What is Autism?

What Is Autism?

An Information Sheet for Adults & Teens

Most descriptions of autism focus on stereotypes — social skills, eye contact, or behaviour.

This information sheet offers something different.

“What Is Autism?” explains autism through a nervous system lens, helping you understand why autistic people experience the world the way they do — not just how it looks from the outside.

It’s written for clarity, recognition, and reassurance, without overwhelm.

🌱 What this resource is

This information sheet is:

• a clear, accessible explanation of autism
• written in validating, non-clinical language
• grounded in lived experience, not deficits
• focused on understanding, not diagnosis

It is not:

• a diagnostic tool
• a symptom checklist
• a behaviour guide
• a replacement for professional assessment

This resource is about recognition, not labels.

🧠 What it covers

• autism as a nervous system difference
• sensory processing and regulation
• overwhelm, shutdown, and withdrawal
• the role of predictability and safety
• masking and late recognition
• anxiety in autistic adults
• PDA and autonomy-based nervous system responses

Written so readers can say:
“This explains how my body experiences the world.”

👤 Who this is for

• autistic adults seeking clearer understanding
• teens exploring whether autism resonates
• people awaiting or questioning diagnosis
• parents and supporters wanting a deeper explanation
• anyone wanting an autism explanation beyond stereotypes

You do not need a diagnosis for this resource to be helpful.
