A Cross-sectional Study to Assess Psychiatric Co-morbidity among Patients of Migraine and Other Headaches

Introduction: Migraine is the most common cause of vascular headache with a one-year prevalence as high as 6-14.3%. Having various pathophysiological theories, it occurs in much co-morbidity with several medical as well as psychiatric disorders like mood disorders, phobia, anxiety spectrum, etc. Migraine, especially when co-morbid with psychiatric illness stands markedly burdensome economically, diagnostically, therapeutically and prognostically. Hence, needs even further research. Aim: To study patients with migraine versus other types of headache and to study psychiatric co-morbidity among patients with migraine. Materials and Methods: This cross-sectional study was conducted on total 100 patients presenting with headache, meeting the criteria were taken up for the study and divided into two groups. Patients meeting International Headache Society (IHS) criteria for migraine were enrolled under group A and patients suffering from headache other than migraine under group B. Having subjected to detailed history and evaluation, patients were subjected to Symptom checklist-80, Hamilton’s Anxiety Rating Scale (HARS) and Montgomery Asberg Depression Rating Scale (MADRS), International Classification of Diseases (ICD)-10 criteria. The data so collected was subjected to statistical analysis and association of psychiatric morbidity with migraine patients was assessed. Results: Patients with migraine (group A) and among those too, patients having psychiatric morbidity had significantly (p<0.01) longer duration of illness (≥8 years), more frequent attacks ≥5 attacks per month and had longer duration of each attack >24 hours compared to the other groups. Patients having migraine had significantly (p<0.01) higher psychiatric morbidity, more SCL-80 symptoms (mean score 83.05); more depressive symptoms (mean MADRS score was 31.9±9.2) and more anxiety with the mean Hamilton Anxiety score was 23.3 than in patients without psychiatric morbidity. Conclusion: A thorough evaluation of psychiatric disorders in migraine is important so as to propose a non segregated model of care to direct the burden and deterioration associated with psychiatric co-morbidity in migraine.
