The different causes of trauma for autistic people are shown in this graphic from a study of 59 Autistic adults – 36 female and 23 male (Rumball, Happe & Grey, 2020). The information is important because one of our two international diagnostic systems (Diagnostic Statistical Manual (DSM), which is widely used in Australia, does not recognise these events as being traumatic for people. Clinicians using the DSM would not diagnose these adults as having possible Post-Traumatic Stress Disorder (PTSD), which means that they would likely not receive help for their PTSD.
Dr Freya Rumball not only found that autistic adults experienced a wide range of life events as traumatic, but also that over 40% showed probable PTSD within the last month and over 60% reporting probable PTSD at some point in their lifetime. The association between autism and trauma is a source of current research investigation and concern because these rates are far higher than those in the typical population.

We have developed a full-day course on Trauma and Autism, to be webcast live on Friday 17 January 2026.
This session explores how trauma presents in autistic children, teenagers, and adults, and how their unique neurology can shape both vulnerability and resilience. Drawing on recent, evidence-based research, lived experience, and over 80 years of combined clinical experience, it focuses on understanding trauma through an autistic lens and providing pathways for sensitive, compassionate support.
