WEDNESDAY, July 17, 2019 (HealthDay News) — The largest study of its kind, involving more than 2 million people across five countries, finds that autism spectrum disorders are 80% reliant on inherited genes. That means that environmental causes are responsible for just 20% of the risk.

In effect, children with autism seem to laugh when the urge strikes them, regardless of whether other people find a particular situation funny.

Can Aspergers be passed on genetically?

The exact cause of Asperger’s is unknown. While it is largely inherited, the underlying genetics have not been determined conclusively. Environmental factors are also believed to play a role.

What is the mildest form of autism?

High functioning autism describes “mild” autism, or “level 1” on the spectrum. Asperger’s syndrome is often described as high functioning autism. Symptoms are present, but the need for support is minimal.

What is the main cause of autism?

Genetics. Several different genes appear to be involved in autism spectrum disorder. For some children, autism spectrum disorder can be associated with a genetic disorder, such as Rett syndrome or fragile X syndrome. For other children, genetic changes (mutations) may increase the risk of autism spectrum disorder.

What age does autism usually show up?

ASD begins before the age of 3 and last throughout a person’s life, although symptoms may improve over time. Some children with ASD show hints of future problems within the first few months of life. In others, symptoms may not show up until 24 months or later.
