This study looked at how fatigue and chronic fatigue syndrome (CFS) occur together with migraine headaches. Researchers tested 60 migraine patients and found that people with chronic migraine (constant migraines) experienced much more severe fatigue than those with episodic migraine (occasional migraines), and about 23% of chronic migraine patients met the diagnostic criteria for CFS. The study also found that fatigue was linked to depression, anxiety, and poor sleep quality.
This study provides needed quantitative data on the overlap between migraine and fatigue-related conditions, showing that chronic migraine patients carry substantial CFS burden. Understanding these intersecting conditions helps clinicians recognize and address fatigue as a core comorbidity in migraine management, which is particularly relevant since ME/CFS and migraine share overlapping pathophysiology and symptom profiles.
This cross-sectional design cannot establish causation—whether migraine causes fatigue, fatigue causes migraine, or a third factor drives both. The study does not follow patients over time to determine whether fatigue precedes or follows migraine onset. The results are from a single tertiary referral center in India and may not generalize to other populations.
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 →
