Excerpt from the Book
Introduction
Whether it is war-traumatized soldiers, refugees, victims of sexual assault or victims of catastrophic life events, the psychiatric consequence of the posttraumatic stress leading to a mental disorder if left untreated can be debilitating. The prevalence of posttraumatic stress disorder (PTSD) in countries that have suffered war and political conflicts such as Northern Ireland (Muldoon et.al.2007, p.146), Uganda (Mugisha et.al, 2015,p.2) and Palestine (Canetti et.al.2010, p.219) ranged between twenty to seventy percent. Analysis of epidemiological surveys by the World Mental Health, between 2012 until 2015 for non-war related traumatic event reported 54% of lifetime prevalence in Europe, 56.1% in Italy and 60.6% in Northern Ireland (Atwoli et al., 2015, p.302). Given the potential economic and psychosocial impact of PTSD, efforts to identify biomarkers of risk, disease and treatment of PTSD is of significant public health importance (McCrone et al., 2003,p.519). The psychiatric codification of PTSD has made possible for patients to access medical care and treatment. Likewise, mental health professionals were able to predict reliably, distinguish and diagnose trauma-associated disorder from other major mental illness (APA, 2013). However, the issue of whether PTSD owes its existence to environmental context, individual differences and learning or whether it is entirely neurobiological determined has been debated fiercely (Charney et. al., 2002, p.32). Findings from the neuroimaging and translational research provide evidence that supports the neurobiological theories of etiology but yet to find a specific biomarker for PTSD (Zoladz & Diamond, 2013,p. 890). In fact, research outcome strongly suggest PTSD is a result of interaction between biological, individual predisposition and environmental context.
Summary of Chapters
Introduction: Provides an overview of the prevalence and public health significance of PTSD while introducing the debate between neurobiological and environmental causes.
History: Outlines the historical evolution of trauma symptoms and their formal categorization, culminating in the DSM-III classification.
Diagnostic Criteria: Discusses the standardization of PTSD diagnosis through systems like DSM-5 and ICD-10 to facilitate clinical practice.
The biological hypotheses of PTSD: Explores the role of the HPA axis and neurobiological processes in stress responses and disorder maintenance.
Animal model of PTSD: Examines how laboratory animal models contribute to understanding fear circuits, despite inherent limitations compared to human experience.
Gender Differences: Analyzes how physiological differences in stress circuitry lead to variations in emotional response between men and women.
Age: Highlights developmental differences in emotional memory consolidation and the potential for early-age intervention.
Cognitive Reserve: Explores how cognitive ability influences resilience and responsiveness to therapeutic interventions.
Genetic Factors.: Investigates the heritability of PTSD and the epigenetic markers associated with susceptibility and resistance.
Sleep: Discusses the impact of REM-sleep deprivation on memory consolidation and fear extinction.
PTSD treatment: Provides a comprehensive overview of management strategies, separated into pharmacology and psychosocial therapies.
Conclusion: Summarizes the current state of PTSD research, acknowledging the ongoing debate over diagnostic criteria while affirming the clinical utility of the concept.

Frequently Asked Questions
What is the primary focus of this work?
This work focuses on the diagnostic evolution, etiological debates, and treatment modalities associated with Posttraumatic Stress Disorder (PTSD).
What are the central themes discussed?
The central themes include the biological versus environmental causes of PTSD, the validity of diagnostic systems, and the efficacy of both pharmacological and psychosocial treatments.
What is the primary research question?
The research investigates whether PTSD is strictly a neurobiological disorder or if it is shaped significantly by individual differences and environmental contexts.
Which scientific methods are utilized?
The work employs a review of epidemiological surveys, neuroimaging findings, animal model studies, and meta-analyses of clinical treatment trials.
What is covered in the main body of the text?
The main body covers historical developments, biological hypotheses, the impact of demographic and genetic factors, and a detailed review of therapeutic interventions like PE, CBT, and EMDR.
Which keywords characterize this work?
Key terms include PTSD, neurobiology, Cognitive Behavioral Therapy (CBT), pharmacological treatment, resilience, and diagnostic criteria.
How does the author evaluate the use of animal models?
The author notes that while animal models provide valuable insights into fear circuits and neural plasticity, they are limited by their inability to capture complex human verbal cognition and the delayed onset of symptoms seen in war veterans.
Why is pharmacotherapy considered a second-line treatment?
It is considered second-line because there are currently no PTSD-specific drugs; existing medications are primarily designed to treat symptoms of other mental illnesses and often present inconsistent efficacy and significant side effects.
What is the role of Cognitive Reserve in PTSD?
Higher cognitive reserve, often indicated by higher IQ, is associated with greater resilience to developing PTSD and better responses to cognitive and exposure-based therapies.
