A Molecular Neurobiological Approach to Understanding the Aetiology of Chronic Fatigue Syndrome (Myalgic Encephalomyelitis or Systemic Exertion Intolerance Disease) with Treatment Implications.
Monro, Jean A, Puri, Basant K · Molecular neurobiology · 2018 · DOI
Quick Summary
This paper argues that ME/CFS is caused by biological problems in the brain and body rather than primarily psychological factors. The authors reviewed evidence showing that ME/CFS involves issues with immune chemicals, infections, brain barrier function, and how cells use energy. They suggest that treatments targeting these biological problems—such as supplements, antivirals, and immune therapies—should be studied instead of or alongside psychological approaches.
Why It Matters
This paper challenges the prevailing psychological model of ME/CFS and advocates for biological research into disease mechanisms and treatments. For patients, it validates the concept that ME/CFS has physical, measurable causes. For researchers, it outlines specific molecular targets and potential therapeutic approaches worthy of investigation, helping redirect research funding and clinical focus toward biological interventions.
Observed Findings
Evidence of nitric oxide-peroxynitrite pathway dysregulation in ME/CFS
Documented oxidative and nitrosative stress markers
Abnormalities in blood-brain barrier and intestinal permeability
Cytokine dysregulation and potential viral involvement
Structural and chemical brain changes detected in patients
Inferred Conclusions
ME/CFS has a molecular neurobiological basis rather than being primarily psychologically determined
Multiple interconnected biological systems are disrupted in this disease
Biologically-targeted treatments should be prioritized for future research and clinical trials
Nutritional, antiviral, and immunological interventions warrant investigation as disease-modifying therapies
Remaining Questions
Which specific molecular mechanisms are primary drivers versus secondary consequences?
Which biological treatments are most effective and for which patient subgroups?
What This Study Does Not Prove
This editorial does not present new experimental data and cannot prove causation for any proposed mechanism. It is a literature review and opinion piece, so individual claims require validation through primary research studies. The paper does not establish which proposed mechanisms are most important or which biological treatments are actually effective in practice.
