Abstract
Migraine is a neurological disorder that strongly relates to psychiatric conditions like depression. Lately, the increased prevalence of depression in migraineurs has come to attention. This article compiled various literature to explore the association between migraine and depression. Genetic overlap of various gene segments was studied, and heritability patterns were explored. Shared mechanisms such as serotonergic dysfunction, methylenetetrahydrofolate reductase (MTHFR) polymorphisms, and hormonal effects were investigated, and commonalities like comorbidities, stress, and environmental factors were analyzed. Migraine with comorbid depression (MID) affects various aspects of life and its clinical impact on migraine disability, quality of life (QOL), progression, and medication overuse was investigated. We further inspected several types of research in order to provide options on various treatment modalities. Pharmacotherapy such as antidepressants and anti-Calcitonin Gene-Related Peptide (CGRP) monoclonal antibodies like fremanezumab were studied. Alternative treatment options such as onabotulinumtoxinA (OBTA) injections, cognitive behavioral therapy (CBT), and vagal nerve stimulations (VNS) were also appraised and the efficacies of each were compared.
