DHA y funcionamiento cerebral: ¿Cuáles son los beneficios?

Docosahexaenoic acid (DHA) is an omega-3 long chain polyunsaturated fatty acid. It is obtained from exogenous sources as fish oils that process it from algae consumed by the fish, whereas the inner source is processed from other fatty acids. The brain and the retina are the organs with major concentration of DHA and its pr incipal functions are as membrane component and energy source. Some studies on animal models demonstrated that DHA inhibits tau protein formation and amyloid plaque in models of Alzheimer disease, whereas its deficiency produces an impaired performance in cognitive and behavioral tests. On the other hand, the human studies show that an active transport exists from prenatal stage, and the ability of transformation from other fatty acids is maintained throughout life. Other studies suggest that DHA participates in neurogenesis, neurotransmission and protection against oxidative stress. The evidence supporting supplementation in different stages of the human life has been controversial, having as the main objective the improvement of intellectual performance dur ing chi ldhood and maintenance or improvement of memory in adulthood, when mild REVISION NEUROLOGICA
