I've been investigating the connection between migraine and depression—two debilitating disorders with high comorbidity. My overarching goal is to unravel their pathophysiology and pinpoint associated risk factors to pave the way for more effective therapeutic interventions. The fruits of my labor is discussed in the introductory part of the thesis and comprises four first-author publications in international peer-reviewed journals.

In the first two projects, I worked mostly on the comorbid aspects of migraine and depression. I conducted a meta-analysis on the efficacy of onabotulinumtoxinA injections as a treatment for those grappling with both migraine and depression. The findings were promising, showing not only the treatment's safety and effectiveness but also hinting at a shared pathophysiology between the two conditions. The second project delved into the structural brain anatomy, utilizing voxel-based magnetic resonance imaging measures to explore subcortical volumes in migraine and depression patients. The distinct patterns observed suggest a nuanced relationship at the subcortical level.

Expanding beyond comorbidity, my research ventured into the occupational determinants of migraine, scrutinizing the impact of job-related factors on migraine prevalence. Leveraging data from the UK Biobank, the third project identified strong associations between migraine and specific job categories, setting the stage for future interventions and policies to enhance workers' well-being. Additionally, my exploration into the role of the cerebellum and brainstem in migraine pathophysiology, using the UK Biobank data, unveiled larger gray matter volumes in multiple cerebellar regions in individuals with migraines. This sheds light on potential mechanisms underlying migraine attacks, contributing significantly to our understanding and potential treatments for these challenging disorders.
