Post-Traumatic Stress Disorder: Navigating the Challenging Waters

In the dark corridors of the human psyche, few processes are as complex and as profoundly impactful as the shadows cast by extreme trauma. Some experiences stch deeply into the psyche, impacting future experience. Post-traumatic stress disorder (PTSD), a shadow that follows the aftermath of trauma, often goes unseen, yet it holds a grip on the lives of many, altering their reality in profound ways. As we delve into the depths of PTSD, we uncover not just the struggles and the pain, but also the resilience of the human spirit and the potential for healing and growth. This article seeks to unravel the enigma of PTSD, shedding light on its causes, manifestations, and the journey towards recovery, with the hope of fostering understanding and offering solace to those who navigate its challenging waters.

What is Post-Traumatic Stress Disorder?

PTSD, or post-traumatic stress disorder, is like a shadow that can follow someone after they’ve been through something really scary or upsetting. Imagine your brain has a file cabinet where it keeps all your memories. Usually, it can sort them out so you can go on with your life. But sometimes, after a really bad experience, the brain gets stuck and keeps thinking about that scary event over and over again. This can make a person feel nervous, have bad dreams, or want to stay away from things that remind them of what happened. It’s like the brain’s alarm system won’t turn off, even when there’s no danger.

Peter Levine, a renowned psychologist and the developer of Somatic Experiencing, explains that trauma “is something that also happens in the body. We become scared stiff or, alternately, we collapse, overwhelmed and defeated with helpless dread. Either way, trauma defeats life” (Levine, 2012).

Lawrence Kolb, a former professor of psychiatry, wrote that terror in fantasy “is indeed as great as terror in fact” (Kolb, 2005).

Historical Reference to Post-Traumatic Stress Disorder

Over the last couple centuries philosophers and scientists have referred to post-traumatic stress disorder by different names such as ‘soldiers heart’ and ‘fright neurosis.’ Many believed that those suffering from its ailments had a weakness of mental constitution.

Sigmund Freud recognized this traumatic condition as arising from an overwhelming stress. Freud proposed that the psyche has mechanisms in place to protect itself from excessive external stimuli, but when these defenses are breached, it can lead to psychological distress, which is a central idea in understanding trauma and its effects. He defined trauma as “a breach in the protective barrier against stimulation, leading to feelings of overwhelming helplessness” (Freud, 1920).

Trauma is More than a Label

Trauma that breaches our protective barriers may arise from a natural disaster, serious accident, combat situation, physical or sexual assault, or any other event perceived as life-threatening. Levine laments “the current terminology, derived largely from the experiences of the Vietnam War, is posttraumatic stress disorder. As PTSD, the universal phenomenon of terror and paralysis—in which the nervous system has been strained to the breaking point, leaving body, psyche and soul shattered—is now fully sanitized as a medical “disorder” (Levine, 2012).

Bessel van der Kolk, M.D., a professor of psychiatry at Boston University School of Medicine and director of the National Complex Trauma Treatment Network. He wrote that traumatic events “leave traces on our minds and emotions, on our capacity for joy and intimacy, and even on our biology and immune systems” (van der Kolk, 2015).

However, treatment and research need a label and unified definitions. So while we need the medical label and definition for practical and professional purposes,

DSM Definition of PTSD

The DSM-5, which stands for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, outlines specific criteria for diagnosing PTSD. Here’s a simplified version of the criteria:

Exposure to Trauma: The person must have been exposed to death, threatened death, serious injury, or sexual violence. This can happen in different ways, like experiencing it directly, witnessing it, learning that a close relative or friend was exposed, or being repeatedly exposed to aversive details of the trauma (like first responders).
Intrusion Symptoms: The traumatic event is persistently re-experienced through unwanted memories, nightmares, flashbacks, emotional distress, or physical reactions after exposure to reminders of the trauma.
Avoidance: The person actively avoids thoughts, feelings, or reminders of the traumatic event.
Negative Changes in Thoughts and Mood: This includes things like not being able to remember parts of the trauma, negative beliefs about oneself or the world, distorted blame of self or others, loss of interest in activities, feeling isolated, or difficulty experiencing positive emotions.
Alterations in Arousal and Reactivity: This refers to symptoms like irritability, risky behavior, hypervigilance, an exaggerated startle response, difficulty concentrating, or sleep disturbances.
Duration: The symptoms must last for more than a month.
Functional Significance: The symptoms cause significant distress or problems in social, occupational, or other important areas of functioning.
Exclusion: The disturbance is not attributable to the physiological effects of a substance or another medical condition (American Psychiatric Association, 2013).

These criteria are used by mental health professionals to help diagnose PTSD in individuals who have experienced a traumatic event¹. It’s important for a thorough evaluation to be conducted by a qualified professional to determine an accurate diagnosis.

