• To conduct a systematic review of the existing literature on Chronic Fatigue Syndrome (CFS).
• To synthesize current knowledge regarding the diagnosis, classification, epidemiology, etiology, and treatment of CFS.
• To identify gaps in understanding and inform future research directions for CFS.

Main Methods:

• Systematic literature search of the Medline database using comprehensive keywords related to CFS.
• Inclusion of articles covering diagnosis, classification, epidemiology, etiology, pathophysiology, and various therapeutic approaches.
• Examination of reference lists from identified articles to ensure a thorough review.

Main Results:

• The prevalence of Chronic Fatigue Syndrome (CFS) is estimated between 0.2% and 0.7% globally.
• Multiple research areas, including infection, immunology, and neuroendocrinology, have been explored without identifying the cause of CFS.
• Current definitions of CFS, established in 1988 and 1994, highlight diagnostic criteria but not underlying mechanisms.

Conclusions:

• Chronic Fatigue Syndrome (CFS) necessitates a biopsychosocial model due to its wide-ranging clinical and functional effects.
• Progressive muscular rehabilitation is a key component of CFS management.
• Integrated behavioral and cognitive treatments are essential for effective CFS therapy.
