Autism Spectrum Disorder Fact Sheet

Autism spectrum disorder (ASD) refers to a group of complex neurodevelopment disorders characterized by repetitive and characteristic patterns of behavior and difficulties with social communication and interaction. The symptoms are present from early childhood and affect daily functioning.

The term “spectrum” refers to the wide range of symptoms, skills, and levels of disability in functioning that can occur in people with ASD. Some children and adults with ASD are fully able to perform all activities of daily living while others require substantial support to perform basic activities. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5, published in 2013) includes Asperger syndrome, childhood disintegrative disorder, and pervasive developmental disorders not otherwise specified (PDD-NOS) as part of ASD rather than as separate disorders. A diagnosis of ASD includes an assessment of intellectual disability and language impairment.


First Signs

First Signs is dedicated to educating parents and professionals about autism and related disorders.

With developmental, behavioral, and learning disabilities on the rise, there is much that remains poorly understood, from cause to cure. However, there is one widely accepted fact: early and intensive intervention can have a profound impact on the quality of life for children at risk and their families. The key is early detection. But recognizing the early signs can be a challenge for parents and healthcare professionals alike.


Learn the Signs. Act Early.

From birth to 5 years, your child should reach milestones in how he plays, learns, speaks, acts and moves. Track your child’s development and act early if you have a concern.
