In older Japanese women, higher blood DHA levels—but not EPA levels—were associated with greater gray matter brain volume.
This review summarizes evidence that omega-3 fatty acids like DHA and EPA may influence brain inflammation, protein buildup, and cognitive markers linked to Alzheimer's disease, though results across studies remain mixed.
Older adults with higher blood DHA+EPA levels showed larger gray matter volume and lower amyloid-beta buildup in Alzheimer's-related brain regions.
