5. Conclusions
memory complaints, dementia, cognitive decline
No clear effect was detected for LCPUFAs + LZ on memory function in healthy older Japanese individuals with memory complaints without dementia. Further investigation, including evaluation using other memory assessments, is needed to determine the effect of LCPUFAs + LZ as an intervention. In contrast, supplementation with LCPUFAs + LZ improved memory function in healthy older Japanese individuals with cognitive decline without dementia. Future interventional studies based on a detailed understanding of the cognitive function status of the participants at baseline will lead to appropriate judgments of the intervention’s effect on memory function.
