Post-Traumatic Stress Disorder (PTSD) is a significant topic for the UKMLA AKT, especially understanding how it's diagnosed and the specific psychological interventions recommended by NICE guidelines.

Diagnostic Criteria (ICD-11 / DSM-5)

While the DSM-5 is often cited, the UK primarily follows ICD-11 for clinical practice. PTSD typically develops following exposure to an exceptionally threatening or horrific event. The core "triad" of symptoms includes:

1. Re-experiencing: Vivid intrusive memories, flashbacks (feeling as if the event is happening again), or nightmares.
2. Avoidance: Deliberate avoidance of thoughts, memories, or external reminders (people, places, activities) associated with the trauma.
3. Hyperarousal: A persistent sense of current threat, manifesting as hypervigilance or an exaggerated startle response.

These symptoms must persist for at least one month and cause significant functional impairment.

Management: Psychological Interventions

For adults with PTSD, NICE guidelines recommend trauma-focused psychological treatments rather than routine medication as first-line therapy.

• Trauma-Focused CBT (TF-CBT): This involves identifying and challenging distorted thoughts related to the trauma, combined with "imaginal exposure" (repeatedly narrating the trauma) to help the brain process the memory properly.
• EMDR (Eye Movement Desensitization and Reprocessing): This is a unique therapy where the patient focuses on the traumatic memory while following the therapist's finger movements (bilateral stimulation). It’s thought to help the brain "unstick" the traumatic memory so it can be processed like a normal, non-threatening memory.

I'll pull up some high-yield lessons that cover these criteria and management steps in more detail for your revision.

Those lessons will give you a solid foundation on the psychiatric aspects. To help you visualize the management pathway—especially when to choose watchful waiting versus active therapy—I've put together this flowchart based on NICE guidelines.

The flowchart highlights the key decision points in PTSD management. One high-yield point for the AKT is that watchful waiting is often appropriate for the first 4 weeks after a trauma, as many people's symptoms will resolve naturally.

If symptoms persist beyond 4 weeks, that's when we move to active psychological therapy. While TF-CBT and EMDR are the heavy hitters, sometimes medication is needed—usually Venlafaxine or an SSRI like Sertraline if the patient prefers it or if psychological therapy isn't accessible or effective.

Would you like to try some practice questions on this to see how it's tested, or perhaps some flashcards to lock in those diagnostic criteria?
