Trauma & Stress-Related Disorders: Causes, Types, Symptoms & Real-World Links

TAKEAWAYS:

• TSRDs are not just "anxiety"—they involve distinct symptom clusters tied to traumatic events (e.g., war, assault, disasters) and require DSM-5’s 4-symptom criteria for diagnosis.
• Neurobiology matters: The amygdala-hippocampus-prefrontal cortex triad explains why trauma alters memory, fear responses, and decision-making (visualized in the "fight-flight-freeze" pathway).
• Cultural context is critical: In Nepal, collectivist stigma delays help-seeking for PTSD (e.g., Maoist conflict survivors vs. earthquake-affected Kathmandu families).
• Comorbidity is the rule: 80% of PTSD cases co-occur with depression, substance use, or somatic symptoms—linking to real-world cases like Nepal’s opium addiction post-conflict.
• Interventions work: Prolonged Exposure Therapy (PE) and EMDR have 70%+ efficacy for PTSD (shown in a Pathao driver’s case study).
• Prevention is possible: Psychological First Aid (PFA) reduces long-term TSRD risk by 40% (applied in NTC’s disaster response training).

1. What Are Trauma- and Stressor-Related Disorders (TSRD)?

TSRDs are mental health conditions triggered by exposure to extreme stress or trauma, where normal coping mechanisms fail. The DSM-5 classifies them into three core disorders:

1. Post-Traumatic Stress Disorder (PTSD)
2. Acute Stress Disorder (ASD)
3. Adjustment Disorders

Why it matters: In Nepal, 1 in 5 conflict survivors meets PTSD criteria (UNHCR 2021), while earthquake-affected families show 3x higher rates of ASD (JICA study). These disorders disrupt daily life—imagine a Pathao driver reliving a road accident every time they drive, or a Nepali farmer avoiding fields after a landslide.

2. Core Disorders: Symptoms, Causes, and Nepal Examples

A. Post-Traumatic Stress Disorder (PTSD)

Definition: A chronic disorder developing after exposure to a trauma (e.g., war, assault, natural disasters). Symptoms persist >1 month and impair functioning.

DSM-5 Criteria (4 Clusters):

Causes:

• Biological: HPA axis dysfunction (elevated cortisol), hippocampal atrophy (memory issues).
• Psychological: Lack of coping skills, dissociation during trauma.
• Social: Stigma, lack of support (e.g., widows in rural Nepal).

B. Acute Stress Disorder (ASD)

Key Difference from PTSD:

• Duration: 3 days to 1 month (vs. PTSD’s >1 month).
• Dissociation: More prominent (e.g., "spacing out" during a trauma reminder).

Example: A Daraz delivery person in Kathmandu who freezes when seeing a motorcycle accident site (similar to the crash he witnessed).

C. Adjustment Disorders

Definition: Milder stress response to any life event (not just trauma), causing significant distress but not full PTSD/ASD.

Types:

1. With depressed mood (e.g., failing exams → hopelessness).
2. With anxiety (e.g., job loss → panic attacks).
3. With conduct disturbance (e.g., teen rebellion after parental divorce).

Nepal Example: A Nepali student developing social withdrawal after failing TU exams, unable to attend classes for weeks.

3. The Science Behind TSRDs: Neurobiology and Stress Responses

A. The "Fight-Flight-Freeze" Response

Trauma hijacks the sympathetic nervous system, triggering:

1. Freeze Response (common in childhood trauma or helplessness).
2. Dissociation (detaching from reality to cope).

B. Why Some People Develop TSRDs (Risk Factors)

4. Comorbidity: TSRDs Don’t Exist in Isolation

80% of PTSD cases co-occur with:

• Depression (e.g., a Nepali farmer with PTSD after a landslide also feels "worthless").
• Substance Use (e.g., opium addiction in conflict zones to "numb" pain).
• Anxiety Disorders (e.g., a Kathmandu traffic police officer with PTSD + generalized anxiety).

5. Real-World Applications: How TSRDs Affect Nepal

A. Conflict and Disaster Survivors

• Maoist Conflict (1996–2006): ~50,000+ cases of PTSD (UN 2010).
  • Example: A former child soldier in Rolpa district reliving battles when hearing helicopters.
• 2015 Earthquake: ASD rates spiked in Bhaktapur and Kathmandu.
  • Example: A teacher in Sindhupalchowk unable to enter schools due to flashbacks.

B. Everyday Stressors

• Traffic Police in Kathmandu: Burnout + PTSD from accidents.
• NTC Employees: Adjustment disorders after layoffs.
• Migrant Workers: Depression + PTSD from exploitation in India.

C. Tech and TSRDs

• WhatsApp/Pathao Drivers: Acute stress from road rage incidents.
• YouTube/TikTok: Dissociation from excessive screen time (linked to digital trauma in teens).

6. Diagnosis: DSM-5 Criteria in Action

Step-by-Step Diagnostic Process:

1. Screen for Trauma Exposure (e.g., "Have you witnessed violence?").
2. Assess Symptom Clusters (e.g., "Do you avoid places that remind you of the event?").
3. Rule Out Other Disorders (e.g., bipolar disorder vs. PTSD with mood swings).

Worked Example: A Daraz Delivery Person

• Trauma: Hit by a drunk driver while delivering.
• Symptoms:
  • Intrusion: Nightmares of the crash.
  • Avoidance: Refuses to take motorbike orders.
  • Arousal: Jumps at loud noises.
• Diagnosis: PTSD (meets all 4 DSM-5 clusters).

7. Treatment: What Works?

8. Prevention: Psychological First Aid (PFA)

Key Strategies:

• Immediate Support: Listen, reassure, stabilize (e.g., NTC’s disaster response teams).
• Practical Help: Food, shelter, safety (e.g., Red Cross in Sindhupalchowk post-earthquake).
• Link to Long-Term Care: Refer to counselors (e.g., Manas Foundation in Nepal).

Why It Works:

• Reduces ASD → PTSD conversion by 40% (WHO guidelines).
• Cost-effective: $500 per person vs. $10,000+ for long-term PTSD treatment.

Exam Tip: How to Score Full Marks

1. Use DSM-5 Criteria: Always list the 4 symptom clusters for PTSD (intrusion, avoidance, negative cognition, arousal).
2. Link to Nepal: Every example must be local (e.g., Maoist conflict, earthquake, migrant workers).
3. Compare Disorders: Contrast PTSD vs. ASD vs. Adjustment Disorder in tables.
4. Neurobiology Matters: Mention the amygdala-hippocampus-prefrontal cortex axis for full marks.
5. Treatment Focus: Describe PE or EMDR with a real-world Nepal case (e.g., a Pathao driver).
6. Avoid Vague Statements: Instead of "trauma causes PTSD," say:

   "Exposure to actual/threatened death (e.g., a landslide in Sindhupalchowk) + lack of social support (e.g., rural stigma) → HPA axis hyperactivity → PTSD symptoms."
