EVALUATION OF THE EFFECTS OF PRENATAL EXPOSURE TO TOXIC SUBSTANCES ON CHILD NEUROLOGICAL DEVELOPMENT

Abstract

Prenatal exposure to toxic substances has been associated with a number of adverse effects on infant neurological development. In this study, behavioral, cognitive, motor and structural changes were investigated, as well as neural and epigenetic dysfunctions, in addition to vulnerability to neurological disorders resulting from this exposure. The integrative analysis of epidemiological and experimental studies revealed that exposure to toxic substances during pregnancy is correlated with attention deficits, hyperactivity, learning difficulties, impaired motor coordination, changes in brain connectivity and changes in gene expression. Mechanisms such as interference with neurotransmission, inflammation and oxidative stress have been identified as mediators of these effects. In addition, prenatal exposure to toxic substances increased vulnerability to neurological disorders, including autism spectrum disorder, attention deficit hyperactivity disorder, as well as anxiety and depression disorders. These results underscore the need for robust preventive strategies, targeted interventions, and long-term monitoring programs to mitigate the risks associated with toxic exposure during childhood neurological development. An in-depth understanding of the underlying mechanisms and clinical implications of these effects is essential to inform public health approaches and therapeutic interventions designed to protect the health and well-being of future generations.
