The Relationship Between PTSD and Trichotillomania

People with post-traumatic stress disorder (PTSD) have been found to be at high risk for engaging in a number of unhealthy and self-destructive behaviors; however, one behavior that has been examined less frequently is trichotillomania.

What Is Trichotillomania?

Trichotillomania is an impulse control disorder that is made up of the following symptoms:

  • Recurrent pulling out of one's hair eventually results in some noticeable hair loss.
  • Repeated attempts are made to stop hair pulling or do it less often.
  • Clinically significant feelings of distress or social impairment are caused by hair pulling.
  • Hair pulling or hair loss isn't caused by another medical condition,
  • It isn't the symptom of another mental disorder.

In addition, to be diagnosed with trichotillomania, the symptoms described above cannot be better accounted for by some other disorder or a health condition. Also, the symptoms have to result in distress or impairment in different domains of a person's life.

Little is known about trichotillomania, but some research indicates that it occurs among 0.5% to 2% of the general population. However, there is some evidence to suggest that people with certain mental health disorders, including anxiety disorders such as PTSD, may be more likely to engage in this behavior.

PTSD and Trichotillomania

To examine the connection between traumatic exposure, PTSD, and trichotillomania, researchers conducted a study among a group of patients seeking treatment at a trichotillomania clinic. The researchers asked these participants about their past traumatic exposure and assessed symptoms of PTSD.

They found that about 76% of the patients said that they had experienced at least one traumatic event in their lifetime. In addition, 19% met the criteria for a diagnosis of PTSD. Notably, this rate of PTSD is much higher than found in the general population.

Interestingly, the researchers also found that the severity of a patient's trichotillomania was associated with less severe PTSD symptoms. According to the authors of this study, this might suggest that trichotillomania is being used to reduce stress, anxiety, and tension associated with the experience of PTSD symptoms.

Although PTSD symptoms were less severe among those with more severe trichotillomania, this doesn't necessarily mean that this behavior "works" to address PTSD symptoms. As with other self-destructive behaviors, although trichotillomania may bring about some initial reduction in distress, it doesn't allow someone to adequately process their emotions.

Not surprisingly, other studies have found that trichotillomania is related to emotional avoidance. Consequently, these emotions may eventually come back and may come back stronger. In addition, the shame that people with trichotillomania may feel as a result of losing their hair may also eventually increase distress and make some PTSD symptoms worse (for example, feeling distant from others or isolation).

Getting Help

If you suffer from PTSD and trichotillomania, it is important that you seek help. There are a number of effective treatments available for PTSD, and successful completion of these treatments may improve your response to treatments for trichotillomania or reduce the need to engage in behaviors such as trichotillomania. For example, habit reversal and other cognitive-behavioral interventions have been found to be helpful for people with trichotillomania.

Certain medications also have support in the treatment of trichotillomania. In addition, some studies have shown that Acceptance and Commitment Therapy may be particularly helpful for people with trichotillomania.
