People with severe autism would usually be diagnosed as having level 3 autism spectrum disorder, meaning they need a great deal of support. It is not unusual for a person with severe autism to require 24/7 support and supervision. Severe autism can be much more debilitating and challenging than other types of autism.
What is the most severe form of autism?
Autistic disorder was the most severe. Asperger’s Syndrome, sometimes called high-functioning autism, and PDD-NOS, or atypical autism, were the less severe variants. Childhood disintegrative disorder and Rett Syndrome were also among the pervasive developmental disorders.
What is the difference between mild and severe autism?
Depending on intellectual abilities, children with moderate autism may learn to communicate through pictures, typing, or via other communication devices. Many children with severe autism have very limited communication and language abilities.
What causes severe 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.
Does severe autism get better with age?

ASD has a tendency to run in families, but the inheritance pattern is usually unknown. People with gene changes associated with ASD generally inherit an increased risk of developing the condition, rather than the condition itself.
What age does autism usually show up?
Some children show ASD symptoms within the first 12 months of life. In others, symptoms may not show up until 24 months or later.
