Cognitive Decline and Vitamins.

Abstract

Dementia and cognitive decline are concerning conditions, especially because they coincide with great uncertainty and have no cure. Scientists continue to explore these conditions in order to better understand their causes and identify potential treatments. Numerous interventions have been studied, from various diets to medications, supplements, and vitamins. There are many scientific and nonscientific articles that discuss what may lead to these conditions and how to address them. However, researchers are still trying to understand the actual and complex causes of dementia and cognitive decline; the available medications primarily focus on symptoms but do not "cure" the conditions (and also come with their own controversies); and much of the nonscientific literature contains recommendations that are not supported by strong empirical evidence. This article briefly reviews the data about how vitamin B and E in dementia and cognitive decline.
