Post-traumatic stress disorder (PTSD) and complex post-traumatic stress disorder (CPTSD) are both mental health conditions that come from experiencing traumatic situations. They share many of the same signs, yet they have some key differences. 

If you or a loved one have experienced trauma and are wondering about the similarities and differences between PTSD and CPTSD, this guide can help. It’ll break down the common experiences of each, as well as the causes, symptoms, and options for treatment.

What is PTSD?

PTSD is most often a result of experiencing one or just a few traumatic situations. This may mean experiencing the event yourself, watching someone else experience the event, or learning that something violent or accidental happened to someone close to you. 

The type of events linked to PTSD include exposure to death or threat of death, a serious injury, or sexual violence. Examples can include an experience during war, a car accident, sexual assault, or hearing the details about a loved one being attacked.

After experiencing an event like this, there are typically four categories of symptoms you’d notice:

  • Intrusive symptoms: This includes nightmares and/or flashbacks that feel like you’re actually reliving the event, or very strong memories of the experience.
  • Avoidance: You try to stay away from people, places, or things that remind you of the event. You may even try to avoid noticing the memories or feelings related to the event.
  • Negative changes in mood and thinking: This involves negative beliefs about yourself or the world around you, ongoing negative emotions (fear, shame, anger), unfairly blaming yourself or others for what happened, less interest in normal activities, or feeling less connected to positive emotions and other people.
  • Changes in alertness and reactivity: You may feel afraid or on edge, easily startled, more irritable or angry, engage in reckless behavior, or struggle to concentrate or sleep.

What is CPTSD?

The trauma behind CPTSD is often called complex trauma — harm that is repeated, lasts a long time, and usually happens in relationships or situations where you cannot escape or get help. These are situations where the events were harmful, threatening, or horrifying.

Childhood complex PTSD can develop when a child lives with ongoing abuse; other examples include someone in a violent or abusive relationship or a person held in trafficking. What makes it “complex” isn't just one event, but the ongoing nature of the harm and how it shapes the way you see yourself, other people, and the world.

If you lived through long-term harm, especially in childhood or close relationships, you may not think of what you went through as trauma because there wasn't one dramatic event. But ongoing, everyday harm can have real and lasting effects.

The symptoms of CPTSD include the core symptoms of PTSD, as well as a few others:

  • Emotional difficulties: It can be difficult to manage emotions and keep them in check. Feelings can go up and down, sometimes very quickly. The feelings can include intense anger, fear, depression, or numbness.
  • Negative self-image: You consistently don’t feel good about yourself. You feel shame, guilt, or low self-worth.
  • Relationship challenges: It can be challenging to maintain close relationships. Negative beliefs and feelings can impact connections with loved ones.

Together, these symptoms can significantly affect daily functioning, including work, relationships, and emotional stability.

Similarities between PTSD and CPTSD

PTSD and CPTSD have a lot of overlap and can be confused with one another. They both result from traumatic events. They also both have significant impacts, including the main PTSD symptoms. Similarly, both are treatable conditions with the right support. 

The overlap between PTSD and CPTSD is one reason it's important to get an accurate picture of what you're dealing with, which could be through a CPTSD test or a full clinical evaluation with a trauma-informed mental health provider. Because the main symptoms are shared, the well-researched treatments for PTSD often serve as the base for CPTSD care, too — with extra work added in to address the effects of long-term trauma on emotions, relationships, and self-image.

Trauma-focused therapies such as trauma-focused cognitive behavioral therapy, cognitive processing therapy (CPT), prolonged exposure (PE), and eye movement desensitization and reprocessing (EMDR) are all recommended treatments for PTSD by the American Psychological Association. These treatments can be helpful for CPTSD as well, but you may benefit from a phased approach that starts with stabilization before trauma processing.

Having a therapist who is well-trained and has specific experience with trauma can be a very helpful step towards healing. 

Key differences between PTSD and CPTSD

It can be challenging to identify the difference between PTSD and CPTSD. You may know trauma is affecting you but aren't sure which one applies to your experience. While these two are closely related, they have some key differences. 

Source of trauma

PTSD comes from one or very few traumatic events. CPTSD comes from ongoing traumatic events over a long period of time where there was often no chance of escape. Much of the complexity of CPTSD comes from the chronic, repeating nature of the traumatic events. 

Symptom scope

The two conditions share the main PTSD symptoms. CPTSD, however, goes beyond these symptoms and tends to have more difficulties. This is part of what leads many people to ask whether CPTSD is worse than PTSD — the emotional challenges, relationship difficulties, and consistently negative self-image can make it even harder to function in daily life.

Impact on sense of self

PTSD can negatively impact the way you feel about yourself, but with CPTSD you may experience this with even more intensity. The repeated nature of the trauma can wear down how you feel about yourself over time, often leaving behind shame, guilt, or low self-worth.

Diagnosis and recognition

You may be first diagnosed with PTSD but feel the label doesn't capture everything you're going through, especially if your trauma lasted a long time or started in childhood.

The main differences are found in the nature of the trauma that was experienced, as well as the accompanying symptoms. When you have PTSD symptoms along with ongoing struggles managing emotions, feeling okay about yourself, and connecting with others, CPTSD may be present. 

In the United States, PTSD is a mental health diagnosis that insurance companies can be billed for because it’s formally included in the mental health diagnosis book, the DSM-5-TR. CPTSD is not officially included in the DSM-5-TR, but it’s recognized by other countries and international guidelines such as the World Health Organization’s ICD-11. Many U.S. therapists still use the idea of CPTSD to understand and guide treatment, even when the official diagnosis on record is PTSD. 

Treatment for PTSD and CPTSD

Several approaches have strong research support for PTSD, and a growing body of research now addresses CPTSD. If you have PTSD or CPTSD, you can benefit from treatments like trauma-focused CBT, EMDR, prolonged exposure (PE), and cognitive processing therapy (CPT). 

  • Trauma-focused CBT helps you identify and change overly negative thoughts, which can shift your feelings and behaviors. 
  • CPT helps you notice and change the unhelpful beliefs that formed because of the specific traumatic events.
  • PE helps you face the things you’ve been avoiding related to your trauma in a safe and systematic way. Facing these fears reduces anxiety and avoidance. 
  • EMDR helps you work through past memories so they feel less distressing, while also building new, more helpful beliefs.

Treatment for CPTSD can sometimes take longer and may require a bit more care. There is often a multi-step approach that includes helping stabilize emotions before moving on to processing trauma, and eventually reconnecting with goals in life. This approach keeps you from going too deep into painful memories before you feel steady enough to handle it.

Dialectical behavior therapy (DBT) and skills training in affective and interpersonal regulation (STAIR) are commonly used skills-based approaches that may help with the common CPTSD struggles of managing emotions, building healthier relationships, and improving low self-worth. Building healthy coping skills is an important foundation for trauma work. 

Medication can also be part of a comprehensive treatment plan for PTSD. The FDA has approved certain antidepressants for PTSD, and a psychiatrist or psychiatric nurse practitioner can help evaluate whether medication might support your recovery alongside therapy.

If you or someone you know is in crisis, support is available. Call or text 988 (Suicide & Crisis Lifeline), text HOME to 741741 (Crisis Text Line), or call 911 for a mental health emergency.
