Polyunsaturated fatty acids and epilepsy

P>Omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) are dietary fatty acids that are involved in a myriad of physiologic processes in the brain. There is some evidence suggesting that PUFAs-and particularly omega-3 PUFAs-may have anticonvulsant effects, both in humans and in animals. In the present review, we assess the evidence related to the antiseizure properties of the n-3 PUFAs, discuss their possible mechanism(s) of action, and make recommendations for future clinical trials. In general, the available data from cell cultures and whole animal studies support the idea that the n-3 PUFAs have antiseizure properties. Future clinical trials involving the n-3 PUFAs should involve higher doses and longer periods of administration in order to definitively assess their possible antiseizure effects.
