If you've read about PTSD and something about your own experience doesn't quite align, complex PTSD (CPTSD) might be the term you're looking for. The two conditions share core symptoms, however the way in which they develop is what differentiates them. PTSD is typically diagnosed following a stand-alone traumatic experience, while complex PTSD typically stems from repeated exposure to trauma overtime. Thispresents additional challenges that standard PTSD treatment does not always fully address. This page explains the difference between the diagnoses, and explores what it means when seeking treatment.
In short: PTSD may develop after a single traumatic event, while complex PTSD develops from prolonged or repeated trauma, such as childhood abuse, ongoing domestic violence, or sustained exposure to danger. Complex PTSD includes the core symptoms of PTSD, such as flashbacks and hypervigilance, alongside additional difficulties like emotional dysregulation, a persistently negative sense of self, and relationship difficulties. Treatment for complex PTSD at Hirondelle Private Hospital builds on our standard PTSD model of care, with modalities such as Internal Family Systems (IFS) therapy utilised to address long-standing trauma.
PTSD generally develops after a single traumatic event, such as an accident, assault, or a specific traumatic incident at work. Complex PTSD develops differently: resulting from trauma that was prolonged, repeated, or happened during childhood or another period when escape wasn't possible, such as ongoing abuse, sustained domestic violence, or extended exposure to danger.
Both conditions share the core symptoms of PTSD: flashbacks, nightmares, avoidance of reminders, and a heightened sense of threat or hypervigilance. Complex PTSD adds to that picture, often including:
Because complex PTSD carries these additional layers, treatment that focuses purely on the traumatic memory itself does not always address related symptoms or difficulties. Approaches that also work with self-concept and relational patterns, such as Internal Family Systems (IFS) therapy, are often considered alongside standard trauma-focused treatment for people with complex PTSD.This is part of why we've introduced IFS therapy as a treatment modality at Hirondelle.
Following an assessment, your psychiatrist will recommend a combination of the following, based on your specific symptoms and trauma history:
| Option | What it involves | Best suited to |
|---|---|---|
| Trauma and PTSD Support Program | Weekly outpatient group program over 8 weeks, covering sleep, grief, memory, anger and emotional regulation | PTSD or complex PTSD, alongside individual therapy in the community |
| IFS therapy | Sessions working with the different "parts" shaped by trauma | Complex or long-standing trauma, or where retelling the event in detail hasn't helped |
| Inpatient admission | Overnight hospital admission with 24-hour support | Acute symptoms, safety concerns, or stabilisation before commencing therapy in the community |

This page is here to help you understand the difference between PTSD and complex PTSD, not to diagnose either. Only a qualified health professional can confirm which best describes your experience, based on a full clinical assessment.

What's the main difference between PTSD and complex PTSD?
PTSD typically follows a single traumatic event, while complex PTSD develops from prolonged or repeated trauma and includes additional difficulties such as emotional dysregulation and a negative self-view.
Can complex PTSD be treated the same way as PTSD?
Standard PTSD treatment is often part of the picture, but complex PTSD usually benefits from approaches that also address self-concept and relationship patterns, such as IFS therapy.
Do I need a diagnosis before seeking treatment?
No. A referral for a psychiatric assessment is the starting point, and your diagnosis can be confirmed as part of that assessment.
Is IFS therapy only used for complex PTSD?
IFS therapy is most often recommended for complex or long-standing trauma, but your psychiatrist will confirm whether it's the right fit for you specifically.
Understanding whether you're dealing with PTSD or complex PTSD is the first step toward the right treatment. Hirondelle Private Hospital offers trauma-focused therapy, our PTSD support program, IFS therapy and inpatient care where needed, all coordinated by a multidisciplinary team. Talk to your GP about a referral, or contact our Admissions Team to find out what treatment could look like for you.
