Researchers from the Amen Clinic in California and the University of South Dakota School of Medicine have published a study relating omega-3 fatty acid blood levels, SPECT perfusion scanning, and memory and cognition.[1]

They used a random sample of 166 individuals from a psychiatric referral clinic.

They measured the omega-3 index, which includes serum concentrations of EPA and DHA, and divided the group into those with > 50th percentile levels and those with < 50th percentile levels.

Both groups received quantitative brain SPECT scans on 128 cortical regions and completed a battery of computerized cognitive testing.

Their results showed a statistically significant relationship between omega-3 EPA + DHA status, hippocampal brain perfusion, and scoring on memory testing.

The researchers concluded that this positive relationship means that relatively simple dietary changes could favorably impact cognitive functioning.
