Facts About Autism
There are no observable physical features of autism and the symptoms of autism are reflected in deficits in social communication and interaction as well as repetitive behaviours.
Autism presents itself in early childhood (before 3 years old) and can be identified as early as 18 months old.
Autism is a spectrum disorder. This means that some individuals are affected by autism on a mild level, some on a moderate level and some on a severe level.
