Effects of Omega-3 Fatty Acids on Alzheimer's Disease
Omega-3 Fatty Acids in Brain and Neurological Health
There are few randomized clinical trials that studied the effects of omega-3 polyunsaturated fatty acids (ω3 PUFA) on Alzheimer's Disease (AD). Some of these studies showed that patients with mild cognitive impairment have benefits in the treatment, but none of them showed significant improvement in cognitive function in patients with advanced or moderate AD. All these randomized clinical trials had relatively short duration of supplementation, therefore, one of the Supplementation's effects of

Animal studies offer better long-term controlled research possibilities, compared to clinical studies. Methods: Therefore, a systematic literature review was conducted that focused on the effects of the relevance of long--term ω3 PUFA supplementation on cognitive impairment and neuronal loss in AD animal models. Results: This systematic review showed that the long term, the ω3 PUFA supplementation decreased the ratio omega-6 / omega-3 reduced neuronal loss in experimental models of AD, as well as improved cognitive function. This effect was more evident in older mice compared to young mice, and compared with males females. Conclusions: These results indicate the importance of new clinical trials be conducted with long-term ω3 PUFA supplementation in patients with AD for possible associations correct dosages in the treatment.
