Nutrition for dementia prevention: a state of the art update for clinicians

Background and objectives: Dementia prevalence continues to rise. It is therefore essential to provide feasible and effectiverecommendations to encourage healthy brain ageing and reduce dementia risk across the population. Appropriate nutritionrepresents a potential strategy to mitigate dementia risk and could be recommended by clinicians as part of mid-life healthchecks and other health initiatives to reduce dementia prevalence. The purpose of this review is to provide a clinician-focusedupdate on the current state of the knowledge on nutrition and dementia prevention. 
Methods: Narrative review. 
Results: Strong evidence exists to support the consumption of healthy, plant-based dietary patterns (e.g. Mediterranean,MIND or Nordic diet) for maintaining cognitive function and reducing dementia risk in later life and is supported bydementia prevention guideline from leading public health bodies (e.g. World Health Organization). Emerging evidence sug-gests potential cognitive benefits of consuming specific nutrients/foods (e.g. n-3 fatty acids or fish, flavonols and B-vitamins)and multi-nutrient compounds (e.g. Fortasyn Connect). Challenges and opportunities for integrating nutritional/dietaryinterventions for dementia prevention into clinical practice are explored in this review. 
Conclusions: Appropriate nutrition represents an important factor to help facilitate healthy cognitive ageing and allaydementia risk. The information provided in this article can help clinicians provide informed opinions on appropriatenutritional strategies as part of mid-life Health Checks and other risk reduction initiatives.Keywords: older people, nutrition, dementia prevention, dietary change, risk reduction
