简要总结
The trial is primarily designed to investigate whether treatment with vitamin D may influence migraine in a placebo-controlled, blinded study. The hypothesis is that vitamin D may serve as a prophylactic treatment of migraine. The hypothesis is tested by examining the changes in the pain and symptom patterns associated with migraine by treatment with Vitamin D, by means of quantitative sensory testing, diaries and blood samples for measurement of vitamin D. Other pain biomarkers are also measured to evaluate whether the levels of these biomarkers in the blood is changed by the treatment with vitamin D. The hypothesis here is that levels of those biomarkers will change following the treatment.

结局指标
主要结局
The number of migraine attacks
时间窗: every 4 weeks
The primary endpoint is the frequency of migraine attacks. This is estimated from the subjects' listing of attacks in the form of diaries. This is assessed as the number of migraine attacks per 4 weeks (28 days).
次要结局
- Quantitative Sensory Testing(Every 4 weeks)
- Measuring levels of a biomarker. Changes in the levels of these biomarkers.(Baseline and after 6 months treatment (end of trial))
- Migraine Symptoms(every 4 weeks)
- Hypersensitivity(Baseline and every 4 weeks)
- Evaluation of pain during migraine attacks(every 4 weeks)
