Omega-3 fatty acids, specifically EPA and DHA, play a key role in several aspects of brain health including mechanisms involved in memory and cognition. In 2016, results from a study assessing the association between Omega-3 Index, a biomarker of EPA and DHA status, and cognitive decline among older adults were published. This study included 720 participants aged 68 to 92 years old and assessed four cognitive domains: orientation, memory, attention, and language.

What were the findings of the study?

Participants with the highest Omega-3 Index levels (greater than 6.8%) had a 44% lower risk of cognitive impairment compared to participants with the lowest Omega-3 Index levels (less than 5.7%) (P=0.01).

This association remained consistent after adjusting for sex, age, education, metabolic risk factors (obesity, hypertension, high cholesterol, smoking, and physical activity), depression, and anxiety.
