Nutritional cognitive neuroscience of aging: Focus on carotenoids and cognitive frailty.

The term nutritional cognitive was recently established to define a research field focusing on the impact of nutrition on cognition and brain health across the life span. In this overview, we summarize the robust evidence on the role of carotenoids as micronutrients with different biological properties in persons with cognitive (pre)frailty. As neurodegenerative processes during occur in a continuum from brain to dementia, we propose the name nutritional cognitive neuroscience of aging to define research on the role of nutrition and micronutrients in cognitive frailty. Further studies are warranted which integrate carotenoid interventions in multidomain, personalized lifestyle strategies.