Symptoms of PTSD

Common symptoms of PTSD (post-traumatic stress disorder) can be quite distressing and may include:

Re-experiencing Symptoms: These involve reliving the traumatic event through flashbacks, nightmares, and intrusive.
Avoidance Symptoms: People with PTSD may avoid places, activities, or people that remind them of the trauma, and they might also avoid thinking or talking about the event.
Negative Changes in Cognition and Mood: This can manifest as persistent negative beliefs about oneself or the world, distorted feelings like guilt or blame, and a loss of interest in previously enjoyed activities.
Arousal and Reactivity Symptoms: These include being easily startled, feeling tense or “on edge.” The heightened arousal interfere with sleeping, and create a vulnerability to expressing frustrations with angry outbursts.

Children with PTSD might show different symptoms, such as regressive behaviors or delays in development. It’s important for anyone experiencing these symptoms to seek professional help, as effective treatments are available.

Unprocessed Trauma

Unprocessed trauma refers to traumatic experiences that a person has not fully confronted or integrated into their understanding of themselves and the world. When trauma is unprocessed, it means that we can’t adequately digest the intense emotions and memories associated with the traumatic event. Instead, they remain ‘stuck’ in the mind and body, often leading to a variety of symptoms that can disrupt daily life.

This can happen because the brain’s normal process of storing memories gets interrupted by trauma. Instead of being filed away as a past event, the traumatic memory feels current and threatening, triggering the body’s stress response even when there’s no immediate danger. This can lead to symptoms like hypervigilance, flashbacks, and avoidance behaviors.

Unprocessed trauma can also manifest in physical symptoms, such as chronic pain or digestive issues, as the body holds onto the stress. Emotionally, it can lead to feelings of numbness, anxiety, or intense mood swings.

The key to addressing unprocessed trauma is through therapeutic interventions that help the individual process these memories and emotions safely. Effective therapy guides patients through a process of properly addressing trauma, leading to a completed process. Therapy has successfully reduced PTSD symptoms in many individuals, providing relief, and having an immediate impact on their life.

Stress Response and PTSD

The stress response is your body’s way of reacting to a challenge or threat. When you face something stressful, your brain kicks into high gear. Here’s what happens in simple terms:

Alarm Bell Rings: Imagine your brain has an alarm system. When you see or hear something that could be dangerous, like an angry dog or a car speeding towards you, the alarm goes off. This part of your brain is called the amygdala, and it’s really good at spotting trouble.
Command Center Activates: Once the alarm bell rings, another part of your brain called the hypothalamus takes charge. It’s like the boss that tells your body what to do. It sends signals all over your body to get ready for action.
Fight or Flight: Your body now has two choices: to stay and deal with the problem (fight) or run away to safety (flight). Your heart beats faster, your muscles tense up, and you start breathing quickly. This is all to make sure you have enough energy and strength to handle the threat.
Calm Down: After the danger is gone, your body should calm down. Your heart rate goes back to normal, and you start to relax. This is thanks to the parasympathetic nervous system, which is like the brake pedal that slows everything down.

But if the stress keeps happening or your body stays on high alert too long, it can be like a car with the gas pedal stuck down. This can wear you out and lead to health problems like trouble sleeping, headaches, or even heart disease.

See General Adaptation Syndrome for more on this topic

Paralysis and the Stress Response

Another dysfunction that may occur that disrupts the normal stress response is the inability to fight or flee. Some researchers add to the fight or flight response a third response of freeze. The third response is not a ploy of feigning dead to survive but a psychological paralysis in the face of extreme danger without a notable escape route.

Levine wrote, “It is my observation that a precondition for the development of posttraumatic stress disorder is that a person is both frightened and perceives that he or she is trapped.” Levine continues, explaining that the interaction of intense fear and immobility “is fundamental in the formation of trauma, in its maintenance and in its deconstruction, resolution and transformation” (Levine, 2012, p. 58).

The suggestion is that an individual’s inability to respond to the threat creates extreme psychic stress and no path to complete the stress response. The entire cycle is disrupted and remains unfinished.

Predisposition for PTSD

Not everyone that experiences trauma suffers from PTSD. Most integrate the experience into their narrative of life and move forward. Some actually experience post-traumatic growth. For these people, the trauma becomes a catalyst that propels them to new heights. Others are not so lucky.

According to the diathesis stress model, people have an underlying predisposition (diathesis) towards certain psychological conditions, and that the manifestation of these conditions is determined by the presence of stressors. Biologically, some people are vulnerable to stress. The vulnerability lies hidden in the synaptic connection and structure of the brain until an event significant enough to awaken the condition collides with the individual and activates the disorder.

