In the present study it has been shown for the first time that maternal methyl-enriched diet (choline, betaine, folic acid, vitamin B12, L-methionine, zinc) during perinatal period reduces the expression of genetic absence epilepsy and comorbid depression in adult offspring of WAG/Rij rats. This beneficial effect was more pronounced in males compared with females. It is assumed that epigenetic modifications induced by maternal methyl-enriched diet in the offspring at the early stages of ontogenesis might be a possible mechanism underlying the correction of genetically-based pathologic phenotype in WAG/Rij rats. Results suggest that methyl-enriched diet during perinatal period can be potentially used for mitigation or prevention epileptogenesis and depression-like comorbid disorders in people genetically predisposed to absence epilepsy.
