What Are the Symptoms of PTSD? Complete 2026 Guide

PTSD is searched 132,000+ times per month. Here is the complete symptom profile — and why so many sufferers go undiagnosed for years.

Post-Traumatic Stress Disorder is one of the most-searched anxiety topics globally — over 132,000 monthly searches in the UK and US combined. It is also one of the most under-diagnosed, particularly in cases that don't fit the stereotype of combat or single-event trauma.

This guide covers the full symptom profile.

1. Re-experiencing symptoms

  • Vivid flashbacks (not just memories — full sensory re-living)
  • Recurring nightmares of the trauma
  • Intense distress on exposure to reminders (sounds, smells, places, people)
  • Physical reactions on exposure (sweating, racing heart, panic)
  • 2. Avoidance symptoms

  • Avoiding places, people, conversations or activities that remind you of the event
  • Inability to recall key parts of the trauma
  • Loss of interest in activities you previously enjoyed
  • Emotional numbing — difficulty feeling positive emotions
  • 3. Negative changes in mood and thought

  • Persistent negative beliefs about yourself, others, or the world
  • Distorted self-blame ("it was my fault")
  • Difficulty experiencing happiness, love, satisfaction
  • Detachment from family and friends
  • Hopelessness about the future
  • 4. Hyperarousal and reactivity

  • Hypervigilance (constantly scanning for threat)
  • Exaggerated startle response
  • Sleep disturbance
  • Irritability and angry outbursts
  • Difficulty concentrating
  • Reckless or self-destructive behaviour
  • The five-symptom rule

    For a clinical PTSD diagnosis, symptoms must persist for more than one month, cause significant distress or impairment, and not be explained by substances or another medical condition.

    Why PTSD is so often missed

    Sufferers frequently present to GPs with sleep problems, anger issues, anxiety, depression or unexplained physical symptoms — without ever connecting them to a past traumatic event. Trauma can also be cumulative (childhood adversity, prolonged stress) rather than a single incident, which fits the criteria for Complex PTSD (see our separate guide).

    Why recovery is fully possible

    PTSD is, at its core, a sensitised threat-response system that has been locked into the "on" position by trauma. The same mechanism that generates ordinary anxiety disorders generates PTSD — just calibrated by a specific historical event.

    The LAR programme addresses that sensitised response directly. For PTSD specifically, we work alongside trauma-informed clinical care where appropriate.
