How is Autism Spectrum Disorder (ASD) Diagnosed?

How is Autism Spectrum Disorder (ASD) Diagnosed?

Diagnosing autism spectrum disorder relies more on observation of certain behaviors and understanding the developmental history of the child. There are no medical autism spectrum tests to measure a person’s level of ASD. Doctors must rely on screenings, observations, and evaluations from:

  • Physicians
  • Psychologists
  • Speech pathologists
  • Mental healthcare professionals

ASD can be detected at about 18 months old. By the age two, an experienced professional can often make a reliable diagnosis. However, some children are diagnosed at a much later age. The earlier a child is diagnosed with ASD, the sooner they can receive individualized support to help them develop and learn.

How Do We Support Individuals with Autism Spectrum Disorder?

Interventions

Therapy for people with ASD is designed specifically for their needs. Each person has different strengths and weaknesses, therefore, intervention should be unique to their needs. How information is presented to an autistic individual is also an important aspect of their therapies and can help encourage self-advocacy.
These are some of the interventions used to help support people with ASD.

  • Applied Behavioral Analysis or other behaviorally-based intervention – These approaches utilize scientific principles of behavior to increase target behaviors and decrease harmful behaviors (e.g., self-injury).
  • Speech and language therapy – Speech and language therapy can include focusing on expanding knowledge and use of words, as well as on the social aspects of language such as conversational skills.
  • Occupational therapy – Occupational therapy (OT) includes skills needed for independent living like dressing, eating, bathing, and communicating with people. OT may help with sensory differences and fine motor skills (e.g., writing).
  • Sensory integration therapy – This helps to improve responses to sensory habits which may be restrictive or overwhelming.
  • Physical therapy – This therapy focuses on improving physical skills and strength.
  • Educational therapies – School settings should reflect a child’s individual strengths and weaknesses and may include a behavioral focus, a smaller classroom setting, and/or an emphasis on visual learning.
  • Social therapies – These treatments are designed to improve social skills and build emotional bonds.
  • Medications –There are no medicines designed specifically for ASD, however, other medications can manage other associated symptoms such as hyperactivity, self-injury, anxiety, or depression.
  • Cognitive behavior therapy – This psychological approach helps people with ASD deal with depression, feelings of anxiety, or just dealing with their thoughts.

Clinical trials are recommended to provide up-to-date treatment options and support for families of those with ASD. NewYork-Presbyterian participates in research studies that help advance our understanding of autism. These clinical trials lead to better treatments and enhanced education.
Patients who participate in NewYork-Presbyterian clinical trials for ASD receive the highest quality assessments and intervention services at no cost, and sometimes with compensation. Our research participants are helping redefine diagnostic assessments for ASD.
