Why Borderline Personality Disorder is Misdiagnosed

By Alan E. Fruzzetti, Ph.D. | Oct. 03, 2017

 

Living with Borderline Personality Disorder (BPD) is difficult for many reasons, including unstable relationships, emotional reactivity and dysregulation, impulsivity, and other challenging features. But what makes the condition even harder is that many people who live with Borderline Personality Disorder don’t even know they have it.

BPD is one of the most commonly misdiagnosed mental health conditions. It’s so misdiagnosed, in fact, that there isn’t even an accurate prevalence rate for the condition. What we do have is an estimate of 2–6% of the population, which actually makes BPD very prevalent. So how is it possible that a prevalent condition is so misdiagnosed? Here are just a few reasons why that could be.

Stigma in Society and Among Professionals

BPD is one of the most heavily stigmatized mental health conditions a person can experience. This rampant stigma has both tangible and emotional consequences that can worsen existing difficulties with BPD. In the form of judgments, blame, negative assumptions and discrimination, stigma can lead a person experiencing BPD to feel ashamed and hide their suffering. This leads to further negative emotion (shame, loneliness, fear) and attempts to suppress distress. Suppression of distress and self-invalidation typically results in further emotion dysregulation, dysregulated thinking and out-of-control behavior.

Even if individuals are determined enough to push through the stigma and seek treatment, they may encounter even more stigma. Some mental health professionals are reluctant, or even refuse, to diagnose and/or treat BPD even when a person clearly meets diagnostic criteria.

The Myth That Teens Can’t Have BPD

This problem is even more pronounced among adolescents: Many clinicians fear that even correctly diagnosing a teenager with BPD will only worsen their problems because of stigma. In addition, many professionals incorrectly believe that it is not possible to diagnose BPD in adolescents. This results in underdiagnoses and inaccurate prevalence rates. Worst of all: It prohibits teens from receiving the specialty care they need when early detection and early intervention are essential to recovery.

BPD Looks Like So Many Other Mental Health Conditions

People with BPD typically also meet the criteria for multiple other diagnoses, including depression, anxiety, post-traumatic stress disorder, substance use disorders, eating disorders, bipolar disorder, and so on. These disorders, of course, are not independent of BPD, but are connected and related through shared psychological, social and biological pathways. However, when these other diagnoses are the focus of treatment, they can dominate professionals’ attention, preventing any significant focus on the whole pattern of difficulties, resulting in missed diagnosis of BPD.

In particular, there is evidence that BPD is commonly misdiagnosed as Bipolar Disorder, Type 2. One study showed that 40% of people who met criteria for BPD but not for bipolar disorder were nevertheless misdiagnosed with Bipolar Type 2. This is most likely due to some similarities between symptoms: impulsive behavior, intense emotions and suicidal thinking. However, they are very different diagnoses with different treatments methods, so it’s crucial for mental health professionals to understand and know the difference.

The Myth that BPD Isn’t Treatable

Some of the problems with diagnosing result from the fact that there was no evidence of effective treatment for BPD until the 1990s. The first published evidence for the effectiveness of Dialectical Behavior Therapy was by Marsha Linehan in 1991. Before then, many clinicians blamed people with BPD for not getting better, rather than acknowledging that professionals had not yet figured out how to treat people with BPD successfully, or trying to find more effective pathways for treatment. Today, unfortunately, many professionals continue to think that BPD is not treatable despite growing evidence that it is. This leads some professionals to avoid giving the diagnosis even when someone meets the criteria.

But Only Women Can Have BPD, Right?

Gender is another factor in misdiagnosis. The epidemiological rates of BPD in males and females are roughly equal. However, females are over-diagnosed and males are underdiagnosed significantly. This happens in part because women are overrepresented in most studies and treatment. Stereotypes about masculinity and femininity are also likely at play. It’s no surprise that females, who have long been stereotyped for being “emotional” or “hysterical,” are the ones who are over-diagnosed.

Of course, there are many other factors that influence the accuracy (or inaccuracy) of a BPD diagnosis. However, the more individuals with BPD and their families become aware of these problems, the more they can advocate for accuracy. A lack of understanding about BPD already prevents people from seeking treatment. So, for those who do seek help, we should make sure they are getting the proper treatment. And that starts with getting the correct diagnosis.

What distinguishes a psychobble term from accepted jargon in a theory that will likely be discarded in 25 years, forgotten in 50 and unheard of in a century? The presumption of prefacing "regulation" with the unnecessary "dys" makes one disinclined even to question what such a word means. Respect ordinary speech.

Giving labels to different “mental illnesses” should stop (not just for BPD, but for all “mental illnesses”). This is because despite decades of research, scientists have not been able to find any structural or other brain differences between patients with mental conditions and healthy individuals (this is why there are no objective tests to detect them). Labels increase stigma and also disempower people.

My son is currently hospitalized for the third time. I've given doctors information that strongly leads me to believe he has BPD, he get diagnosed with other illnesses--depression, anxiety, psychosis, and now possibly schizophrenia. Mental health professionals don't seem to give BPD enough attention; it is so frustrating!

Thank you. Thank you for verbalizing this to a large audience. I have heard so many shaming and hurtful comments within the counseling profession directed toward people with BPD. I myself am working toward getting my master’s degree in Mental Health Counseling and hear such misguided opinions about this diagnosis. No one I’ve worked with, however, realizes that I am currently diagnosed with this disorder and going through treatment. Their comments are so hurtful and make me feel like such a terrible person for something I did not ask for any can’t simply control. So thank you. Thank you for speaking up when I haven’t yet found my voice to do the same.
