Key clinical point: Patients with episodic migraine without aura (EMoA) presented a higher delayed discounting rate, which was positively associated with the migraine history.
Major finding : Patients with EMoA vs control individuals showed a significantly higher subjective discount rate (F = 4.74; P = .032), which was positively correlated with migraine history (r = 0.742; P < .001). The resting-state functional connectivity between the left ventral striatum and middle occipital gyrus was significantly associated with migraine history (r′ = 0.294; P = .036) and subjective discount rate (r′ = 0.380; P = .006).
Study details: This study included 51 patients with EMoA and 45 control individuals who underwent task-based and multi-model magnetic resonance imaging.
Disclosures: This study was supported by the National Natural Science Foundation of China, Foundation for the Cultivation of Doctoral Research Talents, and the 2021 Youth Foundation Training Program of the First Affiliated Hospital of Anhui Medical University.
