The aetiopathogenesis of fatigue: unpredictable, complex and persistent

Area of Science:

• Complex systems biology
• Integrative medicine
• Pathophysiology research

Background:

• Chronic fatigue syndrome (CFS) presents with severe fatigue, post-exertional malaise, cognitive impairment, and pain.
• CFS symptoms overlap with other conditions, complicating diagnosis.
• Existing research shows widespread autonomic, endocrine, and inflammatory system impairments.

Purpose of the Study:

• To address the lack of consensus on CFS pathophysiology.
• To propose a new research framework for fatigue syndromes.
• To integrate multi-system findings and environmental factors.

Main Methods:

• Literature review and theoretical synthesis.
• Discussion of non-determinism, non-reductionism, and self-organization principles.
• Conceptual integration of multi-systemic and environmental influences.

Main Results:

• Current research on CFS pathophysiology has reached an impasse.
• A shift from single-system focus to an integrated, multi-system approach is needed.
• Non-determinism, non-reductionism, and self-organization offer a coherent framework.

Conclusions:

• An integrated, multi-system approach is crucial for understanding CFS.
• This framework provides promising avenues for future CFS research.
• Adopting these principles can advance aetiopathogenesis and treatment strategies for fatigue syndromes.
