Understanding Trauma and Post-Traumatic Stress Disorder (PTSD): How Trauma Presents Through Other Mental Health Disorders

Author: Erik Turley, LMFT

Introduction

Trauma is a deeply distressing or disturbing experience that can have lasting effects on an individual’s mental and emotional well-being. One of the most significant consequences of trauma is Post-Traumatic Stress Disorder (PTSD), a mental health condition that can develop after experiencing or witnessing a traumatic event. However, the impact of trauma doesn’t stop at PTSD alone. Trauma can manifest in various ways and often leads to or exacerbates other mental health disorders. This article will explore how PTSD is connected to other mental health issues and how it can present itself through them.

What is PTSD?

Before diving into the relationship between PTSD and other mental health disorders, it’s important to understand what PTSD is. PTSD is a mental health condition that some people develop after experiencing or witnessing a traumatic event, such as a natural disaster, accident, war, or assault (Kilpatrick et al., 2013). Individuals with PTSD often experience symptoms such as flashbacks, nightmares, severe anxiety, and uncontrollable thoughts about the event (Yehuda, 2002). These symptoms can be intense and long-lasting, significantly interfering with daily life.

Trauma and Its Broader Impact on Mental Health

Trauma affects everyone differently, and while some people may develop PTSD, others might experience different mental health issues or a combination of disorders. The experience of trauma can lead to a range of emotional and psychological problems, often in conjunction with PTSD. This phenomenon is known as comorbidity, which refers to the presence of two or more disorders in the same individual (Kessler et al., 2020).

The Link Between PTSD and Other Mental Health Disorders

1. PTSD and Depression

One of the most common mental health disorders that co-occurs with PTSD is depression. Depression is a mood disorder characterized by persistent feelings of sadness, hopelessness, and a lack of interest in life (Campbell et al., 2023). Research has shown that individuals with PTSD are at a higher risk of developing depression, with studies indicating that nearly half of those with PTSD also suffer from depression (Karam et al., 2014).

The reasons for this link are complex, but it is believed that the overwhelming stress and emotional pain caused by trauma can lead to the feelings of despair and hopelessness that characterize depression (Friedman et al., 2011). The traumatic memories and the avoidance behaviors typical of PTSD can also contribute to the isolation and withdrawal seen in depression (Resick et al., 2016).

2. PTSD and Anxiety Disorders

Anxiety disorders are another group of mental health conditions that commonly occur alongside PTSD. These include disorders like generalized anxiety disorder (GAD), panic disorder, and social anxiety disorder. Anxiety disorders are characterized by excessive fear, worry, and physical symptoms such as a rapid heartbeat and sweating (Bisson et al., 2015). Trauma can heighten the sense of danger and threat in the world, leading to chronic anxiety. For instance, someone who has experienced a traumatic event might develop a heightened state of alertness, constantly feeling on edge, which is a common symptom of both PTSD and anxiety disorders (North & Pfefferbaum, 2013).

3. PTSD and Substance Abuse

Substance abuse, which refers to the harmful or hazardous use of psychoactive substances like alcohol and drugs, is another condition frequently seen in individuals with PTSD. People with PTSD may turn to substances as a way to cope with their distressing symptoms, such as flashbacks or anxiety. Unfortunately, this often leads to a cycle where substance use worsens PTSD symptoms, leading to more substance use in an attempt to manage the increased distress (Breslau et al., 2008). Studies have found that the use of drugs and alcohol as a coping mechanism is common among trauma survivors, particularly those who have not received proper treatment for their PTSD (Hoge et al., 2007).

4. PTSD and Dissociative Disorders

Dissociative disorders involve disruptions or discontinuity in a person’s thoughts, memories, surroundings, and identity. Dissociation is often a way of mentally escaping from the pain of trauma (Sar et al., 2007). For example, a person with PTSD might experience dissociative amnesia, where they cannot recall important aspects of the traumatic event, or depersonalization, where they feel disconnected from themselves (Lanius et al., 2006). Research has shown that dissociation is a common symptom in individuals with PTSD, particularly those who have experienced complex trauma, such as prolonged abuse or captivity (Stein et al., 2013). Dissociation can make it difficult for individuals to process their trauma, often complicating recovery (Herman, 1992).

