Understanding Trauma in Neurodivergent People

Neurodiversity refers to the natural differences in how people think, communicate, process information, and experience the world. It includes neurodevelopmental differences such as autism, ADHD, dyslexia, and dyspraxia. Being neurodivergent is not a trauma response, and it does not mean that someone will develop trauma-related difficulties. However, research suggests that autistic and neurodivergent young people may experience higher levels of adversity and victimisation than their neurotypical peers.

For example, research involving more than 11,000 secondary school students found that neurodivergent adolescents were more likely to report bullying, peer abuse, physical harm at school, and maltreatment. These experiences were associated with poorer mental health, while neurodivergent adolescents showed poorer mental health overall, including when they had not experienced these particular adversities (Quinton et al., 2025).

Trauma can also involve experiences that are not always captured by conventional trauma questionnaires. Research with autistic people has identified experiences such as feeling trapped, loss of autonomy, social exclusion, bullying, stigma, sensory difficulties, transitions, and social confusion as potentially distressing or traumatic experiences (Kerns et al., 2022). Importantly, this does not mean that these experiences automatically meet the diagnostic criteria for PTSD. Rather, it highlights the importance of understanding how each person experiences and responds to what has happened to them.

Recognising Trauma in Neurodivergent People

One of the challenges in recognising trauma in autistic people is that some characteristics of autism and trauma-related symptoms can look similar. Sensory sensitivity, sleep difficulties, repetitive behaviours, social withdrawal, difficulties with communication, concentration problems, or changes in behaviour may occur in both autism and trauma-related difficulties.

This can sometimes lead to diagnostic overshadowing, where trauma-related symptoms are attributed to autism rather than recognised as a possible response to trauma. The opposite can also happen, with autism being overlooked when a child’s difficulties are attributed entirely to trauma. The distinction is therefore not always “autism or trauma”; for some people, it may be both.

Changes from a person’s usual pattern of behaviour can be particularly important. For example, a young person who becomes significantly more withdrawn, experiences new sleep difficulties, loses previously established communication or self-care skills, or shows increased aggression or repetitive behaviour following an adverse experience may be communicating distress in ways that are not immediately recognised as trauma-related.

For this reason, understanding the person’s developmental history and their usual way of functioning can be an important part of assessment. Looking at what has changed, rather than only at what the person is doing now, can help clinicians better understand whether trauma may be contributing to their difficulties.

A Trauma-Informed and Neurodiversity-Affirming Approach

Supporting a neurodivergent person who has experienced trauma requires attention to both areas. Trauma-informed care emphasises safety, trust, choice, collaboration, and empowerment. For autistic people, these principles may be strengthened by making environments more predictable, reducing unnecessary sensory demands, providing clear communication, offering quiet spaces, and allowing appropriate opportunities for self-regulation.

The aim is not to change or “normalise” the neurodivergent person. Instead, a neurodiversity-affirming approach recognises that support and therapeutic interventions themselves may need to be adapted to meet the individual’s cognitive profile, communication style, sensory needs, and ways of understanding and experiencing the world.

Adaptation should therefore be considered across all aspects of support and intervention. This may involve adapting the pace and structure of sessions, communication style, therapeutic materials, and expectations to make them accessible and meaningful for the individual.  Clear and literal communication, predictable routines, advance notice of changes, sensory-friendly spaces, visual supports, and opportunities for self-regulation may all form part of this process. This is central to ensuring that care is genuinely neurodiversity-affirming

Trauma-focused psychological therapies may also be appropriate when PTSD is present. However, the evidence base for trauma treatment specifically in autistic people remains limited. Research has found promising early evidence for approaches such as EMDR and trauma-focused CBT, although more research is needed to understand how these therapies can best be adapted for autistic children and young people.

The central message is that neurodiversity and trauma should not be considered in isolation. Autistic and neurodivergent young people may face increased exposure to adversity, while trauma-related symptoms can sometimes be difficult to distinguish from neurodevelopmental characteristics.

A careful assessment that considers developmental history, changes from baseline, the person’s own experience, and their environment can help reduce the risk of difficulties being missed or misunderstood. Support that is both trauma-informed and neurodiversity-affirming can help create the conditions in which a person feels safe, understood, and supported.
