This is one of the first studies to explore the effects of omega-3s on cognition and brain physiology. 

In the study, doctors divided 166 participants into low- and high-levels of the omega-3s EPA and DHA. Researchers then scanned 128 regions of each participant’s brain, and everyone completed computerized tests of memory and cognition. 

As blood flow to the brain—and levels of omega-3s in the brain—increased, participants did better on tests of cognition and memory. Doctors said the findings revealed a direct link between lower omega-3 levels and reduced brain blood flow to regions important for learning, memory, depression, and dementia.
