Previous studies have demonstrated an association between migraine and major depressive disorder. However, relatively little is known about the relationship between suicidal ideation, with or without concurrent depression, and migraine.
We conducted a systematic literature review to synthesize the available research focused on investigating the association of migraine with suicidal ideation.
Relevant research papers were identified through searches of major electronic databases including PubMed, Embase (Elsevier), Web of Science (Thomson Reuters), PsycINFO (EBSCO), and Google Scholar. We performed a meta-analysis to estimate the pooled unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (95% CI) for the association between migraine and suicidal ideation extracted from each study.
A total of 148,977 participants in 6 studies were included in this analysis. Overall, findings from available studies documented elevated odds of suicidal ideation among individuals with migraines. In unadjusted models, the odds of suicidal ideation was 2.49-fold higher among individuals with migraine (OR, 2.49; 95% CI, 2.34-2.65) compared with those without migraine. In multivariate-adjusted models, the pooled adjusted OR of suicidal ideation was 1.31 (OR, 1.31; 95% CI, 1.10-1.55).
A meta-analysis of available studies suggests a modest positive association between migraine and suicidal ideation. Further studies allowing for a more comprehensive investigation of the association between migraine and the full range of suicidal behaviors are warranted. A larger and more robust evidence-base may be useful to inform the clinical screening and diagnoses of comorbid conditions in migraineurs.
