Docosahexaeonic acid (DHA) is the final compound in the omega-3 polyunsaturated fatty acids (PUFA) synthetic pathway and the most abundant PUFA found in the brain. DHA plays an essential role in the development of the brain, and the intakes in pregnancy and early life affect growth and cognitive performance later in childhood. Recently, it has been proposed that dietary intake of DHA could be a non-pharmacological interventional strategy for the treatment of seizures in humans. However, to date, the experimental approaches to study the antiepileptic effect of DHA have been exclusively restricted to rodent models during short-to-medium periods of treatment. The purpose of the present study was to test the chronic anticonvulsivant effects of DHA supplementation in zebrafish from the pre-spawning stage to aging, taking advantage of our recently described kainate-induced seizure model using this animal. To that end, two groups of adult female zebrafish were fed with standard or 200 mg/kg DHA-enriched diets during 1 month previous to the spawning, and offspring subdivided in two categories, and subsequently fed with standard or DHA diets, generating 4 groups of animals that were aged until 20 months. Afterward, KA was intraperitoneally administered and epileptic score determined. All the DHA-enriched groups presented antiepileptic effects compared to the control group, showing that DHA presents an anticonvulsant potential. Among the studied groups, zebrafish fed with DHA from the pre-spawning stage to aging presented the best antiepileptic profile. These results show a neuroprotective benefit in zebrafish fed with DHA-enriched diet before birth and during the whole life. [-]
