Abstract
PURPOSE
The aim of this study was to evaluate the prevalence of comorbid bipolar disorder (BD) among migraineurs and the impact of migraine-BD comorbidity on disease characteristics.
PATIENTS AND METHODS
A total of 120 adult patients diagnosed with migraine at a single tertiary care center were included in this cross-sectional study. Data on sociodemographic and migraine-related characteristics, family history of psychiatric diseases, comorbid psychiatric diseases, and first-episode characteristics were recorded. Mood Disorders Diagnosis and Patient Registration Form (SCIP-TURK), Mood Disorder Questionnaire (MDQ), and Hypomania Checklist-32-Revised (HCL-32-R) were applied to all patients by experienced clinicians, and clinical diagnoses were confirmed using Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). Migraine Disability Assessment Scale (MIDAS) was used to evaluate the headache-related disability. Study parameters were compared between migraineurs with and without comorbid BD.
RESULTS
The diagnosis of comorbid BD was confirmed in 19.2% of migraineurs. A significantly higher percentage of patients with comorbid BD than those without comorbid BD had family history of BD (39.1% vs 6.2%, P<0.001), suicide attempt (30.4% vs 5.2%, P<0.001), and physical abuse (52.2% vs 26.8%, P=0.019). MIDAS scores were significantly higher (50.6 [43.2] vs 33.8 [42.7], P=0.0422) in migraineurs with comorbid BD than in those without comorbid BD. Multivariate logistic regression model revealed that a positive family history of type I BD (odds ratio [OR], 14.42; 95% confidence interval [CI], 2.94-70.73; P=0.001) and MIDAS scores >30 (OR, 3.69; 95% CI, 1.12-12.19; P=0.032) were associated with 14.42 times and 3.69 times increased likelihood of BD, respectively.
CONCLUSION
Our findings revealed comorbid BD in a remarkable percentage of migraineurs and a higher likelihood of having BD in case of a positive family history of type I BD and MIDAS scores >30. Comorbid BD was associated with a higher rate for a family history of BD, suicide attempt, and childhood physical abuse as well as aggravated migraine-related disability among migraineurs. Migraineurs with and without comorbid BD showed similar sociodemographic and migraine disease characteristics as well as similar high rates for comorbid anxiety and first-episode depression.
