Omega-3 Cognition Meta-AnalysisConcurrently, the number of individuals affected by dementia is anticipated to nearly triple by 2050, with associated treatment costs projected to reach US$2.8 trillion by 2030 [].1Liu Xing (2026)Nutritional supplements and cognition in healthy aging and mild cognitive impairment patients: a systematic review and network meta-analysis
Omega-3 Cognition Meta-AnalysisIn addition, omega-3 fatty acids support synaptic plasticity and exert anti-inflammatory effects; however, evidence is mixed, as randomized trials in healthy older adults show limited benefits [,], while several analyses report modest improvements in aged or MCI patients [,].1Liu Xing (2026)Nutritional supplements and cognition in healthy aging and mild cognitive impairment patients: a systematic review and network meta-analysis
Omega-3 Cognition Meta-AnalysisObservational studies and recent trials involving antioxidant nutrients, such as pomegranate juice and resveratrol, alongside polyphenols, suggest potential protection for specific cognitive domains (e.g., memory) and reduced dementia risk, although effects are heterogeneous and causality remains unconfirmed [,].1Liu Xing (2026)Nutritional supplements and cognition in healthy aging and mild cognitive impairment patients: a systematic review and network meta-analysis

Omega-3 Cognition Meta-AnalysisConsequently, identifying modifiable risk factors to prevent or delay cognitive decline is of critical public health importance [,].4Liao Zheng-Bin (2026)The association between omega-3 supplementation and cognitive decline in older adults
Omega-3 Cognition Meta-AnalysisBy elucidating these specific neurobiological pathways, we aim to provide clinical evidence that informs the debate regarding the role of omega-3 fatty acids supplementation in slowing cognitive decline.4Liao Zheng-Bin (2026)The association between omega-3 supplementation and cognitive decline in older adults
