Introduction to PTSD (Post-Traumatic Stress Disorder): Treating Trauma and Managing Symptoms

Lesson 1 • Distinguishing PTSD from Related Conditions

Differential diagnosis between PTSD, acute stress disorder, and adjustment disorder is essential for treatment selection. Students practise distinguishing overlapping presentations.

Lesson 2 • Historical Evolution of PTSD Diagnosis

The diagnostic history from shell shock to current criteria reveals how scientific understanding has shaped treatment. This context prevents outdated clinical assumptions.

Lesson 3 • PTSD Diagnostic Criteria Overview

Current diagnostic standards for PTSD are mapped across four symptom clusters. Students gain fluency in applying criteria accurately before exploring aetiology.

Lesson 4 • Epidemiology and Prevalence of PTSD

Global and population-specific PTSD rates contextualise clinical demand. Data on high-risk groups inform triage and resource allocation decisions.

Lesson 1 • Fear Memory and Conditioning

Fear conditioning explains how neutral cues become trauma triggers. This section provides the mechanistic basis for exposure-based interventions introduced later.

Lesson 2 • Neurobiological Resilience Factors

Not all trauma exposure leads to PTSD; protective neurobiological factors moderate risk. Identifying these factors informs prevention and early intervention strategies.

Lesson 3 • Brain Structures Involved in PTSD

Amygdala hyperreactivity, hippocampal volume loss, and prefrontal hypoactivation are the core neural triad of PTSD. Students map symptoms to specific structural changes.

Lesson 1 • Validated PTSD Screening Instruments

Standardised tools provide reliable, comparable symptom data across clinical settings. Students learn to select instruments based on population, setting, and purpose.

Lesson 2 • Assessing Functional Impairment and Risk

PTSD severity is measured not only by symptom count but by functional impact and safety risk. This section integrates suicide risk assessment into the PTSD evaluation.

Lesson 3 • Formulating a Trauma Case Conceptualisation

Case conceptualisation integrates assessment data into a coherent treatment roadmap. Students produce a structured formulation linking trauma history, symptoms, and maintaining factors.

Lesson 4 • Principles of Trauma-Informed Assessment

Assessment itself can retraumatise if conducted poorly; trauma-informed principles minimise harm. Students apply these principles before using any specific instrument.

Lesson 1 • Creating Trauma-Safe Environments

Physical and relational environments either support or undermine trauma recovery. Students audit clinical spaces and communication styles for trauma-safety gaps.

Lesson 2 • Organisational Implementation of TIC

TIC must be embedded at the system level, not only in individual clinician behaviour. Students design staff training plans and policy changes to institutionalise TIC.

Lesson 3 • Core Principles of Trauma-Informed Care

The six TIC principles—safety, trustworthiness, peer support, collaboration, empowerment, and cultural sensitivity—form the framework. Students apply each principle to clinical scenarios.

Lesson 1 • Prolonged Exposure Therapy

PE uses imaginal and in-vivo exposure to extinguish conditioned fear responses. Students practise constructing exposure hierarchies and processing post-exposure emotions.

Lesson 2 • Cognitive Processing Therapy

CPT targets stuck points—distorted beliefs formed after trauma—through structured written and verbal exercises. Students learn the full 12-session protocol sequence.

Lesson 3 • Trauma-Focused CBT for Special Populations

TF-CBT adapts core CBT components for children, adolescents, and their caregivers. Students identify developmental modifications needed for younger trauma survivors.

Lesson 4 • EMDR Therapy Fundamentals

EMDR uses bilateral stimulation during trauma memory processing to reduce distress and reprocess maladaptive beliefs. Students learn the eight-phase protocol structure.

Lesson 1 • First-Line Pharmacological Treatments

SSRIs and SNRIs are the primary recommended medications for PTSD symptom reduction. Students learn their mechanisms, target symptoms, and typical response timelines.

Lesson 2 • Integrating Medication with Psychotherapy

Combined pharmacotherapy and psychotherapy often outperforms either alone for moderate-to-severe PTSD. Students coordinate care plans across prescribers and therapists.

Lesson 3 • Emerging Pharmacological Interventions

Novel agents such as MDMA-assisted therapy and ketamine are in advanced clinical trials for treatment-resistant PTSD. Students critically evaluate current evidence and ethical considerations.

Lesson 1 • PTSD and Substance Use Disorders

Substance use frequently co-occurs with PTSD as a self-medication strategy, complicating treatment sequencing. Students apply integrated dual-diagnosis treatment models.

Lesson 2 • Treatment-Resistant PTSD Strategies

When first-line treatments fail, clinicians must systematically evaluate barriers and alternative approaches. Students apply a structured decision tree for non-responding cases.

Lesson 3 • Dissociation and Trauma Treatment

Dissociative symptoms require stabilisation before trauma processing to prevent decompensation. Students apply phase-based treatment models for dissociative presentations.

Lesson 4 • PTSD with Depression and Anxiety Disorders

Comorbid depression and anxiety disorders are present in the majority of PTSD cases and worsen prognosis. Students modify treatment plans to address overlapping symptom clusters.

Lesson 1 • Transitioning from Therapy to Self-Management

Planned termination and step-down care reduce abandonment risk and consolidate treatment gains. Students structure final sessions to reinforce client autonomy and skill ownership.

Lesson 2 • Relapse Prevention Planning

Relapse prevention identifies personal triggers, early warning signs, and coping responses before treatment ends. Students co-create written relapse prevention plans with clients.

Lesson 3 • Defining and Measuring Recovery

Recovery is multidimensional, encompassing symptom reduction, functional restoration, and meaning-making. Students use validated outcome measures to track recovery progress.

Lesson 4 • Supporting Long-Term Wellness

Lifestyle factors including sleep, exercise, and social connection sustain neurobiological recovery from PTSD. Students integrate wellness planning into discharge documentation.
