Histrionic Personality Disorder

While you can’t diagnose someone with histrionic personality disorder yourself — only a psychologist, psychiatrist, or MD can do that — it can be helpful to know what to look for in case you may be able to encourage this person to seek treatment.

It’s estimated that about 2% of the population has histrionic personality disorder. The disorder seems to be more prevalent in women than men, although that may be because women are more likely to show overt symptoms such as flirting or wearing attention-grabbing clothing, and are also more likely to seek treatment for the disorder.

Histrionic personality disorder is one of ten personality disorders recognized by psychiatrists. It’s considered one of the “Cluster B” personality disorders, which also includes narcissistic personality disorder, borderline personality disorder, and antisocial personality disorder. These personality disorders are particularly difficult to treat, and are often described as “dramatic,” “volatile,” or “erratic.”

The DSM-5 lists specific criteria to diagnose histrionic personality disorder. Five of the criteria listed need to be met for a person to be diagnosed.

1. Does not feel like themselves if they are not the center of attention
2. Displays dramatic or provocative behavior
3. A rollercoaster of emotions, often exhibiting “shallow” emotions
4. Highly focused on physical appearance and uses physical appearance to garner attention
5. Vague and imprecise speech patterns
6. Overly dramatic and highly exaggerated emotions
7. Gullible, highly suggestible
8. Has an unrealistic concept of their intimate relationships; may think their relationships are more close-knit than they actually are

Like other personality disorders, histrionic personality disorder isn’t caused by one thing only, but rather a “perfect storm” of factors. Psychiatrists believe that most cases of the disorder occur as a result of a combination of genetic and environmental factors.

Childhood trauma

Childhood trauma is one potential cause of the disorder. It’s hypothesized that some children deal with childhood trauma by exhibiting behaviors common to histrionic personality disorder. What started out as a way to adapt to trauma becomes a full-fledged disorder if not addressed early on.

Parenting styles and genetics

The way a child is parented may also contribute to the disorder. Parents who do not provide appropriate boundaries, who are inconsistent, and who show over-indulgent tendencies may predispose certain vulnerable children to the disorder. Parents who exhibit traits of the disorder themselves, such as dramatic tendencies or abnormal sexual behavior, also may prompt the disorder in their children.

Finally, genetics may be at play. Histrionic personality disorder tends to run in families. Being part of a family with a history is psychiatric disorders, including other personality disorders or substance abuse disorders, may increase a person’s risk of developing histrionic personality disorder.
