Post-Traumatic Stress Disorder (PTSD) and Alcohol Use Disorder (AUD) are often found to co-occur. People with PTSD are more likely to develop an unhealthy relationship with alcohol, and those with AUD are more likely to experience a traumatic event that leads to PTSD. Research has found that 1 in 10 Vietnam veterans with PTSD also had issues with alcohol, such as binge drinking, which they developed in response to trauma. This is a higher statistic than the average individual who does not experience PTSD. Excessive alcohol consumption can be a form of avoidance symptoms, as people with PTSD may drink to relieve their symptoms of anxiety, irritability, and depression.

What You'll Learn

Trauma survivors and alcohol use
Trauma survivors often experience symptoms such as heightened anxiety, hypervigilance, and trouble sleeping. To cope with these distressing symptoms, some may turn to alcohol to "numb the pain". This is known as self-medication, where alcohol is used as a coping mechanism to deal with the emotional and physical pain caused by trauma.
Research has shown a strong correlation between Post-Traumatic Stress Disorder (PTSD) and Alcohol Use Disorder (AUD). Individuals with PTSD are more likely to develop an alcohol dependency, and excessive alcohol consumption can be a sign of this disorder. For example, in a study of Vietnam combat veterans with PTSD, more than half exhibited signs of alcohol addiction that developed in response to trauma. The Department of Veterans Affairs reports that about 63% of veterans diagnosed with AUD also meet the criteria for PTSD. This relationship between PTSD and AUD is not limited to veterans but extends to anyone exposed to trauma.
There are several reasons why trauma survivors with PTSD may engage in excessive alcohol consumption. Firstly, alcohol may provide temporary relief from intrusive thoughts and emotions related to trauma. It can numb the emotional and physical pain associated with traumatic experiences. Secondly, after a traumatic event, individuals often experience a period of endorphin withdrawal, which can lead to emotional distress and other PTSD symptoms. Alcohol increases endorphin activity, so drinking can compensate for this withdrawal and help avoid associated negative feelings. This is known as the Endorphin Compensation Hypothesis (ECH).
It is important to recognize that using alcohol as a coping mechanism can lead to alcohol dependency and worsen existing PTSD symptoms. Binge drinking, for instance, can increase feelings of emotional numbness, irritability, and hyperarousal. Furthermore, alcohol abuse can make PTSD treatment less effective and increase the risk of experiencing further traumatic events due to involvement in high-risk situations. Therefore, it is crucial for trauma survivors to seek professional help and explore alternative coping strategies, such as Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) and support groups, to manage their PTSD symptoms effectively.

PTSD and AUD comorbidity
Excessive alcohol consumption is indeed a sign of post-traumatic stress disorder (PTSD). The co-occurrence of PTSD and alcohol use disorder (AUD) has been well-documented over several decades and across diverse populations. Research has consistently shown that individuals with PTSD are more likely to experience AUD compared to those without PTSD. This relationship between PTSD and excessive alcohol consumption is not limited to any specific population but has been observed in various groups, including veterans, firefighters, women, and people with substance use disorders (SUDs).
The link between PTSD and AUD can be understood from two perspectives. One perspective is the self-medication hypothesis, which suggests that individuals with PTSD may turn to alcohol as a way to cope with their traumatic experiences and relieve symptoms of anxiety, irritability, and depression. The other perspective is supported by research indicating that individuals with AUD or SUD are more likely to be exposed to traumatic events and subsequently develop PTSD. These two areas of research represent two separate but interconnected relationships between PTSD and AUD.
The co-occurrence of PTSD and AUD has been found to result in greater symptom severity and poorer quality of life for individuals experiencing both disorders. Additionally, the comorbidity of PTSD and AUD has been associated with poorer treatment outcomes and shorter periods of abstinence post-treatment. However, it is important to note that there is currently a lack of evidence-based treatments specifically designed for individuals with comorbid PTSD and AUD. While some pharmacological treatments have shown promising results, more systematic research is needed to develop effective interventions for this dual diagnosis.
The endorphin compensation hypothesis (ECH) provides a potential explanation for the link between PTSD and AUD. According to this hypothesis, alcohol consumption after traumatic events compensates for the decrease in endorphin activity that occurs during endorphin withdrawal. This withdrawal can lead to emotional distress, contributing to PTSD symptoms. As alcohol increases endorphin activity, drinking may be used to avoid the negative emotional consequences of endorphin withdrawal following trauma.
In summary, the comorbidity of PTSD and AUD is a well-documented phenomenon with significant impacts on individuals' lives. While excessive alcohol consumption can be a sign of PTSD, it is important to recognize that the relationship between these disorders is complex and bidirectional. Further research and the development of evidence-based treatments are crucial to effectively address the challenges faced by individuals experiencing comorbid PTSD and AUD.