See Diathesis Stress Model for more on this theory

Life History

However, biological predisposition is not the sole factor. Life histories play a significant role as well. Randolph Nesse explains: “Those who developed PTSD after the trauma were more likely to have had early separation from parents, a family history of anxiety, or preexisting anxiety or depression.” He continues, by adding that the strongest predictor of developing PTSD “was a history of past exposure to traumatic events, and traumatic events were more likely to happen to people who had previously experienced something terrible” (Nesse, 2019).

Steven Southwick and Dennis Charney remind that: “It is important to emphasize that resilience to stress and susceptibility to develop PTSD undoubtedly result from complex interactions between multiple genes and multiple environmental factors rather than any single gene variant” (Southwick & Charney, 2017).

It is one of the terrible paradoxes of life. Those most likely to suffer most from trauma are those that experienced trauma. Moreover, those that have traumatic childhoods are more likely to encounter situations where trauma may occur. The nasty side of reciprocal determination exposes an ever-multiplying web of danger and trauma for the most vulnerable in our society.

Social networks provide a buffer against the severe impact of trauma. Close, supportive people strengthen resilience. Southwick and Charney report that “strong social support has been linked to a decreased chance of developing depression, an increased likelihood of recovering from depression, improved psychological outcomes after severe traumas such as childhood sexual abuse, and reduced rates of combat-related PTSD” (Southwick & Charney, 2017).

People matter. Relationships are essential not only to wellness but in preventing illness. Some research suggests that supportive relationships often increase the body’s production of oxytocin which “not only fosters trust but may also protect against potentially harmful chemicals (e.g., cortisol) that are released during stress” (Southwick & Charney, 2017). Research such as this, gives a little more credence to Barbara Fredrickson’s undoing hypothesis. which suggests that positive emotions help undo the ill effects of stress.

Positive Emotions

Fredrickson explains: “Negative emotions that create urges for specific action requiring substantial physical energy (e.g., attack, flee) also produce heightened cardiovascular reactivity that redistributes blood flow to relevant skeletal muscles.” She continues saying that positive emotions, on the other hand, are “often characterized by relative lack of autonomic reactivity” (Fredrickson et al., 2000, p. 238).

Robert W. Levenson suggested that the evolutionary meaning of positive emotions “might be to function as efficient ‘undoers’ of states of ANS arousal produced by certain negative emotions” (Levenson, 1988, p. 23).

The causes of PTSD are complex. Vulnerabilities begin in the womb. The child develops habits that protect and weaken resilience throughout their lives. Unplanned and unprovoked exposures to trauma significantly change the texture and color of internal processes. All these threads intricately weave together, creating a protective wall or a vulnerable gate. We each have a threshold of what we can withstand. When that threshold is breached, psychological harm is inevitable.

How we respond to the harm also varies according to skills and resources.

Neurobiology of PTSD

The neurobiology of post-traumatic stress disorder (PTSD) is a field that delves into the intricate workings of the brain following traumatic experiences. At the heart of PTSD’s neurobiological underpinnings is the dysregulation of the fear response. A complex interplay between various brain regions mediates the fear response.

Amygdala

Central to this dysregulation is the amygdala, a structure deeply embedded within the brain’s temporal lobes, which plays a pivotal role in processing fear and emotional memories. In individuals with PTSD, research has shown that the amygdala is often hyperactive, leading to heightened fear responses and the persistent re-experiencing of trauma.

Prefrontal Cortex

Conversely, the prefrontal cortex—the brain’s executive control center—is typically underactive in PTSD sufferers. This area is responsible for regulating emotions and exerting control over the amygdala. When its function is compromised, as seen in PTSD, the ability to manage fear and anxiety is significantly diminished. The diminished capacity of the prefrontal cortex contributing to the hallmark symptoms of the disorder.

Hippocampus

Another key player is the hippocampus. The hippocampus contributes to forming and retrieving memories. Studies have shown that individuals with PTSD may have a smaller hippocampus, which can affect the processing and storage of traumatic memories. Joseph LeDoux, a neuroscientist renowned for his research on survival circuits, wrote that when “stress continues, hippocampal cells begin to degenerate and ultimately die. These changes appear to account in part for the memory disturbances typical of stress-related psychiatric conditions such as posttraumatic stress disorder, or PTSD, and depression” (LeDoux, 2003).

Neurotransmitters

Neurobiological models also highlight the role of neurotransmitters and hormones, such as cortisol and norepinephrine. These neurotransmitters play a role in the body’s stress response. Abnormal levels of these chemicals can further exacerbate the symptoms of PTSD, influencing memory formation, mood, and arousal levels.

Advancements in neuroimaging techniques have allowed researchers to observe these changes in the brain, providing a clearer picture of the neurobiological landscape of PTSD. Understanding these mechanisms is crucial for developing effective treatments and interventions for those affected by this challenging condition.

For a more detailed exploration of the neurobiology of PTSD, including the latest research and therapeutic implications, I recommend consulting specialized literature and peer-reviewed articles in the field.

