Despite extensive research, the precise causes of autism spectrum disorder (ASD) have not been identified. However, current evidence strongly suggests that the disorder's development is influenced by a combination of genetic predispositions and environmental factors.

Factors Contributing to the Development of Autism Spectrum Disorder

Genetics play a significant role in the development of autism spectrum disorder. Evidence from twin studies highlights this, showing concordance rates of 60-90% for identical twins, compared to just 5-10% for fraternal twins and siblings. Research has implicated numerous genes and mutations, particularly those involved in creating synaptic circuits that enable communication between different brain regions.

Genetic Influences on Autism Spectrum Disorder

Various environmental factors are believed to be associated with a higher risk of developing autism spectrum disorder. It is thought that these factors may contribute, at least partially, by causing new genetic mutations.
