Post-traumatic stress disorder (PTSD) can develop after experiencing or witnessing a frightening, dangerous or life-threatening event — such as an accident, assault, combat, disaster, or sudden loss. Most people have strong reactions after trauma, and many recover naturally over weeks. When symptoms persist for more than a month and disrupt daily life, PTSD may be the cause. Effective, well-researched treatments exist, and recovery is very possible.
The four symptom groups
- Intrusion: unwanted memories, nightmares, flashbacks, or strong distress at reminders
- Avoidance: steering clear of people, places, thoughts or conversations linked to the trauma
- Negative changes in thinking and mood: guilt, shame, feeling detached, losing interest, difficulty feeling positive emotions
- Arousal and reactivity: feeling on guard, being easily startled, irritability, poor sleep and concentration
Children may show trauma through play, clinginess, or changes in behavior. Complex PTSD can follow prolonged or repeated trauma and also affects emotion regulation, self-image and relationships.
Why some people develop PTSD
Risk depends on the nature of the trauma, previous experiences, genetics, and — importantly — the support available afterwards. Social support is one of the strongest protective factors. Developing PTSD is not a sign of weakness; it reflects how the brain's threat system adapts to danger.
Treatment
Trauma-focused psychotherapies are first-line treatments recommended by major guidelines:
- Cognitive Processing Therapy (CPT) — examines and updates beliefs shaped by trauma
- Prolonged Exposure (PE) — gradually and safely approaches memories and avoided situations
- EMDR — eye movement desensitization and reprocessing
- Trauma-focused CBT, especially for children and teens
Medications such as sertraline, paroxetine and venlafaxine can reduce symptoms. Prazosin is sometimes used for trauma-related nightmares.
Supporting someone with PTSD
- Listen without pressuring them to share details
- Learn about common reactions so they feel less "strange"
- Encourage professional help and offer practical support
- Take care of your own wellbeing, too
