Types of Trauma Disorders 

Not all trauma-related difficulties look the same.

Many people are confused about the differences between PTSD, Occupational PTSD, Complex Trauma, and Borderline Personality Disorder. While these conditions can share some symptoms, they often develop from different life experiences, affect people in different ways, and may require different treatment approaches.

This practical comparison handout provides a side-by-side overview of four commonly misunderstood trauma-related presentations. Designed by Jess O'Garr (Clinical Psychologist) and Dr Al Griskaitis (Psychiatrist), it helps make sense of how trauma can influence emotions, relationships, identity, behaviour, and recovery.

In this resource, you'll learn:

✔ The key differences between PTSD, Occupational PTSD, Complex Trauma, and Borderline Personality Disorder

✔ How different trauma experiences can shape symptoms and coping styles

✔ Why attachment experiences and childhood environments matter

✔ How re-experiencing, avoidance, hypervigilance, and emotional regulation differ across presentations

✔ The impact of trauma on identity, self-concept, and relationships

✔ Common evidence-based treatment approaches for each presentation

This handout is ideal for people wanting to better understand their own experiences, support a loved one, or learn more about trauma-related diagnoses in a clear and accessible format.

Whether you're newly exploring trauma, currently engaged in therapy, or looking for a simple reference guide, this resource provides a practical framework for understanding the many ways trauma can affect people's lives.
