Genetic theories refer to explanations that attribute the onset of neurodevelopmental disorders to genetic factors. These theories suggest that certain genes or combinations of genes contribute to the development of these disorders.
Environmental factors include non-genetic influences such as prenatal exposures, toxins, stress levels, and social experiences that can interact with genetic factors to contribute to neurodevelopmental disorders.
Epigenetics refers to modifications in gene expression caused by environmental factors without changing the underlying DNA sequence. It explores how external factors influence gene activity and can play a role in the development of neurodevelopmental disorders.
Gene-environment Interaction: This term describes the interplay between genetic predispositions and environmental influences. It suggests that both genetics and environment work together in shaping the occurrence and severity of neurodevelopmental disorders.
