چکیده

Chronification of migraine headache is one of the major issues to resolve urgently. The prevalence of chronic migraine is close to 2%, and the chronification occurs in approximately 2.5% of episodic cases annually.The pathophysiology of transformation from episodic to chronic migraine is still unclear. It is considered that there are several risk factors for migraine chronification; 1) non-modifiable: age, low education/socioeconomic status, and head injury, 2) modifiable: attack frequency, obesity, medication overuse, stressful life events, caffeine overuse, snoring, and other pain syndrome, 3) currently putative: allodynia, proinflammatory states, prothrombotic states, and specific genes.There were a few clinical reports concerning to the migraine transformation from abroad, but few data from Japan. The prevalence of chronic daily headache in our headache clinic in Japan was 20-30%. The medication overuse headache was the most prevalent form in the highest attack frequency (>15 days/month) grope. Discontinuation of overused medication and administration of prophylactic medication were effective, and 40% of followed cases kept out of MOH at two years later.

Our study searched for evidence that genetic factors are involved in the chronification process. METHODS We initially selected 144 single-nucleotide polymorphisms (SNPs) from 48 candidate genes, which we tested for association in two stages: The first stage encompa...
