Controversies in neurological infectious diseases.
Greenlee, J E, Rose, J W · Seminars in neurology · 2000 · DOI
Quick Summary
This is a review article that discusses six controversial topics in infections affecting the nervous system. One of these topics is whether viruses might play a role in chronic fatigue syndrome (ME/CFS). The authors examine what scientists know and disagree about regarding these infections and their treatments.
Why It Matters
This review is historically significant because it documents that viral infection was recognized as a controversial hypothesis in ME/CFS research by major neurological authorities at the turn of the millennium. It highlights that infectious triggers for ME/CFS have been a persistent area of scientific investigation, legitimizing this research direction within neurology.
Observed Findings
- Viral infection is identified as a controversial potential contributor to chronic fatigue syndrome
- Multiple infectious agents have been investigated in relation to ME/CFS
- Uncertainty exists regarding the role of specific pathogens in neurological disease
- Both advances and new questions have emerged in understanding neurological infectious diseases
Inferred Conclusions
- The authors conclude that infectious agents may play a role in ME/CFS, though this remains controversial
- They suggest that new diagnostic and therapeutic options have created both progress and uncertainty in the field
- They infer that further investigation is needed to clarify infectious contributions to ME/CFS and other neurological conditions
Remaining Questions
- What specific infectious agents, if any, trigger ME/CFS in susceptible individuals?
- How do chronic infections interact with immune and neurological dysfunction in ME/CFS?
- What diagnostic methods can definitively establish infectious causation versus association in ME/CFS?
- Why do some individuals recover from presumed triggering infections while others develop chronic illness?
What This Study Does Not Prove
This review does not prove that viruses cause ME/CFS—it only documents that this was a debated hypothesis. It is a review of existing literature rather than original research presenting new evidence. The 2000 publication date means it does not reflect more recent findings about ME/CFS pathophysiology.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
