[The role of dietary factors in cognitive decline].

The increasing morbidity and mortality of dementia places a significant burden on society in economic, social and health terms. In addition to the therapy of partially detectable etiologies, diet can also play a major role in reducing the risk of dementia. The most commonly studied dietary patterns in relation to cognitive decline are the Mediterranean diet, the DASH (Dietary Approaches to Stop Hypertension) diet for the prevention of hypertension, and the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet, which has emerged as a new approach in the last decade, combining elements of the Mediterranean and DASH diets, but there is also considerable research on the ketogenic diet and intermittent fasting.