Self-medication and avoidance
Alcohol consumption can increase endorphin activity, which helps to compensate for the endorphin withdrawal that follows a traumatic experience. This is known as the Endorphin Compensation Hypothesis (ECH). The ECH explains why alcohol consumption increases after trauma, rather than before or during the event.
The desire to avoid thinking about traumatic events or experiencing related emotions may also cause someone with PTSD to drink alcohol. Alcohol can provide temporary relief from intrusive thoughts, but as the effects wear off, negative emotions associated with alcohol withdrawal can intensify PTSD symptoms. This can create a cycle where the individual continues to drink excessively to avoid these negative feelings, which may put them at risk of experiencing further trauma due to the involvement of high-risk situations.
Research has found a strong association between PTSD and alcoholism, with individuals with PTSD being more likely to develop an alcohol dependency. For example, studies have shown that one out of every ten Vietnam veterans with PTSD also had issues with alcohol, such as binge drinking, which they developed in response to trauma. Binge drinking can increase symptoms of PTSD, such as emotional numbness, irritability, and feelings of being "on guard".
The link between PTSD and alcohol use disorder (AUD) is well-established, affecting the lives of millions of men and women. It is important to recognize the signs of PTSD and alcoholism in loved ones and to seek treatment for these co-occurring disorders. Treatment options include trauma-focused cognitive-behavioral therapy and support groups, which can help individuals develop healthier coping mechanisms.

Endorphin compensation hypothesis
Trauma and alcoholism often go hand in hand. However, this is not because they inherently cause each other, but because alcohol is frequently used to self-treat the symptoms of trauma. This is known as the endorphin compensation hypothesis.
Endorphins are a type of hormone that helps block pain and induces feelings of happiness and contentment. During a traumatic event, endorphin levels increase in the brain, numbing the emotional and physical pain of the trauma. However, after the trauma is over, endorphin levels gradually decrease, leading to a period of endorphin withdrawal that can last from hours to days. This withdrawal can cause emotional distress and contribute to symptoms of post-traumatic stress disorder (PTSD).
The endorphin compensation hypothesis suggests that people use alcohol after a traumatic event to compensate for the endorphin deficiency and relieve the symptoms of emotional distress. Alcohol increases endorphin activity, providing a temporary relief from the negative effects of endorphin withdrawal. However, this can create a vicious cycle, as more alcohol is needed over time to prevent subsequent endorphin withdrawal symptoms. This cycle can lead to alcohol addiction, with individuals needing to consume more alcohol to feel the same effects.
Research has supported this hypothesis, finding that alcohol consumption increases after trauma rather than during or in anticipation of it. For example, in a study with rats, there were dramatic increases in alcohol preference on the days following exposure to shocks, termed the "happy hour effect". Similarly, a study of Vietnam combat veterans with PTSD showed that their alcohol use generally began after the onset of PTSD symptoms.
The endorphin compensation hypothesis has important implications for understanding and treating co-occurring PTSD and alcoholism. It highlights the complex relationship between trauma, endorphins, and alcohol use, providing insight into why some individuals turn to alcohol as a coping mechanism following traumatic experiences.

Treatment options for PTSD and AUD
Post-Traumatic Stress Disorder (PTSD) and Alcohol Use Disorder (AUD) are chronic, debilitating psychiatric conditions that frequently co-occur. The link between the two disorders has been observed beyond Vietnam veterans to include veterans of other wars and anyone exposed to trauma. The high rates of disability, physical and mental health problems, and healthcare utilization associated with co-occurring AUD and PTSD pose a significant economic burden globally.
Individuals with co-occurring AUD and PTSD face a more complex treatment course and poorer treatment outcomes compared to those with either disorder alone. They also have an increased risk of developing other psychiatric problems, such as depression and anxiety, and experience impaired vocational and social functioning. Therefore, developing effective interventions to treat co-occurring AUD and PTSD is a public health priority.
Pharmacological treatments are often a first-line approach for individuals with PTSD or AUD. However, the literature on the use of US Food and Drug Administration (FDA)-approved medications for the dual diagnosis of PTSD and AUD is limited and inconclusive. While medications should still be considered for treating individuals with comorbid conditions, there is a clinical need to explore other options. Anticonvulsants like topiramate and the alpha-1 adrenergic receptor antagonist prazosin have shown promising results in reducing PTSD and AUD symptoms in individuals with comorbidity.
Behavioral interventions are also a critical component of treatment for co-occurring AUD and PTSD. Trauma-informed, manual-guided, integrated cognitive-behavioral treatments have been developed to concurrently address symptoms of both conditions. These integrated treatments are now widely available, providing additional options for individuals and healthcare providers. Some evidence-based behavioral interventions for comorbid AUD and PTSD include:
- Prolonged exposure therapy
- Cognitive processing therapy
- Eye movement desensitization and reprocessing
- Psychotherapy incorporating narrative exposure
- Present-centered therapy
- Relapse prevention
- Contingency management
- Motivational enhancement
- Couples therapy
- 12-step facilitation
- Community reinforcement
- Mindfulness practices
While these behavioral interventions have shown promise, high treatment dropout rates and persistent symptoms after treatment remain challenges. Future studies should focus on rigorous testing of existing treatment options and evaluating treatments that combine pharmacological, behavioral, and alternative interventions to optimize treatment efficacy for individuals with a dual diagnosis of PTSD and AUD.
