Understanding PTSD

Post-Traumatic Stress Disorder (PTSD) is a mental health condition triggered by experiencing or witnessing a terrifying event.

In one sentence: PTSD develops when the brain's normal trauma processing becomes stuck, causing persistent re-experiencing, avoidance, and hyperarousal long after the danger has passed.

Introduction

Post-Traumatic Stress Disorder (PTSD) is a mental health condition triggered by experiencing or witnessing a terrifying event. While it's normal to have difficulty coping after trauma, PTSD involves symptoms that persist and interfere with daily life.

Key Points

  • Not everyone develops PTSD: Most trauma survivors recover naturally; PTSD occurs in about 6-8% of people who experience trauma.
  • Many types of trauma can cause PTSD: Combat, assault, accidents, disasters, childhood abuse, and other traumatic events can all lead to PTSD.
  • Symptoms fall into four clusters: Re-experiencing, avoidance, negative changes in thoughts/mood, and hyperarousal.
  • Effective treatments exist: Trauma-focused therapies like CPT, PE, and EMDR are highly effective.
  • Recovery is possible: With appropriate treatment, most people with PTSD experience significant improvement.

Symptom Clusters

Re-experiencing: Intrusive memories, flashbacks (feeling like the trauma is happening again), nightmares, and intense distress when reminded of the trauma.

Avoidance: Avoiding thoughts, feelings, people, places, or activities that remind you of the trauma.

Negative changes in thoughts and mood: Negative beliefs about self or world, distorted guilt or blame, persistent negative emotions, detachment from others, inability to feel positive emotions.

Hyperarousal: Being easily startled, feeling tense or "on edge," difficulty sleeping, irritability, difficulty concentrating, hypervigilance.

What Happens in the Brain

Trauma can alter brain function in several ways:

  • Amygdala: Becomes hyperactive, triggering fear responses even when safe
  • Hippocampus: May shrink; has difficulty processing memories as "past"
  • Prefrontal cortex: Less able to regulate the amygdala's fear responses
  • Stress hormones: Remain elevated, keeping the body in a state of alert

This explains why traumatic memories feel so present and why the body continues reacting as if the danger is current.

Evidence-Based Treatments

Prolonged Exposure (PE): Gradually approaching trauma-related memories and situations to reduce their power.

Cognitive Processing Therapy (CPT): Examining and modifying unhelpful beliefs about the trauma.

EMDR: Processing traumatic memories while engaging in bilateral stimulation (like eye movements).

Medications: SSRIs can help manage symptoms, though therapy is typically first-line treatment.

Paths to Healing

Recovery involves learning that the trauma is in the past, processing the experience, rebuilding a sense of safety, and reconnecting with life. This takes time and often professional support, but healing is possible. Many survivors report post-traumatic growth—finding new meaning, strength, or priorities after trauma.
