Background
Psychiatric illnesses are often associated with severe forms of headache as chronic migraine (CM) with medication overuse headaches (MOH). Few data are available about obsessive–compulsive disorders (OCD) in migraineurs. This study aimed to investigate OCD traits in CM with MOH patients of both sexes and the impact on migraine treatment.
Methods
We enrolled all consecutive patients with CM and MOH treated with onabotulinumtoxin-A (OBT-A) in our Headache Center. Each subject was submitted to the Obsessive–Compulsive Inventory-Revised (OCI-R) test at the start (T0) and after four OBT-A sessions (T1). Statistical analysis compared OCI-R results at T0 and T1 according to sex with the chi-square test.
Results
We analyzed a sample of 60 subjects (40 females, 66.7%). At T0, 25% of males and 37.5% of females had a normal profile while 60% of males and 22.5% of females presented pathologic OCD traits. At T1, 30% of males and 60% of females were normal, while 40% of males and 15% of females resulted frankly pathologic. The difference in the OCI-R distribution was significant at T0 (p = 0.024) and at T1 (p = 0.047). Both males and females underwent a significant increase in normalization rates at T1 (p < 0.05).
Conclusion
We observed a significant OCD traits rate at baseline, moreover among men. Females showed a more significant improvement in OCD traits at T1. OBT-A confirmed its high efficacy on CM, with a migraine severity improvement in both genders and all the OCI-R classes. Psychological attitude in the management of migraine should be better investigated in future studies.
