What is the main cause of autism?
There is no known single cause for autism spectrum disorder, but it is generally accepted that it is caused by abnormalities in brain structure or function. Brain scans show differences in the shape and structure of the brain in children with autism compared to in neurotypical children.
What disabilities are on the autism spectrum?
A diagnosis of ASD now includes several conditions that used to be diagnosed separately: autistic disorder, pervasive developmental disorder not otherwise specified (PDD-NOS), and Asperger syndrome. These conditions are now all called autism spectrum disorder.
Why is autism classed as a spectrum condition?

Which parent is responsible for autism?
Researchers have assumed that mothers are more likely to pass on autism-promoting gene variants. That’s because the rate of autism in women is much lower than that in men, and it is thought that women can carry the same genetic risk factors without having any signs of autism.
