Abstract

fetched live from OpenAlex

An international expert panel convened to evaluate nutrition-based approaches to brain health and dementia prevention. This consensus statement integrates perspectives from lived experiences, mechanistic evidence, epidemiology, and clinical interventions. Nutrition plays a crucial role in brain health throughout life and in cognitive decline pathogenesis, particularly through the food-gut-brain axis. Intervention effectiveness varies across the health promotion, prevention, treatment, and maintenance spectrum due to methodological differences and individual responses to nutritional interventions.The Mediterranean and MIND dietary patterns show promise for maintaining cognitive function across studies. Multi-domain interventions like FINGER effectively combine dietary modifications with lifestyle changes to delay dementia onset in at-risk older adults. These findings align with mechanistic evidence on the food-gut-brain axis in maintaining optimal brain health by preventing neurodegeneration. Key mechanisms include gut microbiota composition and function, blood-brain barrier integrity, endothelial and mitochondrial dysfunction, insulin resistance, oxidative stress, and inflammatory processes.Research priorities include standardizing cognitive assessment methodologies, developing early intervention strategies, and implementing integrated precision nutrition and lifestyle approaches. Incorporating patients' and caregivers' lived experiences in research co-production was identified as essential to support those with lived experience. The panel concluded that future directions should combine population and individual-level preventive approaches while addressing challenges in sustaining healthy behavioral changes and understanding the complex interplay between diet, lifestyle, and genetic factors in brain health and dementia prevention. Experts emphasized the need for both standardized methodologies and personalized interventions to account for individual variability in nutritional responses and facilitate effective prevention strategies across diverse populations.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
