PTSD

The central feature of Posttraumatic Stress Disorder (PTSD) is the development of a wide array of symptoms following exposure to a traumatic event.

These symptoms include:

• Fear-Based Reexperiencing (Reliving the trauma through flashbacks or nightmares)
• Emotional and Behavioral Disturbances (Mood swings and avoiding reminders of the trauma)
• Anhedonic or Dysphoric Mood States (Loss of interest in activities and feeling sad)
• Negative Cognitions (Negative thoughts about oneself or others)
• Arousal (Being easily startled and having trouble sleeping)
• Reactive-Externalizing Symptoms (Acting out with anger or risky behavior)
• Dissociative Phenomena (Feeling disconnected from oneself or surroundings)

Traumatic events that can lead to PTSD encompass war, physical or sexual assault, kidnapping, terrorist attacks, torture, natural disasters, and severe accidents. Affected individuals often attempt to avoid thoughts, feelings, or situations associated with the traumatic event. Additionally, they may experience negative alterations in cognition and mood, such as amnesia, exaggerated negative expectations, persistent erroneous beliefs, persistent negative mood states, diminished interest in activities, feelings of detachment, and an inability to experience positive emotions.

Behavioral symptoms include irritability, aggression, reckless or self-destructive behavior, heightened threat sensitivity, exaggerated startle response, concentration difficulties, sleep disturbances, and dissociative symptoms like depersonalization and derealization. 

Indicators Supporting Diagnostic Assessment

PTSD may manifest through a variety of symptoms and associated features. One of the more alarming signs, however, is developmental regression (loss of previously acquired skills). Developmental regression is mostly encountered in young children, where a child loses a previously acquired language skill. Another detrimental symptom that may occur is auditory pseudo-hallucinations: hearing one’s thoughts spoken in different voices, often accompanied by paranoia. Such symptoms occur most often in individuals who have experienced severe trauma, such as childhood abuse, for an extended period. As a consequence of these symptoms, individuals often face challenges maintaining stable relationships and managing their emotions.

Prevalence

The occurrence of PTSD depends significantly on geographic location and the population that is observed. In the United States, for instance, the risk of developing PTSD by the age of 75 is 8.7%. However, in other parts of the world, the prevalence rates are generally lower and range between 0.5% and 1.0%. 

An individual’s occupation also significantly influences exposure to traumatic events and can therefore increase the risk of PTSD, with higher rates observed in veterans, police officers, firefighters, and emergency personnel. 

Another factor in the prevalence of PTSD seems to be age and cultural background. Children and adolescents have shown lower prevalence rates, mostly due to previously insufficient developmental criteria. When considering cultural and demographic factors, in the United States, higher rates of PTSD were observed among Latinos, African Americans, and American Indians compared to non-Latino whites and Asian Americans.

Development and Progression of PTSD

The development of PTSD is not restrained by age and can manifest at any age after the first year of life, most often arising within the first three months after a traumatic event. However, due to a phenomenon called “delayed exposure“, it is possible that the criteria for a full diagnosis are not met until months or even years after the exposure to a traumatic event.

The exact symptoms of PTSD may also fluctuate with time, with about half of the individuals experiencing recovery within three months, while others may inhibit symptoms for years or even decades. Reminders of the original trauma, ongoing stress, and new traumatic events may be the possible causes of a fluctuation in the intensity and duration of symptoms. Other factors, such as deteriorating physical and cognitive health and isolation, might influence symptoms as well.

Risk Factors Influencing PTSD Vulnerability

Risk factors are most often divided into three categories:

Pretraumatic factors (conditions or characteristics present before a traumatic event)

Temperamental factors include aspects such as emotional problems by the age of 6, including externalizing or anxiety issues, as well as prior mental disorders like panic disorder, depressive disorder, PTSD itself, or obsessive-compulsive disorder (OCD). Environmental factors include socioeconomic status, education levels, exposure to prior trauma, childhood adversities such as economic deprivation or parental separation, cultural coping strategies, intelligence levels, minority racial/ethnic status, and family psychiatric history.

Lastly, genetic, and physiological factors include gender, with females at higher risk, and age at the time of trauma exposure, with younger individuals at increased risk. Certain genetic predispositions may either confer protection against or elevate the risk of developing PTSD following trauma exposure.

Peritraumatic factors (conditions or characteristics during a traumatic event)

Environmental factors play a crucial role in the development of PTSD. These factors include the severity and “dose” of trauma, with a higher magnitude of trauma increasing the likelihood of PTSD. Perceived life threats, personal injury, and interpersonal violence, especially when perpetrated by a caregiver or involving a witnessed threat to a caregiver in children, are also influential factors. For military personnel, being a perpetrator, witnessing violence, or committing violent acts can contribute to the development of PTSD.

Posttraumatic factors (conditions or characteristics after a traumatic event)

Temperamental factors such as negative appraisals, inappropriate coping strategies, and the development of acute stress disorders can influence the development of PTSD. Environmental factors include subsequent exposure to repeated upsetting reminders, subsequent adverse life events, and financial or other trauma-related losses.

