Important Information About Autism

It’s important to understand that Autism Spectrum Disorder (ASD) is not categorized by different levels anymore. Previously, the Diagnostic and Statistical Manual of Mental Disorders (DSM-4) was used to classify autism into subcategories with labels like Asperger’s syndrome (considered mild autism) or Autistic Disorder (considered severe autism). However, this system is no longer used.

The current system, outlined in the DSM-5, diagnoses ASD and assigns a support level (Level 1, 2, or 3) based on two main areas:



  1. Social communication challenges
  • This includes difficulties with social interaction, nonverbal communication, and developing and maintaining relationships.
  1. Restricted, repetitive behaviors or interests
  • This encompasses repetitive movements, routines, intense fixations on specific interests, and sensory sensitivities.

The support level assigned indicates the amount of support an autistic person needs in daily life,  focusing on how much their traits impact their ability to function in various settings. Here’s a breakdown of the support levels:

  • Level 1: Requires minimal support. Individuals may struggle with social interaction and communication or have repetitive behaviors, but they can generally manage their daily lives independently.
  • Level 2: Requires substantial support. Individuals have significant challenges in social communication and may need help with daily living activities or managing their emotions.
  • Level 3: Requires very substantial support. Individuals have severe limitations in social communication and may require extensive assistance with all aspects of daily living.

It’s important to remember that these levels are guidelines, and the autism experience is highly individual. Someone might need more support in one area (like social communication) and less in another (like daily living skills).

Things You Need to Know About Autism

  1. Autism Spectrum Disorder (ASD) isn’t a single condition but rather a spectrum. This means people with autism experience a range of challenges and strengths in varying degrees.
  2. People with autism often face difficulties with social interaction and communication. This can involve challenges like making eye contact, understanding nonverbal cues, or engaging in back-and-forth conversation.
  3. Many autistic people engage in repetitive behaviors or are intensely interested in specific topics. This can be anything from lining up toys to being fascinated by dinosaurs. While repetitive behaviors can sometimes appear disruptive, they often provide comfort and predictability for autistic individuals.
  4. The world can be an exceptionally sensory place for autistic people. They might be oversensitive to certain sounds, lights, textures, or tastes. This can make everyday situations overwhelming for some autistic individuals.
  5. It’s important to remember that autism is not a disease but a developmental difference. Autistic people process information differently, and their brains function in unique ways.
  6. Autism affects everyone differently. Some autistic people have intellectual and developmental disabilities, while others have average or even superior intelligence. There isn’t a single “autistic personality.”
  7. Early intervention is crucial for autistic children. Therapies and support systems can help them develop communication social skills, and manage sensory sensitivities.
  8. The support needs of autistic individuals vary greatly.  Some may require extensive support throughout their lives, while others may lead more independent lives with some assistance.
  9. Creating a more accepting and inclusive world is essential for autistic people. This involves celebrating neurodiversity, providing access to resources and opportunities, and fostering empathy and understanding.
