PTSD and Substance Abuse |  Dual Diagnosis Treatment in St. Louis

Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after a person has experienced or witnessed a traumatic event, such as a natural disaster, accident, or act of violence. There’s a wide range of distressing symptoms that occur with PTSD, including intrusive thoughts, negative mood changes, and heightened reactivity.[1]

The symptoms of PTSD can be intense and disruptive to day-to-day life, leading some people to rely on substances to numb emotions, calm feelings of fear or anxiety, and relax in social situations. However, this can lead to an addiction to drugs or alcohol, as well as worsening symptoms of PTSD.
At Engage Wellness, we offer dual diagnosis treatment in St. Louis for PTSD and substance abuse. Our integrative approach addresses the underlying trauma and the interplay between PTSD and addiction to help you reach recovery.

Key Points

  • Post-traumatic stress disorder (PTSD) is a mental health condition caused by experiencing or witnessing a traumatic event like a natural disaster or assault.

  • People with PTSD may self-medicate symptoms, leading to an increased risk of developing a co-occurring addiction.

  • Treating PTSD and addiction requires a comprehensive, trauma-informed approach that addresses both conditions and how they influence and impact one another.

What Is PTSD?

PTSD is a disorder that’s classified as a trauma- and stressor-related disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). PTSD may be caused by experiencing a traumatic event directly, such as a natural disaster, accident, or abuse, or witnessing a traumatic event firsthand.

Traumatic or life-threatening events may cause post-traumatic stress symptoms, such as heightened reactivity or intrusive memories, but this is distinct from PTSD. When the symptoms persist for more than a month and disrupt daily life, it’s PTSD. Based on research, about 90% of people experience a traumatic event in their lives, but only about 10% of people develop PTSD.[2]

Some people are at an increased risk of developing PTSD. Due to the types of traumas that affect women, they’re more likely to experience PTSD than men.[3] PTSD is also more common for combat veterans than civilians or veterans who were not in an active combat zone.

The risk factors for PTSD include:[4]

  • Being in a situation that causes extreme fear or helplessness

  • Exposure to trauma, especially in childhood

  • Suffering a physical assault or injury

  • Witnessing the injury or death of someone else

  • Experiencing additional stress related to a traumatic event, such as losing a loved one or losing a home in a fire

  • Family history of mental illness or substance abuse

  • A lack of support after a trauma

The signs and symptoms of PTSD can vary in their severity or type, but some common ones include:[5]

  • Changing routine to avoid triggers, such as avoiding crowds or driving

  • Recurrent, unwanted thoughts or memories of the traumatic event, including flashbacks or nightmares

  • A heightened state of arousal or reactivity that can affect sleep, mood, or stress

  • Feeling guilty or experiencing negative thoughts related to the trauma

Addiction and Interaction with PTSD

Trauma and substance use have a clear link, and that link is stronger with PTSD and substance use disorders (addiction). These conditions are common co-occurring disorders, or dual diagnosis, which refers to the presence of a mental health condition and substance use disorder. Based on research, 44.6% of individuals with lifetime PTSD met the criteria for a substance use disorder involving drugs or alcohol.[6] The research also revealed that having PTSD increases the risk of developing a substance use disorder.

PTSD and Substance Use Disorder Causes

PTSD and substance use disorder may co-occur for several possible reasons:[7]

  • Self-medicating symptoms: Some studies indicate that PTSD symptoms like anxiety, fear, intrusive memories, and reactivity can cause people to use drugs or alcohol to relieve symptoms, relax, or calm triggers.

  • Brain changes: The brain undergoes changes when there’s a mental health disorder like PTSD or trauma, which can enhance the euphoria and pleasure derived from drugs and alcohol and reinforce drug abuse.

  • Common risk factors: PTSD and addiction have overlapping risk factors, including trauma, stress, and genetic predisposition.

  • Engaging in risky behaviors: People who use substances may engage in riskier behaviors because of lowered inhibitions or feelings of invincibility, which can increase the risk of experiencing trauma and developing PTSD.

Treatment Challenges with PTSD and Addiction

Dual diagnosis, like PTSD and addiction, can add complexity and challenges to treatment. Many PTSD symptoms, including emotional dysregulation, insomnia, and anxiety, are also common symptoms of substance use or withdrawal. Identifying which condition came first and which symptoms belong to which condition can complicate diagnosis and treatment plans.

It’s difficult for people with PTSD to break the cycle of self-medication as well, especially if it provides temporary relief from symptoms like flashbacks or emotional pain. However, any relief that comes from substance use is short-lived, and using substances can even make symptoms worse.

There are additional challenges in treatment as well. If PTSD is related to trauma like physical or sexual abuse or assault, it may be difficult for someone struggling with PTSD to open up, trust others, and feel completely safe and secure in a treatment community. They may not engage fully in treatment sessions, inhibiting progress. Triggers are also possible in group treatment settings, which can fuel symptoms.
