Examining the efficacy of the Mediterranean-DASH diet intervention for neurodegenerative delay in mitigating cognitive decline

Abstract

Abstract Background The association between the Mediterranean-DASH (Dietary Approaches to Stop Hypertension) Diet Intervention for Neurodegenerative Delay (MIND) diet and cognitive decline has garnered substantial attention in recent research. This review aims to comprehensively analyse the existing evidence regarding the potential impact of the MIND diet on cognitive health. Methods A literature search was conducted to identify relevant studies exploring the relationship between the MIND diet and cognitive decline. A narrative synthesis approach was employed to summarise and interpret the findings from diverse study designs. Results The review reveals consistent evidence suggesting a positive association between adherence to the MIND diet and improved cognitive performance. Several longitudinal studies demonstrate potential preventive effects against cognitive decline, emphasising the significance of dietary habits in preserving cognitive function. Conclusion The MIND diet's positive impact on cognitive health is well-supported by numerous studies. Additionally, the review highlights the exciting opportunity to connect research findings with practical dietary guidance and targeted interventions, particularly for high-risk populations, to enhance cognitive health promotion.
