Nutrients play an important role in the development of the brain and its cognitive domains. An insufficiency of nutrients in adults does not cause specific neurological damage, but among children, it may lead to problems associated with health, psychological behaviour and academic learning.

This review highlights the role of various nutrients in the cognitive development of a child, as well as various measures to overcome nutrient deficiencies among children.