Treatments for PTSD

The landscape of treatments for post-traumatic stress disorder (PTSD) is evolving, with both established and emerging therapies showing promise. Here are some of the notable treatments:

Psychotherapy:

Cognitive Behavioral Therapy (CBT): This therapy aims to change negative thinking patterns and behaviors associated with PTSD. Techniques include recognizing symptoms’ origins and modifying the psychological and physical reactions that occur when reminded of trauma.
Psychodynamic Psychotherapy: Focuses on how trauma has impaired emotional management and self-soothing during stress.
Somatic Experiencing: Developed by Peter Levine, this body-focused therapeutic approach helps release the physical tension that remains in the aftermath of trauma.
Exposure Therapy: A form of CBT that involves safely confronting the trauma-related memories and feelings to reduce their power.
Eye Movement Desensitization and Reprocessing (EMDR): Practitioners propose that this treatment works with the brain’s natural healing abilities, helping to move the “stuck” traumatic memories into normal memory storage, so they no longer cause intense distress. Research has shown that EMDR can be very effective and often works faster than other therapy methods. Some studies have reported that up to 90% of single-trauma victims no longer had PTSD after just a few sessions of EMDR therapy.
Cognitive Processing Therapy: A specific type of cognitive-behavioral therapy that helps individuals with PTSD reframe negative thoughts about the trauma and its aftermath.
NeuroAffective Relational Model (NARM): Research considers NARM particularly effective for individuals who have experienced complex trauma, which often involves multiple traumatic events or adverse childhood experiences. The therapy uses a relational and developmental approach, incorporates somatic awareness, and works on shame and self-regulation.

Medications:

Antidepressants: Often prescribed to help manage symptoms of depression and anxiety associated with PTSD.
Anti-anxiety Medications: Can help reduce the intense periods of anxiety and panic.
Mood Stabilizers: Physicians may prescribe mood stabilizers to control mood swings.

Emerging Treatments:

MDMA-Assisted Psychotherapy: Involves a few administrations of MDMA in conjunction with talk therapy. Early clinical trials have shown promising results in reducing PTSD symptoms.
Repeated Ketamine Infusions: Ketamine, an NMDA receptor antagonist, has been studied for its potential to alleviate PTSD symptoms.
Theta Burst Stimulation: A form of brain stimulation therapy that researchers are exploring for its effectiveness in treating PTSD.
Mindfulness and Meditation-Based Interventions: These non-pharmacological approaches are gaining attention for their potential to help individuals with PTSD.

It’s important to note that while some of these treatments are still experimental, they represent a growing hope for an expanding array of options for those affected by PTSD. For individuals seeking treatment, it’s crucial to consult with healthcare professionals to determine the most appropriate therapy. We are individuals. Accordingly, treatment should be based on the individuals specific needs and circumstances.

Associated Concepts

Fight or Flight Response: This is the body’s immediate reaction to perceived danger, preparing one to either confront or flee from the threat. It’s a survival mechanism that involves physiological changes like increased heart rate and adrenaline release.
Acute Stress Disorder: This is a condition that can occur in the immediate aftermath of a traumatic event, with symptoms similar to PTSD but typically lasting for a shorter duration, from days to one month.
Attachment Theory: This concept explores how early relationships with caregivers can influence an individual’s ability to form secure relationships and manage stress and trauma later in life.
Startle Response: This refers to a complex, involuntary reaction to sudden stimuli, deeply rooted in survival instincts. It involves rapid movements and serves as a defense mechanism. The response varies across individuals and plays a role in conditions like PTSD.
Resilience: This refers to the ability to adapt and recover from adversity or trauma. Psychological resilience can be a protective factor against developing PTSD.
Secondary Traumatization: This occurs when an individual is indirectly exposed to trauma through a close relationship with someone who has experienced trauma, or through professional duties like first responders or therapists.
Stress Management: This refers to the techniques and strategies used to control, reduce, and cope with the negative effects of stress. It involves identifying stress triggers, implementing healthy coping mechanisms, and making lifestyle changes to enhance well-being.

A Few Words by Psychology Fanatic

In conclusion, Post-Traumatic Stress Disorder (PTSD) is a complex mental health condition that can have a profound impact on individuals who have experienced or witnessed traumatic events. Understanding the description and symptoms of PTSD is crucial in identifying and addressing this condition effectively. Through various treatment approaches such as therapy, medication, and support from mental health professionals, individuals with PTSD can learn to manage their symptoms. Accordingly, better managed symptoms lead to improvement in their overall well-being.

It is essential for those struggling with PTSD to seek help and support. Help is available to guide those suffering to a path of healing and recovery. By raising awareness, providing education, and offering compassionate care, we can work together to support those affected by PTSD on their journey towards healing and resilience.
