Autism spectrum disorders are a group of developmental disorders that affect communication and behavior. Though autism can be diagnosed at any age, it is known as a developmental disorder because the symptoms generally appear during the first two years of the child’s life.
Children with the autism spectrum disorder usually manifest difficulty to communicate or interact with other people, they show restricted interests and repetitive behaviors, and have a limited ability to perform at school and in other areas of their lives.
Autism disorder is known as a spectrum because there is a wide range of variation in the type or severity of the symptoms manifested by those affected by this disorder.
