Managing PTSD With Prolonged Exposure Therapy

Managing PTSD Symptoms Through Prolonged Exposure

Post-traumatic stress disorder is one of the most studied — and most treatable — psychiatric conditions. Yet many people who carry PTSD never receive evidence-based treatment, often because they fear that confronting traumatic material will make their symptoms worse rather than better. Prolonged exposure therapy is built around a different and well-supported premise: that carefully structured contact with avoided memories and situations is what allows the nervous system to update its threat predictions and finally rest.

Prolonged exposure (PE) is one of the most rigorously researched trauma treatments available, and it is a core component of comprehensive PTSD care at City Behavioral Health.

What Prolonged Exposure Is

Prolonged exposure therapy is a structured, time-limited cognitive behavioral treatment for PTSD developed by Dr. Edna Foa and colleagues. It is recommended as a first-line treatment for PTSD by the American Psychological Association, the U.S. Department of Veterans Affairs, and the International Society for Traumatic Stress Studies.

PE has two main components:

Imaginal exposure — repeatedly recounting the traumatic memory in detail during sessions, with clinical guidance, to allow emotional processing and reduce avoidance.
In vivo exposure — gradually approaching real-world situations, places, and activities that have been avoided because they trigger trauma-related distress.

A typical course is 8 to 15 weekly sessions, often around 90 minutes each, with structured between-session practice.

Why Avoidance Maintains PTSD

After trauma, avoidance is a natural and often automatic response. Steering clear of reminders, suppressing memories, refusing to talk about what happened — all of these strategies reduce distress in the short term. Over time, however, avoidance prevents the brain from updating its threat associations, which is part of why PTSD symptoms often persist for years without treatment.

Three things tend to happen when avoidance is maintained long-term:

The list of triggers expands as more situations become associated with the original trauma.
Anxiety about anxiety builds, so the experience of distress itself becomes feared.
The person’s world contracts, often unevenly, around what they no longer feel they can do.

PE works by reversing this process. With clinical support, structured contact with previously avoided material teaches the nervous system that the memory itself is not dangerous, that distress will rise and then naturally fall, and that the person can survive the discomfort without the feared catastrophe occurring.

What a Course of PE Actually Looks Like

A typical prolonged exposure protocol moves through several phases:

Psychoeducation and Treatment Planning

The therapist explains how PTSD develops and how PE works, normalizes the symptoms, and answers concerns about treatment. The plan is collaborative; nothing is forced.

Breathing and Stabilization Skills

Brief training in controlled breathing and other regulation skills gives the client tools to use when distress rises during exposures.

Building the Avoidance Hierarchy

The client and therapist construct a list of avoided situations — from mildly anxiety-provoking to severely so. This becomes the roadmap for in vivo exposure work.

Imaginal Exposure

In session, the client recounts the traumatic memory aloud, in the present tense, multiple times. The therapist supports the client through the recounting and helps process what arises afterward. Recordings of the recountings are often used for between-session practice.

In Vivo Exposure

Between sessions, the client systematically approaches real-world situations from the hierarchy — riding the subway, walking through a particular neighborhood, attending a social event — starting with manageable items and progressing as confidence builds.

Consolidation

As distress decreases and avoidance reduces, sessions focus on integrating gains, addressing residual issues, and planning for relapse prevention.

Who Prolonged Exposure Is For — and When It Isn’t

PE is well supported for adults with PTSD related to a wide range of traumatic experiences, including assault, accidents, combat, and sudden loss. It can be effective for clients with complex trauma, though clinical judgment about pacing and stabilization is especially important.

PE is generally not the first intervention when a client is acutely suicidal, in active substance dependence requiring detoxification, or in an environment where ongoing trauma is occurring. In those situations, stabilization and safety come first, and PE is introduced once the foundation supports it.

Managing PTSD Symptoms Day-to-Day During Treatment

Between sessions, several practices help clients sustain progress:

Following the practice plan. Doing the assigned imaginal recordings and in vivo exposures is what drives change.
Sleeping and eating regularly. A regulated body tolerates exposure work more readily.
Limiting alcohol and substance use. Both interfere with the memory-processing mechanisms PE relies on.
Tracking distress patterns. Noticing that distress rises and falls — rather than rises and stays — is part of how the lesson lands.

Treatment at CBH

City Behavioral Health offers prolonged exposure therapy delivered by clinicians trained in the protocol, integrated with our broader continuum of care. For clients who would benefit from concentrated work, we provide therapy intensives that compress treatment into focused weeks rather than months. For clients whose avoidance includes leaving home, in-home clinical services can be the starting point. And when PTSD coexists with emotional dysregulation or self-harm, we layer DBT-PE — a hybrid protocol that builds DBT skills before and alongside the exposure work.

A Path Forward

PTSD is not a permanent condition. With evidence-based treatment, most people experience significant reduction in symptoms — and many fully recover. Prolonged exposure asks something difficult of the people who pursue it, and it works.
