Migraine and MRI: uncovering potential associations.

Objective: This study aims to investigate the association between patients with migraine headaches and brain magnetic resonance imaging (MRI) findings.

Background: Migraine is a frequently encountered primary headache disorder with a disproportionate female predominance. Diagnosis is usually based on the patient's clinical history with neuroimaging reserved for severe or atypical presentations to exclude other pathologies. Migraine patients often experience a profound impact on their quality of life.

Methods: A retrospective study was conducted at King Abdullah University Hospital, Jordan, involving patients with a clinical diagnosis of migraine who had undergone MRI brain imaging between January 2021 to March 2023. Descriptive data were documented, with two independent neuro-radiologists interpreting MRI findings.

Results: Our study included 670 migraine patients (510 females; mean age, 40.3 years). White matter hyperintensity lesions were found in 309 patients (46.1%), significantly affecting older age groups with a mean age of 46.8 years (p > 0.001). Additionally, gender played a role, with a higher prevalence of these lesions in female migraine patients, accounting for 79.6% (p = 0.05). Multiple logistic regression analysis proved age to be an independent risk factor for the presence of white matter hyperintensity lesions (OR: 1.0688, 95% CI: 1.0546-1.0831, p > 0.001).

Conclusion: White matter hyperintensity lesions were seen in the MRI imaging of a subset of migraine patients. Patients with these lesions tend to be older and of female gender. However, the clinical significance of these findings remains unclear.