Cultural Factors in PTSD Diagnosis and Expression

Cultural nuances play a significant role in shaping the risk and occurrence of PTSD across different cultural groups. The onset and severity of PTSD can be influenced by various factors rooted in cultural experiences. For example, in some cultures, exposure to certain types of traumas, such as acts of genocide, may be more common. 

Another significant factor is how trauma is interpreted. The inability to attend a traditional funeral and mourn can greatly impact the intensity and nature of PTSD symptoms. 

Social contexts may impact PTSD as well. Living among perpetrators of violence who remain unpunished by the legal system denies a sense of closure and instills fear in individuals. Factors such as acculturative stress are more common in certain cultural groups as well, as, for example, with immigrants.

Moreover, it is also interesting to note that the symptoms of PTSD themselves can vary culturally. Avoidance and numbing symptoms and distressing dreams are also related to how different cultures express and cope with stress, and somatic symptoms like dizziness or shortness of breath may be more or less prevalent in individuals, depending on their cultural backgrounds. For instance, panic attack symptoms may be a more common feature of PTSD since that culture associates panic with specific panic-like conditions.

Gender Disparities in PTSD Prevalence and Duration

Statistically, for females, there is not only a higher chance of developing PTSD than males, but the disorder is also experienced for a greater amount of time. This is partly due to females facing a higher probability of experiencing certain violent events. However, if males and females are exposed to the same traumatic stressors, the differences in the occurrence of PTSD tend to diminish. 

On the other hand, some studies such as a study published in the Psychological Bulletin by the American Psychological Association in 2007, argue that women tend to perceive threats and loss of control more strongly, potentially shaping their responses to traumatic incidents. Intriguingly, the discussion also delves into gender-specific brain engagement during threat evaluation, hinting at potential neurobiological mechanisms influencing gender-specific stress responses.

While the traditional notion posits that women’s elevated risk of PTSD stems from the nature of the trauma experienced, the study challenges this assumption and suggests that factors such as age at exposure, perceptions of threat and loss of control, and coping mechanisms could play a crucial role in elucidating the gender disparities in PTSD prevalence.

Suicide Risk

Traumatic events, especially if they are experienced in childhood, significantly increase the risk of suicide. PTSD is a critical factor when assessing the risk of suicide for an individual. A study published in the American Journal of Epidemiology examined the correlation between PTSD and completed suicide in a population-based sample in Denmark from 1994 to 2006. The study found that the risk of suicide in individuals suffering from PTSD was 9.8 times higher than in those without the condition.

Functional Impact of PTSD

People with PTSD often have problems in their social, work, and physical lives. Relationships with family and friends can suffer, income may decrease, they might miss work often, and their education and job performance may decline. A 2021 article in the Journal of Psychiatric Research reviewed 34 studies involving 14,206 people to measure how PTSD affects daily life. The study found that people with PTSD have significant difficulties in many areas compared to healthy people. These difficulties were very noticeable and affected tasks like self-care, moving around, household chores, relationships, work, and community activities. The study also found that these challenges are greater for people with PTSD compared to those with other mental health issues.

The Interplay between PTSD and Co-occurring Disorders

Generally, there is a significant likelihood that individuals suffering from PTSD will also meet the criteria for other mental disorders. Individuals suffering from PTSD are 80% more likely to have symptoms that meet the diagnostic criteria for at least one other mental disorder than those without PTSD. It was observed that among U.S. military personnel deployed in conflicts in the Middle East, the co-occurrence of PTSD and mild Traumatic Brain Injury was 48%. The pattern of co-occurring disorders is different in children than in adults, as the predominant conditions are defiant disorder and separation anxiety.

Efficacy of Cognitive Behavioral Therapy (CBT)   in PTSD

In 2010, a study was conducted and published in the Clinical Psychology Review, which explored the effectiveness of trauma-focused cognitive behavioral therapy (CBT) in treating post-traumatic stress disorder (PTSD). Trauma-focused CBT is a type of therapy that aims to focus on trauma memory and its meaning in individuals with PTSD. According to the study’s findings, trauma-focused CBT and eye movement desensitization and reprocessing (EMDR) showed comparable effectiveness in reducing PTSD symptoms. 

In 2015, a study published in Procedia more decisively argued for the effectiveness of CBT in reducing symptoms of chronic PTSD, depression, and anxiety. The article explained that the main objective of CBT is to alleviate discomfort and improve the overall quality of life for patients. CBT uses a combination of cognitive and behavioral techniques to help individuals identify and modify distorted beliefs that are linked to their PTSD symptoms, aiding in their recovery process. 

Similarly, a study conducted in 2001 among refugees found that both CBT and exposure therapy (E) led to significant reductions in PTSD symptoms, with E resulting in a 48% reduction and CBT leading to a 53% reduction. Both treatments also showed reductions in generalized anxiety (49% for E and 50% for CBT) and depression (54% for E and 57% for CBT). These improvements were maintained at a 6-month follow-up. Therefore, trauma-focused CBT for PTSD symptoms may provide substantial relief and contribute to sustained improvements in anxiety and depression, underscoring its value as a therapeutic intervention for trauma survivors.
