ABSTRACT

Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders characterized by social communication disorders,narrow interest and repetitive behavior,which has an early childhood onset,resulting in high disability.The etiology of autism spectrum disorder is unknown and the prognosis is poor.There is no specific medication at present.Early diagnosis and intervention can improve the symptoms and prognosis of children with autism spectrum disorder.However,due to the lack of awareness of autism spectrum disorder among some medical staff and parents,the diagnosis and treatment of children are often delayed.This article reviews the early behavioral characteristics,screening tools,laboratory tests,diagnostic criteria,and the impact of early intervention on children with autism spectrum disorder,providing reference for early identification and intervention of children with autism spectrum disorder.
