Risk factors of white matter hyperintensities in migraine patients

BACKGROUND: Migraine frequently is associated with White Matter Hyperintensities (WMHs). We aimed to assess the frequency of WMHs in migraine and to assess their risk factors. METHODS: This is cross-sectional study included 60 migraine patients of both genders, aged between 18 and 55 years. Patients...

Sumario:BACKGROUND: Migraine frequently is associated with White Matter Hyperintensities (WMHs). We aimed to assess the frequency of WMHs in migraine and to assess their risk factors. METHODS: This is cross-sectional study included 60 migraine patients of both genders, aged between 18 and 55 years. Patients with vascular risk factors were excluded. We also included a matched healthy control group with no migraine. Demographic, clinical data, and serum level of homocysteine were recorded. All subjects underwent brain MRI (3 Tesla). RESULTS: The mean age was 38.65 years and most of our cohort were female (83.3). A total of 24 migraine patients (40%) had WMHs versus (10%) in the control group, (P < 0.013). Patients with WMHs were significantly older (43.50 + 8.71 versus. 35.92+ 8.55 years, P < 0.001), have a longer disease duration (14.54+ 7.76versus 8.58+ 6.89 years, P < 0.002), higher monthly migraine attacks (9.27+ 4. 31 versus 7.78 + 2.41 P < 0.020) and high serum homocysteine level (11.05+ 5.63 versus 6.36 + 6.27, P < 0.006) compared to those without WMHs. WMHs were more frequent in chronic migraine compared to episodic migraine (75% versus 34.6%; P < 0.030) and migraine with aura compared to those without aura (38.3% versus 29,2; P < 0.001). WMHs were mostly situated in the frontal lobes (83.4%), both hemispheres (70.8%), and mainly subcortically (83.3%). CONCLUSION: Older age, longer disease duration, frequent attacks, and high serum homocysteine level are main the risk factors for WMHs in this cohort. The severity or duration of migraine attacks did not increase the frequency of WMHs. The number of WMHs was significantly higher in chronic compared to episodic migraineurs.
