Abstract
Background
Anti-CGRP monoclonal antibodies (CGRPmAbs) enlarged migraine prevention options. They work targetedly, safely, and efficiently in many patients. Inexplicably, a proportion of patients show scarce improvement.
Objective
To identify the possible role of personality traits, determined with the Personality Inventory for DSM5 (PID5), on the efficacy of CGRPmAbs on migraine.
Methods
We evaluated 3 parameters: monthly headache days (MHD), monthly painkillers intake (MPI), and MIDAS. For each parameter, patients were classified as: (A) non-responders (reduction < 3 0% vs. baseline); (B) partial responders (30–49% reduction); (C) full responders (reduction > 50%).
Results
Ninety-seven patients treated with CGRP-mAbs were included (33 galcanezumab, 13 fremanezumab, 51 erenumab). Considering attack reduction (MHD), 53 (54.6%) were full responders, 13 (13.4%) partial responders, and 31 (32%) non-responders. Considering MPI, 61 (62.9%) were full responders, 11 (11.3%) partial responders, and 24 (24.7%) non-responders. Concerning MIDAS, 53 (53%) were full responders, 17 (17.5%) partial responders, and 21 (21.6%) were non-responders. All the 97 patients were tested with the PID5. In terms of MHDs, non-responders, in comparison with responders, showed a significant excess of disinhibition, especially in relation with the anhedonia and depressivity facets. Concerning MPI, non-responders showed increased depressivity and distractibility. MIDAS non-responders had significantly higher scores in the antagonism domain and submissiveness facet.
Discussion
Non-responders seem to have different personality traits in comparison to responders, with a higher tendency toward depressed mood and difficulty to feel pleasure previously found in migraineurs vs. non-migraineurs: the more strict certain traits are, the more difficult to treat the migraine could be.
