Dopamine and prolactin in migraine: Mechanisms and potential therapeutic targets.
Review in Journal of neuroendocrinology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Migraine is a complex neurovascular disorder characterized by activation and sensitization of the trigeminovascular system. Hyperprolactinemia is associated with headache, and improvement following prolactin-lowering therapy has been reported in observational studies. Preclinical evidence indicates that prolactin promotes neuronal excitability and sensitization within trigeminal pathways, particularly in females. Downregulation of the protective long prolactin receptor isoform further increases susceptibility to migraine-relevant triggers. Prolactin secretion is under tonic inhibition by dopamine, a key hypothalamic regulator that also modulates central pain pathways. The role of dopamine in migraine pathophysiology is complex. On one hand, prodromal symptoms such as nausea and yawning are considered dopamine-mediated. On the other hand, experimental studies show that dopamine directly inhibits nociceptive trigeminovascular activity in addition to lowering prolactin. Dopamine receptor agonists are established treatments for hyperprolactinemia and have demonstrated a positive effect on hyperprolactinemia-associated headache. A recent placebo-controlled randomized clinical trial suggests that dopamine agonist treatment can be used as a preventive migraine treatment. In conclusion, prolactin and dopamine may modulate migraine via distinct but converging neuroendocrine pathways, which could represent targets for migraine prevention.
