PTSD: What It Is, Symptoms, and How It's Diagnosed

Post-traumatic stress disorder is not "a bad mood after stress." It is a neurobiological disorder with specific symptoms. How to recognize it.

“PTSD is only for war veterans.” This is a common myth. PTSD can develop in anyone who has experienced a traumatic event: a car accident, sexual assault, loss of a loved one, difficult childbirth, childhood abuse, natural disaster, witnessing someone else's death.

Here's what's important to know about PTSD.

1. Diagnostic Criteria for PTSD (DSM-5)

PTSD is diagnosed when all four symptom clusters are present, lasting for more than 1 month:

Cluster 1: Intrusion

  • Unwanted intrusive memories of the event
  • Nightmares about the event
  • Flashbacks (feeling as if the event is happening again)
  • Intense distress when reminded
  • Physical reactions to reminders (heart palpitations, sweating)

Cluster 2: Avoidance

  • Avoidance of thoughts and feelings associated with the event
  • Avoidance of people, places, situations that remind of the event

Cluster 3: Negative Alterations in Cognitions and Mood

  • Inability to recall details of the event
  • Persistent negative beliefs about oneself or the world
  • Self-blame
  • Persistent negative emotions (guilt, shame, fear, anger)
  • Feelings of detachment from others
  • Inability to experience positive emotions

Cluster 4: Hyperarousal

  • Irritability, angry outbursts
  • Reckless or self-destructive behavior
  • Hypervigilance
  • Exaggerated startle response
  • Concentration problems
  • Sleep disturbances

2. Physiology of PTSD

PTSD is a disorder of the nervous system "stuck" in threat mode. An overactive amygdala signals danger. A suppressed prefrontal cortex cannot "calm" it. Cortisol levels are altered. Memory architecture is changed – memories are not "completed" and intrude as if they are happening in the present.

3. PTSD vs. Acute Stress Reaction

Acute Stress Reaction (ASR): the same, but lasts less than 4 weeks. This is a normal reaction. PTSD is diagnosed only if symptoms persist for more than a month.

4. Treatment for PTSD

  • EMDR — Eye Movement Desensitization and Reprocessing therapy. Method #1 according to WHO data
  • CPT (Cognitive Processing Therapy): working with beliefs about trauma
  • PE (Prolonged Exposure): gradual "re-learning" of safety
  • Medications: SSRIs (sertraline, paroxetine — FDA-approved for PTSD)
