The incidence of Alzheimer’s disease (AD) is expected to triple in the coming decades and no cure has been found. Omega-3 fatty acids have shown anti-amyloid, anti-tau and anti-inflammatory actions in the brains of animals. In a new article published in the Journal of Alzheimer’s Disease, researchers have found that for patients with high omega-3 levels, blood flow in specific areas of the brain is increased.
This study drew from a random sample of 166 participants from a psychiatric referral clinic for which Omega-3 Index results were available. Quantitative brain SPECT was conducted and each participant completed computerized testing of their neurocognitive status. Results indicated statistically significant relationships between the Omega-3 index, regional perfusion on brain SPECT in areas involved with memory, and neurocognitive testing.
