Fish oil's impact on cognition and brain structure

Researchers have found positive associations between fish oil supplements and cognitive functioning as well as differences in brain structure between users and non-users of fish oil supplements. The findings suggest possible benefits of fish oil supplements on brain health and aging.

 

Daiello says, "In the imaging analyses for the entire study population, we found a significant positive association between fish oil supplement use and average brain volumes in two critical areas utilized in memory and thinking (cerebral cortex and hippocampus), as well as smaller brain ventricular volumes compared to non-users at any given time in the study. In other words, fish oil use was associated with less brain shrinkage in patients taking these supplements during the ADNI study compared to those who didn't report using them."

 

Daiello continues, "These observations should motivate further study of the possible effects of long-term fish oil supplementation on important markers of cognitive decline and the potential influence of genetics on these outcomes."
