Antiepileptic drugs, hyperhomocysteinemia and B-vitamins supplementation in patients with epilepsy

Folic acid alone or folic acid combined with other B-vitamins have all been shown to reduce tHcy concentration in patients on chronic treatment with antiepileptic drugs, however, which is the most appropriate supplementation scheme of folic acid and/or B-vitamins in patients with epilepsy still remains matter of debate. We review the latest findings on the role of supra-physiological tHcy concentrations as vascular risk factor in patients with epilepsy and discuss the possible role played by folate and other B-vitamins supplementation in epileptic patient with hyper-tHcy.
