what age can a person get autism
Doctors look at the childâs behavior and development to make a diagnosis. ASD can sometimes be detected at 18 months or younger. By age 2, a diagnosis by an experienced professional can be considered very reliable. However, many children do not receive a final diagnosis until much older.This delay means that children with ASD might not get the early help they need.owever, research shows that early intervention treatment services can improve a childâs development. Early intervention services help children from birth to 3 years old (36 months) learn important skills. Services can include therapy to help the child talk, walk, and interact with others.
