Introduction. Flavonoids are a large group of natural compounds that have been considered to be beneficial in ameliorating some age-dependent disorders. However, a potential use of these compounds in epilepsy treatment has not been systematically reviewed. Aim. This review describes the pharmacological activity of some polyphenols (flavonoids) in different animal models of seizures e.g. pentylenetetrazole-induced seizures, kainate-induced seizures and pentylenetetrazole kindling in rats. Method and Discussion. A literature review was conducted using PubMed from 1963 to October 2013 relating effects of flavonoids on experimentally-induced seizures in rodents. Articles chosen for references were queried with the following prompts: “flavonoids and epilepsy”, “flavonoids and seizures”, “plant polyphenols and epilepsy”, and “plant polyphenols and seizures”. Out of 84 reports 32 pharmacological studies with chemically well-defined flavonoids and using widely accepted animal models of seizures have been taken into account in this review. No clinical data on the antiepileptic effect of flavonoids have been reported so far. Conclusion. The reviewed data suggest the possible benefits of some chemically well-defined polyphenolic compounds of plant origin in antiepileptic treatment. Among flavonoids, resveratrol, baicalein, quercetin and rutin showed significant antiseizure activity. The ability of flavonoids to prevent brain excitability and to protect the brain against oxidative stress-induced damage suggests a potential use of some flavonoids at least as adjunctive therapy for the treatment of epilepsy.
