Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a developmental disorder that affects learning, language, and/or behavior, beginning in childhood.

The autism “spectrum” means there are many differences in the number and types of symptoms, seriousness, age of onset, and levels of functioning from person to person.

Some people on the autism spectrum display very few symptoms, while others may display many symptoms. Symptoms may include:

  • Trouble with social communication and social interaction.
  • Restricted patterns of behavior, interests, or activities.
  • Sensory processing difficulties.
  • Anxiety.
  • Hyperactivity.
  • Behavioral challenges (physical aggression, verbal aggression, property destruction, tantrums, and/or self-injurious behaviors).

Children diagnosed with ASD typically display symptoms at an early age. Therefore, when parents have any concerns about their child’s development, early evaluation and diagnosis are strongly recommended.

Early symptoms of autism spectrum disorder may include:

  • Disconnection to others.
  • Lack of interest in interacting with others.
  • Delayed development of language.

Individuals who meet the diagnostic criteria for ASD receive a diagnosis of autism spectrum disorder level 1, level 2, or level 3.
