Efficacy of Folic Acid in Children With Migraine, Hyperhomocysteinemia and MTHFR Polymorphisms
MTHFR gene variants C677T and A1298C seem to be related to an increased risk of migraine. Folates' metabolism could play a role in the pathophysiology of migraine. We supplemented 16 children with migraine, hyperhomocysteinemia, and MTHFR polymorphisms with folic acid and obtained a resolution/reduction of migraine attacks. Although the mechanism leading to these effects has been not made clear, we believe that the use of folic acid needs further investigations in migraineurs with hyperhomocysteinemia and MTHFR variants. A randomized, double-blind, placebo controlled crossover trial is needed to support these findings.
