How prolonged exposure therapy works for PTSD and more

Living with post-traumatic stress disorder (PTSD) can feel like being trapped in an endless loop of painful memories, fear, and emotional turmoil. But there is hope — and one of the most effective treatments available today is prolonged exposure therapy (PE therapy). This therapeutic method helps individuals confront their trauma in a safe and structured environment, allowing them to regain control over their thoughts and emotions.

In this in-depth guide, we’ll explore how prolonged exposure therapy works, what it involves, who it’s for, and the proven results it delivers. Whether you’re seeking treatment for yourself or researching to help a loved one, this article will provide you with everything you need to know.

What Is Prolonged Exposure Therapy for PTSD?

Prolonged exposure therapy is a specialized form of cognitive behavioral therapy (CBT) designed to help individuals process and overcome trauma-related fears. By safely and repeatedly facing trauma triggers in therapy sessions, individuals gradually reduce their emotional response to them. This method aims to desensitize the person to painful memories and break the cycle of avoidance and fear.

Rather than encouraging someone to “forget” or suppress traumatic memories, prolonged exposure therapy helps them confront those memories until they become less distressing. With time and consistency, individuals often report significant reductions in anxiety, fear, and avoidance behaviors.

This therapy is typically conducted over 8 to 16 sessions, with each session lasting about an hour. It’s supported by decades of research and has shown excellent results in clinical trials — especially in cases of PTSD stemming from combat, sexual assault, accidents, or other life-threatening events.

Understanding PTSD: What It Is and How It Affects You

Post-traumatic stress disorder is a serious mental health condition triggered by experiencing or witnessing a traumatic event. While anyone can develop PTSD, it’s most common among veterans, survivors of assault or accidents, and individuals exposed to long-term emotional or physical abuse.

The U.S. Department of Veterans Affairs (VA) categorizes PTSD symptoms into four key areas:

1. Intrusive Symptoms

These include frequent and distressing memories, nightmares, or flashbacks that make you feel like you’re reliving the trauma. These symptoms often appear out of the blue and can be emotionally overwhelming.

2. Avoidance Behaviors

People with PTSD tend to avoid places, activities, or even thoughts that remind them of the trauma. For example, someone in a car accident might avoid driving, while someone attacked in public may stay away from crowds.

3. Negative Changes in Mood and Thinking

PTSD often causes a persistent negative outlook, feelings of guilt or shame, memory gaps about the event, or a sense of emotional numbness. This can make it hard to connect with others or find joy in activities.

4. Hyperarousal and Reactivity

Many PTSD sufferers feel constantly on edge — easily startled, quick to anger, or unable to sleep. This heightened state of alertness, known as hyperarousal, can interfere with daily life and relationships.

These symptoms can appear shortly after the trauma or sometimes months or even years later. To be diagnosed with PTSD, an individual must experience symptoms from each of these categories for at least one month.

What Happens During Prolonged Exposure Therapy?

Prolonged exposure therapy doesn’t dive straight into traumatic memories. It starts gradually, with the therapist building trust and helping the patient feel safe and supported. Over time, patients begin to confront the traumatic memories and situations they’ve been avoiding.

The Therapy Process Generally Includes:

1. Initial Sessions: Education and Breathing Techniques
   • The therapist explains how trauma affects the brain and introduces controlled breathing to help manage anxiety.
   • The patient shares personal history and trauma-related experiences.
2. Developing a Fear Hierarchy
   • Therapist and patient identify triggers and rank them from least to most distressing.
   • This serves as a roadmap for gradual exposure.
3. Engaging in Exposure Exercises
   • These begin once the patient is ready, using various methods tailored to their experience.

Let’s take a closer look at the types of exposure involved:

Types of Exposure in PE Therapy

1. Imaginal Exposure

Imaginal exposure involves reliving the traumatic event in the mind, guided by the therapist. The patient talks about the event in detail, using present-tense language to make the memory feel immediate. Sessions are recorded so patients can listen again between visits to reinforce desensitization.

This method helps the individual reprocess painful memories in a controlled environment, gradually reducing their emotional charge.

2. In Vivo Exposure

In this type, patients are encouraged to face real-life situations that remind them of the trauma — but in a slow, manageable way. For instance, someone fearful of crowded places may start by spending short periods in a park and slowly progress to a grocery store or concert.

The idea is to retrain the brain by repeatedly showing it that these situations are no longer dangerous.

3. Interoceptive Exposure

This technique focuses on internal bodily sensations — like heart rate, temperature, or dizziness — that often trigger anxiety or panic. By intentionally inducing these sensations (through controlled exercises), patients become more tolerant and less fearful of them.

