Post-Traumatic Stress Disorder (PTSD)

PTSD (Post-Traumatic Stress Disorder) is what happens when the nervous system gets "stuck" in survival mode after a traumatic event. It isn’t weakness — it’s a biological response to trauma that, in some people, doesn’t resolve on its own and needs specific treatment.

How trauma affects the brain

Intense trauma can alter brain architecture: a hyperactive amygdala (constant alarm), a reduced hippocampus (difficulty placing memories in time), and a prefrontal cortex with reduced activation (weaker emotional regulation). The result: the brain acts as though the trauma is still happening — even years later.

Symptoms of PTSD (4 clusters)

Re-experiencing

  • Involuntary flashbacks — reliving the event as if it were happening now
  • Recurrent nightmares about the trauma
  • Intense distress when reminded of or exposed to cues related to the trauma
  • Automatic physical reactions to cues (sweating, racing heart, tension)

Avoidance

  • Avoiding thoughts, feelings or conversations about the trauma
  • Avoiding places, activities or people that are reminders of the trauma

Negative changes in cognition and mood

  • Difficulty remembering aspects of the trauma
  • Persistent negative beliefs about oneself or the world ("nothing will get better", "I’m broken")
  • Persistent, distorted guilt or anger
  • Loss of interest in activities once enjoyed
  • A feeling of detachment from others
  • Inability to experience positive emotions

Hyperarousal

  • Irritability or angry outbursts
  • Self-destructive behavior
  • Hypervigilance — a constant state of alertness
  • Exaggerated startle response
  • Difficulty concentrating
  • Sleep disturbances

Treatments with evidence

EMDR (Eye Movement Desensitization and Reprocessing)

High evidence

A trauma-specific protocol: bilateral eye movements while processing traumatic memories. Recommended as a first-line treatment by major health bodies. The exact mechanism is still being studied, but efficacy in randomized trials is robust — especially for single-incident trauma.

Trauma-Focused CBT (CPT / PE)

High evidence

Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE) are the most-studied CBT approaches for PTSD. They work directly with traumatic memories and associated beliefs. Effective in 50–70% of cases, with complete remission.

Medication (SSRIs/SNRIs)

Moderate evidence

Sertraline and paroxetine are FDA-approved for PTSD. Venlafaxine (an SNRI) also has good evidence behind it. They reduce symptoms but rarely produce complete remission on their own. Most effective in combination with psychotherapy.

Somatic / Body-Based Therapy

Emerging evidence

Approaches like Somatic Experiencing (Peter Levine) and sensorimotor psychotherapy focus on the body’s responses to trauma — not just the cognitive side. Useful for complex trauma where a purely verbal approach is less accessible. Randomized evidence is still developing.

Frequently asked questions

What’s the difference between a normal reaction to trauma and PTSD?

An acute reaction to trauma (intense fear, anxiety, nightmares, numbness) in the first weeks after a traumatic event is normal and expected — the nervous system is processing something intense. PTSD is the diagnosis when those symptoms persist for more than 1 month, cause significant impairment, and fit the 4 clusters (re-experiencing, avoidance, negative cognitions, hyperarousal). Most people exposed to trauma do NOT develop PTSD — risk factors include a history of prior trauma, lack of social support, and the severity of the event.

Is PTSD permanent?

No. With proper treatment (especially EMDR or trauma-focused CBT), most people see a significant reduction in symptoms, and many reach remission. Without treatment, it can become chronic — which makes seeking specialized help important. Complex trauma (multiple traumas, especially in childhood) tends to require longer treatment and a more comprehensive approach.

Can PTSD develop years after the trauma?

Yes — delayed-onset PTSD is a recognized diagnostic category, with symptoms emerging 6 months or more after the event. It can be triggered by a subsequent event, a life transition, or when the person finally has the emotional "space" to process what had been compartmentalized. This happens especially in veterans, survivors of abuse, and people with a history of childhood trauma.

How do I support someone with PTSD?

Be a steady presence without pressuring them to talk. Don’t minimize it ("it was so long ago", "it could be worse"). Don’t force contact with triggers. Ask what actually helps — everyone’s needs differ. Encourage treatment without ultimatums. Learning about PTSD helps you understand behaviors that might otherwise seem irrational. Take care of yourself too — supporting someone with PTSD is emotionally demanding.
