Causes of delayed speech development in young children: theory and practice

Delayed speech development is one of the most common problems of modern childhood. The aim of this study is to theoretically analyze the causes of the indicated pathology in young children and to confirm the findings through empirical research. Using an interdisciplinary approach, scientific publications on the topic are analyzed. The factors influencing the formation of a child’s speech during infancy and early age are considered. Psychophysiological aspects have been analyzed, the relationship between the development of brain structures and the central nervous system has been established. An empirical study was conducted, which revealed that the causes of delayed speech and sensorimotor development of the child are due to harmful factors that have a negative impact on the fetus formation during gestation. It is deemed that their impact is particularly dangerous during the first trimester of a woman’s pregnancy, as it increases the risks of abnormalities in the child's speech development.
