Abstract - The impact of serum 25-hydroxyvitamin D level on migraine headache
Gökhan Özer

Objective: To investigate the impact of serum 25-hydroxyvitamin D levels on migraine headache in migraineurs

Patients and Methods: A total of 72 patients were included in the study. Serum vitamin D concentration and its impact on the migraine headache were assessed in migraineurs and migraine subgroups. To assess serum levels of vitamin D, 25(OH) D3 was measured by enzyme-linked immunosorbent assay (ELISA). Patients were categorized as follows based on the results of serum vitamin D measurements. Severity of migraine, average duration and frequency of attacks per month were recorded. The headache diary result (HDR) was determined as: Duration of headache × frequency of headache.

Results: Average vitamin D level was 7.4 ng/ml among patients with migraine with aura group and 8.5 ng/ml in patients with migraine without aura. Severe vitamin D deficiency was detected in 14 (66.7%) patients with migraine with aura and 9 (64.3%) patients with migraine without aura, with no statistically significant difference between the two groups. No significant correlation was found between vitamin D levels and HDR among migraineurs (r=-0.042, p=0.812) as well as in patients with migraine with aura (r=0.044, p=0.842) and in patients with migraine without aura (r=0.059, p=0.842) versus control group with respect to HDR and vitamin D levels. The severity of migraine pain was not associated with vitamin D levels. Serum vitamin D concentration was lower in male patients versus control group.

Conclusion: The impact of vitamin D on the severity and number of migraine attacks is not clear. Further studies are needed to demonstrate the association between vitamin D status and neurological diseases.
