The Raise of Neurodevelopmental Disorders (NDS): From Genetics to Epigenetics.

NDs are a collection of disorders that appear in the early stages of development and are variously associated with cognitive and behavioral dysfunctions. The strong heritability of these conditions (in particular autism and schizophrenia) argues in favor of a genetic origin. On the other hand, the massive increase in NDs implies a preponderant role of environmental factors and epigenetic mechanism (Panisi et al. 2021).
