What is the recommended diagnosis and treatment approach for a patient presenting with symptoms of post-traumatic stress disorder (PTSD)?

Diagnosis and Treatment of Post-Traumatic Stress Disorder (PTSD)

For patients presenting with symptoms of PTSD, trauma-focused psychotherapy (such as prolonged exposure therapy, cognitive processing therapy, or EMDR) should be initiated as first-line treatment, with SSRIs (sertraline 50-200 mg/day or paroxetine 20-60 mg/day) recommended as pharmacological options. 1

Diagnostic Approach

Diagnostic Criteria

• PTSD diagnosis requires symptoms to persist for more than 3 months following exposure to a traumatic event 1
• Five symptom domains must be present:
  1. Exposure to actual or threatened death, serious injury, or sexual violence
  2. Intrusion symptoms (recurrent distressing memories, flashbacks, dreams)
  3. Avoidance of trauma-related stimuli
  4. Negative alterations in cognitions and mood
  5. Marked alterations in arousal and reactivity 1

Assessment Tools

• Use standardized measures such as the PTSD Checklist for DSM-5 (PCL-5) to track symptoms weekly 1
• The PCL-5 can be divided into subscores corresponding to the three main symptom clusters: reexperiencing, avoidance, and hyperarousal 2

Differential Diagnosis

• Consider Complex PTSD (recognized in ICD but not in DSM-5) 1
• Rule out adjustment disorder, acute stress disorder, major depressive disorder, anxiety disorders, and substance-induced disorders 1
• For symptoms present less than 30 days after trauma, consider posttraumatic stress syndrome (PTSS) 3

Treatment Approach

First-Line Treatments

1. Trauma-Focused Psychotherapy

   • Strongly recommended by both APA and VA/DoD guidelines 4
   • Effective options include:
     • Prolonged Exposure (PE) therapy
     • Cognitive Processing Therapy (CPT)
     • Trauma-focused Cognitive Behavioral Therapy (CBT)
     • Eye Movement Desensitization and Reprocessing (EMDR) 1, 4
   • Evidence strongly supports trauma-focused treatments even without prior stabilization phase 5, 1

2. Pharmacotherapy

   • First-line medications:
     • Sertraline (50-200 mg/day): Start at 25 mg/day for first week, then titrate based on response 1, 6
     • Paroxetine (20-60 mg/day) 1, 7
     • These SSRIs have demonstrated efficacy in multiple controlled trials 1, 8
   • Continue effective medication for at least 6-12 months to decrease relapse rates 1

Treatment Algorithm

1. Initial Approach:

   • Begin trauma-focused psychotherapy as first-line treatment
   • Consider adding SSRI (sertraline or paroxetine) concurrently, especially with severe symptoms or comorbid depression

2. If inadequate response after 8-12 weeks:

   • Switch to alternative trauma-focused therapy approach
   • Adjust medication dose if using pharmacotherapy
   • Consider combination therapy if using only one modality

3. For residual symptoms:

   • Consider adjunctive treatments for specific symptoms (e.g., prazosin for nightmares) 8
   • Evaluate for comorbid conditions that may require targeted treatment

Special Considerations

Sleep Disturbances

• Sleep problems are common in PTSD due to hyperarousal or nightmares
• Consider screening for obstructive sleep apnea 8
• Prazosin may be effective for PTSD-related sleep disturbance 8

Medications to Avoid

• Benzodiazepines are not recommended for PTSD treatment as they may worsen outcomes 1

Comorbidities

• Psychiatric comorbidities, particularly mood disorders and substance use, are common in PTSD 8
• Treat comorbid conditions concurrently for best outcomes

Long-Term Management

• Monitor progress using standardized PTSD measures (PCL-5) 1
• Continue effective treatment for at least 6-12 months 1
• Periodically re-evaluate the need for ongoing treatment 6, 7

Treatment Efficacy

• Trauma-focused psychotherapies have demonstrated stronger treatment effects compared to pharmacological interventions 9
• SSRIs have shown modest but significant effects in reducing PTSD symptoms 9
• In clinical trials, 53-85% of participants using SSRIs were classified as treatment responders 1

Remember that early recognition and intervention may help reduce the severity and chronicity of PTSD symptoms, potentially preventing progression to chronic PTSD 3.
