Omega-3 fatty acids enhance cognitive flexibility in at-risk older adults
A study of older adults at risk of late-onset Alzheimer's disease found that those who consumed more omega-3 fatty acids did better than their peers on tests of cognitive flexibility -- the ability to efficiently switch between tasks -- and had a bigger anterior cingulate cortex, a brain region known to contribute to cognitive flexibility.
The new study focused on 40 cognitively healthy older adults between the ages of 65 and 75 who are carriers of a gene variant (APOE e4) that is known to contribute to the risk of developing late-onset Alzheimer's disease.
'We wanted to confirm that higher omega-3 fatty acids related to better cognitive flexibility, and we did in fact see that,' Zamroziewicz said. 'We also wanted to confirm that higher omega-3 fatty acids related to higher volume in the anterior cingulate cortex, and we saw that. Finally, we were able to show that higher volume in the anterior cingulate cortex was an intermediary in the relationship between omega-3 fatty acids and cognitive flexibility.'

Ain't nobody at a higher risk for LOAD than we are, right? This is about US, dear hearts. Pass the purest salmon, highest-quality krill oil supplement, and algae-derived omega-3 supplement, please.
