The difficult behaviors seen in autistic toddlers tend to improve between ages 6 and 10. Problems may resurface during the teen and young adult years. They eventually calm down again in middle and later life.
Some children with autism are able to live independently. Others may struggle to maintain normal social interactions, communication and behaviors.
Experts believe earlier ASD diagnosis and treatment leads to a better outcome.
Life expectancy depends on whether the person has other conditions and the person's overall health.
