Dopaminergic symptoms in migraine: A cross-sectional study on 1148 consecutive headache center-based patients

Background Dopaminergic symptoms may be extremely pronounced in some migraine patients during the attack, representing a major source of disability. Objectives We aimed to carefully characterize the clinical picture of migraine patients with dopaminergic symptoms in a large patients’ population as a putative migraine endophenotype, allowing more precise disease management, treatment and outcome prediction. Methods We screened 1148 consecutive tertiary care episodic and chronic migraine patients with face-to-face interviews collecting thorough data on lifestyle, socio-demographic factors, and clinical migraine features. Results We identified 374 patients with migraine with dopaminergic symptoms (32.6%). The most frequent dopaminergic symptom was yawning followed by somnolence, nausea, vomiting, fatigue, mood changes and diuresis. Migraine patients with dopaminergic symptoms had longer attack duration (OR: 1.82; 95% CI: 1.41–2.36, p