This is especially helpful for those whose trauma involves physical sensations (e.g., survivors of medical trauma, panic attacks, or abuse).

Benefits of Prolonged Exposure Therapy for PTSD

When it comes to treating PTSD, prolonged exposure therapy is widely regarded as one of the most effective options. Its strength lies in helping individuals break the powerful connection between trauma and fear, enabling them to reclaim their lives with greater control and confidence.

Here’s how PE therapy helps:

1. Reduces Trauma-Related Distress

Facing the source of trauma repeatedly in a safe setting leads to a process known as habituation — over time, the intensity of fear and distress associated with the memory begins to fade. Patients report fewer nightmares, flashbacks, and anxiety attacks as therapy progresses.

2. Promotes Emotional Processing

Instead of avoiding trauma, PE therapy allows people to acknowledge and process their emotions. This often brings clarity and closure, and allows individuals to reframe the event in a healthier, more empowering way.

3. Improves Overall Mental Health

Even though PE therapy focuses on PTSD, many patients experience improvements in related mental health conditions, such as depression or anxiety. Research has shown that depression symptoms often decrease significantly after successful PE therapy, even when they weren’t the primary target.

4. Encourages Empowerment and Confidence

Avoidance often controls the life of someone with PTSD. As patients confront fears and successfully manage triggers, they gain a renewed sense of confidence. They begin participating in activities they once avoided — such as driving, socializing, or working — and enjoy a higher quality of life.

5. Backed by Research and Real-World Results

• A 2018 study found PE therapy effective for individuals with chronic PTSD, even after multiple failed treatments.
• Veterans with both combat and non-combat trauma saw significant improvements after completing PE programs.
• Trauma-focused psychotherapies like PE therapy are strongly recommended by organizations such as the VA and APA for PTSD treatment.

What Are the Risks of Prolonged Exposure Therapy?

Like any mental health treatment, PE therapy isn’t without its challenges. However, the risks are generally low and manageable when guided by a trained professional.

Potential Side Effects Include:

• Increased emotional discomfort: Confronting trauma can bring up painful feelings, especially in the early stages of therapy.
• Temporary spike in PTSD symptoms: Some individuals may experience a short-term increase in symptoms before improvements kick in.
• Risk of retraumatization: In rare cases, revisiting traumatic memories without adequate support could cause distress, especially if therapy is rushed or the individual isn’t ready.

How Therapists Manage Risk

Licensed therapists trained in PE therapy follow structured protocols to reduce risk. They monitor emotional responses closely, adjust pacing, and provide tools (like breathing exercises and grounding techniques) to help patients manage discomfort. Therapy always takes place in a safe, controlled setting, with the patient in charge of the process.

Modern Enhancements

With technology advancing, PE therapy is becoming more accessible. Online therapy platforms and telehealth sessions have made it easier for people in remote or underserved areas to receive high-quality care without compromising safety or effectiveness.

Success Rates of Prolonged Exposure Therapy

Prolonged exposure therapy isn’t just theory — it’s backed by impressive success rates and clinical outcomes.

Key Findings from Recent Research:

• 2022 study: Reported response rates between 65% and 80%, showing a significant reduction in PTSD symptoms after completing PE therapy.
• 2024 analysis: Among individuals who had tried multiple therapies previously, 46–60% achieved full symptom recovery, and 44–48% no longer met the criteria for PTSD after a combined treatment plan that included PE therapy.

These numbers underscore how powerful PE therapy can be, even in complex or treatment-resistant cases. It’s especially encouraging for those who may feel hopeless after failed attempts with medication or other therapeutic approaches.

FAQs

1. Who is a good candidate for prolonged exposure therapy?

Anyone diagnosed with PTSD — especially those who avoid reminders of trauma — may benefit from PE therapy. It’s especially effective for veterans, assault survivors, accident victims, and individuals with chronic PTSD.

2. Is prolonged exposure therapy the same as EMDR?

No. While both treat PTSD, PE therapy uses repeated exposure and cognitive processing, whereas Eye Movement Desensitization and Reprocessing (EMDR) involves guided eye movements to process traumatic memories differently.

3. How long does prolonged exposure therapy take to work?

Most individuals begin noticing improvements by the 6th to 8th session, with full treatment usually lasting 8 to 16 weeks. The pace may vary based on individual needs.

4. Can PE therapy be done online?

Yes. Many therapists offer PE therapy through telehealth platforms, and studies have shown that virtual sessions can be just as effective as in-person visits for many patients.

5. Is it normal to feel worse before feeling better in therapy?

Yes. Confronting trauma can initially increase distress. However, this is a sign that the therapy is working, and with proper support, most patients experience substantial relief over time.
