Target exams

FRANZCPMRCPsychABPNMD-DNBNEET-SS

Red flags

  • Active suicidal intent, plan or recent attempt after trauma — same-day senior review, means restriction, documented safety plan
  • Ongoing interpersonal violence or unsafe discharge destination — prioritise physical safety and protection pathways before therapy homework
  • Severe dissociation, inability to care for self, or acute psychosis after trauma — escalate care intensity; do not force full exposure in crisis
  • High-risk substance intoxication/withdrawal with trauma presentation — medical stabilisation first
  • Children or dependents at risk in the household of a traumatised carer — safeguarding duty
  • Benzodiazepine as default long-term PTSD treatment — limited benefit, dependence risk, may impair extinction learning

The one-line answer

PTSD is a qualifying trauma plus four symptom clusters counted 1-1-2-2, lasting more than a month; acute stress disorder is the same territory between day three and day thirty. First-line treatment is trauma-focused psychotherapy — prolonged exposure, trauma-focused CBT, CPT or EMDR — with sertraline, paroxetine or venlafaxine XR as evidence-based drug options, prazosin as an individualised decision after a large null trial, and safety before any exposure homework.[2][16][20]

Meet the patient

A 38-year-old ambulance paramedic sits with her back to the wall and the door in view. She has not slept through a night in seven months, since a paediatric resuscitation that did not go well.[2][5]

She has stopped taking the route past that intersection. She drinks four glasses of wine to get to sleep, and she says the worst part is not the nightmare — it is the two seconds after waking when she is still there.[2][3]

Her GP has offered "a debrief with the peer support team" and citalopram 10 mg. On the ward round somebody will suggest she is "just burnt out". Both of those are examinable errors, and this topic exists to name them.[16][20]
