Dopaminergic Dysregulation in Migraine: From Hypothalamic A11 Dysfunction to a Systemic Biobehavioral Phenotype.

Dopamine plays a crucial role in migraine, alongside serotonin and CGRP. It acts as a pain filter and influences premonitory and autonomic symptoms. Researchers reviewed studies from 1976 to 2026 to understand dopamine's role better. They focused on receptor signaling, hypothalamic connectivity, and genetic factors. The A11 nucleus in the hypothalamus is particularly important. It helps regulate pain thresholds related to migraines. Dopamine levels can impact how migraines develop and feel. Higher levels of dopamine may activate specific receptors that influence pain perception. This research suggests that understanding dopamine's role can lead to better migraine treatments. By targeting this neuromodulator, clinicians may improve patient outcomes. Overall, this study enhances our understanding of the biological mechanisms behind migraines. It highlights the need for further research into dopamine's effects on migraine symptoms and treatment options. Clinical relevance: This research suggests dopamine's role in migraine could lead to improved treatment strategies targeting this neuromodulator for better patient outcomes.
