For CliniciansAutism spectrum disorders (ASDs) are a group of neurodevelopmental disorders characterized by impaired social interaction and communication and by restricted or repetitive behaviors. Symptoms of an ASD usually appear before the age of 3 years and can be accurately diagnosed by 2. Early, accurate diagnosis can lead to timely referral for effective intervention which is directly associated with gains in verbal and nonverbal communication, higher intelligence test scores, and improved social interaction.
