Alexithymia profile across migraine subtypes: a cross-sectional study
Abstract
Background: Migraine is a prevalent neurological disorder, with chronic migraine (CM) and medication overuse headache (MOH) often comorbid with psychiatric conditions. Patients with CM may experience social cognitive impairments, including alexithymia, which could contribute to their condition’s severity and prognosis. This study aims to characterize alexithymia in patients with episodic migraine (EM) and CM and explore differences in alexithymia between patients with and without aura.
Methods: This cross-sectional study included adult patients with EM, CM (with or without MOH), and healthy controls (HCs), conducted at two tertiary headache centers in Italy. Participants completed the Toronto Alexithymia Scale-20 (TAS-20) to assess alexithymia levels. Demographic, clinical, and cognitive functioning data were collected. Migraine features, including frequency, aura symptoms, and medication usage, were also recorded.
Results: The cohort included 200 migraine individuals and 79 HCs. Patients with CM exhibited significantly higher alexithymia scores (56.0±13.2) compared to EM patients (47.8±12.0, p<0.001) and HCs (44.5±11.9, p<0.001). A higher proportion of CM patients (32.0%) had pathological alexithymia compared to EM patients (16.0%) and HCs (9.0%) (overall difference, p<0.001). No significant differences were found in TAS-20 scores between migraine individuals with aura (45.2±9.9) and those without aura (49.5±13.0, p=0.182).
Conclusions: Patients with CM exhibit higher…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 200 participants or records.
