What really causes autism
Where Does Autism Come From?
Studies indicate that autism spectrum disorder (ASD) arises from a blend of genetic and environmental factors, encompassing social determinants. These elements contribute to the likelihood of autism and influence the specific subtype that a child may exhibit. However, it’s crucial to distinguish between heightened risk and causation. For instance, certain genetic variations linked to autism may also be present in individuals without the disorder. Likewise, exposure to environmental risk factors doesn’t guarantee the development of autism; in fact, the majority will not.
What role do genetic and environmental factors play in the development of autism?
Many factors seem to impact critical facets of early brain development. Numerous genes associated with autism influence broader networks of genes, either amplifying or diminishing their activity. Some of these genes affect the communication between individual neurons in the brain, while others influence communication between entire brain regions. Ongoing research is dedicated to understanding these variances, with the aim of developing interventions and supports to enhance quality of life.
