Post-Traumatic Stress Disorder: Understanding Trauma and Recovery

Post-Traumatic Stress Disorder (PTSD) is a psychiatric condition that can develop following exposure to a traumatic event — an event involving actual or threatened death, serious injury, or sexual violence. PTSD can also develop through indirect exposure, such as learning that a close family member or friend experienced a traumatic event, or through repeated exposure to details of traumatic events (as may occur in first responders and journalists).

Not everyone who experiences trauma develops PTSD. Epidemiological data suggest that approximately 10 to 15 percent of individuals exposed to trauma go on to develop PTSD, though rates are higher following certain types of trauma (combat, sexual assault, childhood abuse) and in populations with additional risk factors. In Nepal, PTSD prevalence is elevated in populations affected by the 2015 earthquake, political conflict, and gender-based violence.

Dr. Ruja Shrestha — consultant psychiatrist & cbt therapist at Kathmandu Neurology Clinic & Cognitive Center provides evidence-based evaluation for post-traumatic stress disorder.

The DSM-5 organizes PTSD symptoms into four clusters. Intrusion symptoms include recurrent, involuntary, and intrusive memories of the traumatic event, distressing dreams related to the event, dissociative reactions (flashbacks), and intense psychological or physiological distress when exposed to reminders of the trauma. Avoidance symptoms involve persistent effortful avoidance of thoughts, feelings, or external reminders (people, places, conversations, activities, objects) associated with the traumatic event. Negative alterations in cognitions and mood include persistent negative beliefs about oneself or the world, distorted blame of self or others, persistent negative emotional state, diminished interest in activities, feelings of detachment, and inability to experience positive emotions. Arousal and reactivity symptoms include irritability, reckless or self-destructive behavior, hypervigilance, exaggerated startle response, difficulty concentrating, and sleep disturbance.

Symptoms must persist for more than one month and cause clinically significant distress or functional impairment. Acute PTSD is diagnosed when symptoms last less than three months; chronic PTSD when they persist for three months or more.

The neurobiology of PTSD involves dysregulation of the fear response system. Research has shown that PTSD is associated with hyperactivation of the amygdala (the brain's threat detection center), reduced activity in the prefrontal cortex (involved in emotion regulation and extinction of fear responses), and hippocampal volume reduction (affecting contextual memory and the ability to distinguish safe from dangerous contexts). These neurobiological changes explain why individuals with PTSD experience persistent threat responses even in safe environments.

Evidence-based treatments for PTSD are well-established. Trauma-focused psychotherapies are considered first-line treatments. Prolonged Exposure (PE) therapy involves systematic confrontation with trauma-related memories and situations that have been avoided, promoting emotional processing and habituation. Cognitive Processing Therapy (CPT) focuses on identifying and modifying maladaptive beliefs related to the trauma. Eye Movement Desensitization and Reprocessing (EMDR) involves processing traumatic memories while engaging in bilateral stimulation (typically eye movements).

Pharmacotherapy plays an important role in PTSD management. SSRIs (sertraline and paroxetine are FDA-approved for PTSD) and SNRIs are first-line medication options. Prazosin may be used for trauma-related nightmares, though recent research has produced mixed findings. Benzodiazepines are generally not recommended for PTSD as they may interfere with trauma processing and carry risks of dependence.

In Nepal, many individuals exposed to trauma — including survivors of the 2015 earthquake, former child soldiers, and survivors of gender-based violence — lack access to evidence-based PTSD treatment. Cultural and religious frameworks may influence how trauma is understood and expressed. Community-based psychosocial support, culturally adapted interventions, and integration of mental health services into primary care are important strategies for addressing PTSD in resource-limited settings.

Recovery from PTSD is possible. Many individuals experience significant symptom reduction with appropriate treatment, and some achieve full remission. Early intervention, strong social support, and access to evidence-based treatment are associated with better outcomes. While some individuals may continue to experience some symptoms, effective management strategies can help restore functioning and quality of life.

**Frequently Asked Questions**

Q: Can PTSD develop long after a traumatic event? A: Yes. PTSD symptoms can emerge weeks, months, or even years after the traumatic event. Delayed-onset PTSD, where symptoms first appear at least six months after the event, is a recognized pattern, particularly when additional stressors or reminders trigger the onset.

Q: Is PTSD the same as normal stress after a traumatic event? A: It is normal to experience some distress after a traumatic event. PTSD is diagnosed when symptoms are persistent (lasting more than one month), severe, and cause significant impairment in daily functioning. Most people recover naturally with time and social support.

Q: Can children develop PTSD? A: Yes. Children can develop PTSD following traumatic experiences. Symptoms in children may differ from adults and can include repetitive play involving themes of the trauma, frightening dreams, and regressive behavior. Age-appropriate interventions are available and effective.