5. PTSD and Borderline Personality Disorder (BPD)

Borderline Personality Disorder (BPD) is a mental health disorder characterized by unstable moods, behavior, and relationships. Individuals with BPD often have intense episodes of anger, depression, and anxiety that can last from a few hours to a few days (Cloitre et al., 2014). There is a significant overlap between PTSD and BPD, especially in individuals who have experienced severe and prolonged trauma, such as childhood abuse (Van Der Kolk, 2005). People with both PTSD and BPD may struggle with emotional regulation, have difficulties in relationships, and experience feelings of emptiness and abandonment. Some researchers argue that BPD might be better understood as a form of complex PTSD, which is a type of PTSD that occurs after prolonged and repeated trauma (Ford & Courtois, 2009).

The Importance of Early Intervention and Treatment

Understanding the relationship between PTSD and other mental health disorders is crucial for providing effective treatment. Early intervention can help prevent the development of additional mental health issues and can significantly improve outcomes for individuals with PTSD. Treatments for PTSD often involve a combination of psychotherapy (talk therapy) and medication. Some of the most effective therapies include the following:

1. Cognitive Behavioral Therapy (CBT): CBT helps individuals change negative thinking patterns and develop healthier ways of coping with their trauma-related thoughts and behaviors. It is one of the most widely used therapies for PTSD and has been shown to be highly effective (Resick et al., 2016).

2. Eye Movement Desensitization and Reprocessing (EMDR): EMDR is a therapy that helps people process and integrate traumatic memories by using bilateral stimulation (often through guided eye movements). During EMDR sessions, the therapist guides the client to recall distressing memories while focusing on an external stimulus. This process helps reduce the intensity of traumatic memories and the associated emotional distress, making it easier for individuals to process these memories in a healthier way (Mavranezouli et al., 2024).

3. Internal Family Systems (IFS): IFS is a type of therapy that views the mind as being made up of multiple parts, each with its own perspective, emotions, and memories. In the context of trauma, certain parts may hold onto painful memories or beliefs. IFS therapy helps individuals access and heal these parts by fostering self-compassion and understanding. By doing so, individuals can achieve a sense of internal harmony and reduce the symptoms of PTSD (Schwartz & Sweezy, 2020).

4. Brainspotting: Brainspotting is a relatively new therapy that identifies points in the visual field where a person’s gaze can help access unprocessed trauma in the brain. The idea is that “where you look affects how you feel,” and by identifying a specific spot in the visual field, therapists can help clients focus on and process deeply embedded trauma. This method is particularly effective for those who may have difficulty accessing traumatic memories through traditional talk therapy (Grand, 2013).

5. Dialectical Behavior Therapy (DBT): Originally developed for Borderline Personality Disorder, DBT is increasingly used to treat PTSD, especially in individuals who experience intense emotions and behaviors as a result of trauma. DBT combines cognitive-behavioral techniques with mindfulness practices to help individuals regulate emotions, tolerate distress, and improve interpersonal relationships. For trauma survivors, DBT can be especially beneficial in managing the intense emotions that arise from traumatic memories and in reducing self-destructive behaviors (Linehan, 2014).

Conclusion

Trauma can have far-reaching effects on mental health, leading not only to PTSD but also to a range of other mental health disorders. Recognizing the signs of PTSD and understanding its connections with other conditions like depression, anxiety, substance abuse, dissociation, and borderline personality disorder is essential for providing comprehensive care. Fortunately, there are a variety of effective therapies available, such as EMDR, IFS, Brainspotting, and DBT, that can help individuals process their trauma and lead fulfilling lives. If you or someone you know is struggling with the aftermath of trauma, it is important to seek help from a mental health professional. With the right support and treatment, recovery is possible, and individuals can learn to manage their symptoms and live meaningful lives.
