Frequency of Primary Headache Syndromes in Patients with a Major Depressive Disorder

Purpose The primary objective of this study was to assess the overall frequency of primary headaches in subjects with a moderate to severe major depressive disorder. A further objective was to determine the frequency of primary headache sub-types in this population. Materials and methods This descriptive, cross-sectional study was conducted at the outpatients' clinic of the department of psychiatry, Pakistan Railways Teaching Hospital, an affiliate of Islamic International Medical College, Rawalpindi. The duration of the study was from December 2016 to May 2017. One hundred and ten consecutive patients with a major depressive disorder (MDD) were assessed for a primary headache, according to the diagnostic criteria of International Classification of Headache Disorders second edition (ICHD-2). MDD patients with moderate to severe depression according to the diagnostic and statistical manual of mental disorders (DSM-5) were enrolled in the study. A semi-structured proforma was designed to gather information on sociodemographic variables. The data was analyzed by utilizing Statistical Package for Social Sciences, version 22 (IBM Corp., Armonk, NY, US). Results Of the 110 MDD patients enrolled, a primary headache was present in 45 (40.90%) cases. Additionally, five of these patients had a migraine with aura (11.11%), 12 had a migraine without aura (26.66%), and 28 had a tension-type headache (62.22%). In the females, migraines with or without aura was frequent (35.29%), while a tension-type headache was more common in males (72.72%). Conclusion More than one-third of the sample had a primary headache syndrome, which shows a high comorbidity between a migraine and its variants and MDD. There is a need to undertake further studies with larger samples to elucidate this relationship.
