I can not find much research that supports the theory that Omega-3s accelerate brain aging. A recent study I have come across regarding brain aging and Omega-3's is, "Red blood cell omega-3 fatty acid levels and markers of accelerated brain aging". It suggests that Participants with lower DHA and ω-3 index (RBC DHA+EPA) levels also had lower scores on tests of visual memory (β ± SE = −0.47 ± 0.18;
p = 0.008), executive function (β ± SE = −0.07 ± 0.03;
p = 0.004), and abstract thinking (β ± SE = −0.52 ± 0.18;
p = 0.004)", thus supporting the theory that Omega-3 protects the brain from age related changes rather than impairs it. For a full read, the article can be found at:

Similar findings have been reported in most of the scientific journals I have read. Feel free to pass along research that reports different findings as I am interested in reading them.
For interest sake, I just found out that Omega-3 and Omega-6 have been added to all prenatal vitamins to aid in brain development. It is also used as a supplemental treatment for Alzheimer.
Gotta go... I too am jumping on the Omega bus! Save me a seat!
