One of the main indicators determining the potential of a nation is the health of its younger generation. The present study was conducted in a kindergarten in Karaganda, Kazakhstan. 139 children (their age ranged from 4 years to 5 years and 5 months) were the participants of this study who were divided into two groups of children with neurosis and a group of healthy children. The results indicated that the lack of essential metals in children with neuroses explained one of the mechanisms of the pathogenesis of neurotic disorders, and was associated with a violation of the processes of their absorption in the intestine, due to chronic stress. The article discussed the results of a study aimed at identifying the bio-elemental status in children with different levels of neuroticism. Further research studies including various regions and ages are needed in order to identify the factors affecting the elemental status of normally developing preschool children.
