This 1991 editorial discusses what doctors understood about ME/CFS at that time. The author suggests that ME/CFS is likely connected to depression, mild immune system problems, or a combination of both, rather than being caused by Epstein-Barr virus alone. The article recommends that doctors use careful patient interviews, physical exams, and basic blood tests to diagnose the condition, and that supportive, hopeful care is important for treatment.
Why It Matters
This editorial is historically important for understanding how ME/CFS was conceptualized in early clinical practice and the shift away from purely viral explanations. However, it also reflects the era when psychiatric attribution was common, which influenced clinical approaches for decades and may have delayed investigation into biological mechanisms now being documented in modern ME/CFS research.
Observed Findings
EBV is no longer considered an important cause of ME/CFS
Subtle immunologic dysfunction may be present in some patients
Psychiatric disorders may coexist with or contribute to ME/CFS
Basic clinical assessment and laboratory testing are described as usually sufficient for diagnosis
Antidepressants and NSAIDs may be effective in selected patients
Inferred Conclusions
ME/CFS is likely multifactorial, involving psychiatric and/or immunologic components rather than a single viral cause
Clinicians should employ empathetic, optimistic long-term follow-up as a therapeutic approach
Routine diagnostic testing combined with careful history is recommended as the standard diagnostic pathway
Remaining Questions
What are the specific immunologic dysfunctions present in ME/CFS and how do they differ from healthy controls?
What is the temporal and causal relationship between psychiatric symptoms and ME/CFS onset and progression?
Why do some patients respond to antidepressants or NSAIDs while others do not, and what mechanisms underlie these responses?
What This Study Does Not Prove
This editorial does not establish causality between psychiatric disorders and ME/CFS through empirical data. It represents expert opinion from 1991 and does not prove that psychiatric factors are primary rather than secondary consequences of the disease. The dismissal of EBV's role was premature, as subsequent research has shown post-viral mechanisms may be relevant in some ME/CFS cases.
