Altered Intra‐Network Functional Connectivity Predicts the 6‐Month Prognosis in Patients With Medication Overuse Headache: A Case‐Control Study

The present study provides evidence of the association between alterations of intra-network functional connectivity in intrinsic resting-state networks and six-month prognoses in patients with medication overuse headache. Our results imply potential neuroimaging biomarkers associated with the prognosis of medication overuse headache.
