THE IMPACT OF VITAMIN A, D, AND B-GROUP DEFICIENCIES ON COGNITIVE DEVELOPMENT IN CHILDREN

Abstract

Childhood is the most critical ontogenetic stage of human life, during which the central nervous system develops intensively. Optimal nutrition and an adequate supply of micronutrients are essential for the formation of interneuronal connections, synaptic plasticity, and myelination processes. Vitamins act as biological catalysts and play a key role in neurotransmitter synthesis, antioxidant defense, and regulation of gene expression.
