What you need to know about the relationship between PTSD, trauma, and substance abuse

Posttraumatic stress disorder (PTSD) and addiction are two very different challenges that are sometimes experienced at the same time. People are often curious about the ways that these two struggles overlap.  There are actually several ways that PTSD and substance use go together.

Substances as a solution

People who have PTSD struggle with anxiety and fear, isolation, and sleep difficulties.  Substance use can, understandably, seem like a solution.

Using alcohol might help someone who feels on guard all the time to be able to relax.  Benzodiazepines or marijuana might be used to help individuals who suffer from trauma to fall asleep.  People with PTSD may use substances to avoid thoughts, feelings, or memories associated with the traumatic event.

Research suggests that the relief from substances is short-lived and does not permanently improve the experience of individuals with PTSD, even if it does provide some temporary aid.  In fact the reality is quite the opposite – avoiding symptoms actually helps to maintain the symptoms of PTSD in the long run. The more that trauma-related thoughts and feelings are avoided, the worse symptoms become.

PTSD often leads to negative views of other people or the world, and as a result people with PTSD sometimes feel quite disconnected from friends and family. Using alcohol or other substances may seem like a good way to temporarily suspend those negative beliefs and connect with others.  Again, although using substances may temporarily help someone feel the connection to others that they’re craving, this is not a permanent solution and there are often unintended side effects that wreak havoc in their lives.

Substance abuse sometimes causes trauma

Substance use can, unfortunately, lead to further trauma.

Substances themselves can have effects that can be traumatic, for example a terrifying acid trip or an accidental overdose.  In a similar way, when people are under the influence of substances, their inhibitions are lower and so they are more likely to get into situations where traumatic events occur.  It’s common for people who are under the influence of substances not to feel the full impact of the trauma until later.

It’s important to note that it is less common for substance abuse to lead to trauma; much more often individuals have traumatic experiences and then begin using substances as a way to cope.   They may then be more susceptible to those additional traumatic experiences for a number of reasons, including environmental factors and reduced inhibition when under the influence.

Treatment solutions for both PTSD and substance abuse

When considering the co-occurrence of PTSD and substance abuse, it makes a lot of sense that these disorders go together.  Substance use promises quick relief from pain, and the pain of trauma can sometimes seem intolerable.  However, using substances rarely provides any kind of long term relief and can have a number of negative consequences.

The good news is that a number of effective treatments for co-occurring PTSD and substance abuse have been developed and there are specialists who are trained to help.  Treatment with a qualified professional is a critical part of healing and creating the life that those who suffer from trauma and substance abuse desire and deserve.

Psychotherapy Changes the Brain, Too: A Look at PTSD Treatment

It has become fashionable nowadays in psychotherapy circles to talk about neuroscience and interventions that target the brain. Some writers refer to this bias as “neurocentrism,” the notion that our behavior is best explained by locating it in the brain.

There’s a treatment for posttraumatic stress disorder (PTSD) called Eye Movement Desensitization and Reprocessing (EMDR) that anticipated this trend 20 years ago by using gimmicky neurological language as window dressing to sell the idea that it uniquely effects the brain. This marketing has been really effective, as EMDR has become a well-known “brand name” treatment even though there’s no evidence it’s more effective than other trauma-focused approaches. What people don’t often realize is that psychotherapy has always impacted the brain because making changes in how we think and behave affects the brain.

A new study about post-traumatic stress disorder (PTSD) shows how psychotherapy changes the brain. PTSD consists of a series of struggles (e.g., intrusive thoughts, irritability) that can develop after someone experiences one or more traumatic events. Many people recover after a trauma, but about 10% may develop problems that don’t go away without treatment. In this study, researchers looked at changes in the brain and gene expression before and after cognitive behavioral therapy for PTSD.

The Study

Researchers treated 39 people with PTSD with twelve 90-minute sessions of trauma-focused cognitive behavioral therapy (CBT). Brain scans and blood draws were taken before and after treatment. I found several results really interesting.

CBT Increases Hippocampus Volume

One finding is that there was an actual change in brain matter. The hippocampus is a part of the brain involved in memory. In this study, the size of the hippocampus increased by the end of treatment and these changes were related improvement in PTSD symptoms. The hippocampus can be directly impacted by high levels of long-term stress—such as PTSD—and has been shown to atrophy under these conditions. It appears that psychotherapy can help undo these changes.

The authors note that a prior study did not find any change in hippocampus volume following therapy for PTSD. They note that in the other study, the participants were more severe and had more chronic PTSD; consequently, they speculate that earlier intervention may be extremely important in bringing about improvements.

Changes in Gene Expression

The other biological marker of change the researchers looked at was the FKBP5 gene. Genes are outside my area of expertise, so I’ll try to summarize the results as accurately as I can. Apparently there’s evidence that FKBP5 is associated with anxiety and mood-related problems, and that it can be impacted by stressful external experiences. Reduced expressions of this gene have been linked to PTSD.

There’s also a relationship between FKBP5 and the hippocampus. Expression of FKBP5 can affect secretion of the stress hormone cortisol, which in turn can lead to atrophy in the hippocampus.

Using blood tests, the researchers found that increased expression the FKBP5 gene was also tied to improvement in PTSD.

Conclusions

To summarize, it appears that psychotherapy for PTSD can lead to actual changes in the brain—including increased volume of the hippocampus and changes in gene expression. It also suggests that early treatment for PTSD may be helpful undoing some of the damage.

The point I want to underscore is this: all effective treatments impact brain function.  Whether a treatment is a drug treatment, electroshock, or psychotherapy, they all affect the structure and function of people’s brains. Dressing up a psychotherapy in the language of neuroscience doesn’t make it any more effective or scientific. Any effective treatment changes the brain.

Recognizing Posttraumatic Stress Disorder Awareness Month

Unfortunately, mental struggles are often given scant attention in the media. Many people are surprised to learn that others struggle with the same difficulties. Although posttraumatic stress disorder (PTSD) has been getting more media attention lately because of the recent wars in Afghanistan and Iraq, I was pleased to learn that the secretary for Department of Health and Human Services (HHS) released a statement  recognizing Posttraumatic Stress Disorder Awareness Month. She writes:

During PTSD Awareness Month and on PTSD Awareness Day, June 27, 2012, we focus national attention on this debilitating condition and renew our commitment to support research, education, and treatment for those living with PTSD, as well as for their friends and families.

National recognition and focus on this often debilitating yet treatable problem is a wonderful step in helping people access needed services. I encourage you to read Ms. Sebelius’ statement yourself, and to pass it on to others.
