Psychopathological variables in chronic migraine patients with different therapeutic approach: psychological profile differences and impact on therapeutic efficacy in real life.

[BACKGROUND] Migraine is a debilitating neurological condition linked to various psychological comorbidities. The aims of our study are: 1) to evaluate potential psychopathological differences between patients in treatment with anti-CGRP monoclonal antibodies (SPECIFIC group) and those with onabotulinumtoxin-A/oral pharmacotherapy (Group NON-SPECIFIC), 2) to compare treatment efficacy over time between groups, and examined whether psychopathological comorbidities can influence it.

[METHODS] This is a post-hoc ambispective study: a retrospective analysis of patient-level real-life data prospectively collected for clinical evaluation. We enrolled 102 patients with chronic migraine (CM), 64 in treatment with erenumab or galcanezumab, and 38 with botulinum toxin or oral pharmacotherapies. Psychopathological variables are assessed at baseline, whereas clinical factors over time.

[RESULTS] The NON-SPECIFIC group showed more pronounced emotion regulation difficulties (DERS, p = 0.001), alexithymia (TAS-20, p = 0.012), and impulsiveness (BIS-11, p = 0.002) with respect to the SPECIFIC group. Moreover, treatment efficacy overtime was more pronounced in the group with anti-CGRP treatment with a reduction of migraine frequency overtime, pain intensity, and improved quality of life up to six months post-treatment. Psychopathological comorbidity did not influence treatment efficacy.

[CONCLUSIONS] Our study highlighted more pronounced psychopathological comorbidities in patients in treatment with NON-SPECIFIC therapies in terms of impulsivity, alexithymia, and emotion regulation. Moreover, treatment efficacy overtime was more pronounced and stable over time in the SPECIFIC group, and psychopathological comorbidity did not influence it.
