Quick Summary
This review looked at 79 studies to understand what factors might contribute to ME/CFS in children and teenagers. The researchers found that young people with ME/CFS are more likely to also experience anxiety or depression than healthy peers. Many patients reported their illness started after an infection, and some families seemed to have multiple members with ME/CFS, though the research on these patterns is still developing.
Why It Matters
Understanding what factors might predispose, trigger, or maintain ME/CFS in young people is critical for earlier identification and targeted intervention. This review consolidates evidence about psychiatric comorbidity and infection-related onset, helping clinicians recognize patterns and potentially improve outcomes in pediatric ME/CFS populations.
Observed Findings
Psychiatric comorbidity (anxiety and depression) is significantly elevated in children/adolescents with CFS compared to healthy and illness controls
Many young people with CFS report infectious illness preceding symptom onset
Family history of CFS appears more common in CFS cases, suggesting possible familial clustering
Personality traits such as conscientiousness and physical illness attributions were preliminary associations in some studies
High parental and self-expectations were suggested as potential contributing factors
Inferred Conclusions
Psychiatric factors, particularly anxiety and depression, are consistently associated with CFS in young people and warrant clinical attention
Infectious triggers appear common in pediatric CFS onset and may represent an important precipitating factor
A multifactorial model involving predisposing (genetics, personality), precipitating (infection), and perpetuating (psychological, social) factors best explains CFS in children and adolescents
Future prospective research is essential to clarify temporal relationships and causal mechanisms
Remaining Questions
Does infection cause ME/CFS through specific immunological or neurological mechanisms, or does it trigger illness in genetically/psychologically vulnerable individuals?
What This Study Does Not Prove
This review does not establish causation—for example, finding higher depression/anxiety rates does not prove these cause ME/CFS or result solely from it; bidirectional relationships are possible. The predominance of cross-sectional studies means temporal relationships cannot be confirmed, and the review identifies correlation rather than definitive causal mechanisms.
