Navigating the Complex Landscape: Why Borderline Personality Disorder and Bipolar Disorder Often Go Misdiagnosed

Understanding the differences between borderline personality disorder (BPD) and bipolar disorder can be a perplexing challenge, especially given the frequent misdiagnoses that occur between the two. This article explores why distinguished mental health professionals often fail to differentiate between these conditions and the complexities involved in diagnosis. Additionally, it touches on personal insights to better illustrate the nuances between these disorders.

Common Misunderstandings and Challenges in Diagnosis

Diagnosis can be elusive for several reasons, primarily due to overlapping symptoms and the ignorance of many mental health professionals regarding the intricacies of personality disorders. One individual, who has been assessed multiple times and is diagnosed with bipolar disorder, shares their experience and insights.

“I've been assessed more than once as having no sign of a personality disorder but I do have bipolar. My relationships are very stable; I don't threaten suicide; I don't have black and white thinking or issues with abandonment. I am not an impulsive person unless I am hypomanic and I respond very well to bipolar medication. Unless I am in a mood episode, I am just like everyone else. I am traumatized but not in a BPD way,” the individual explains.

Diagnostic Confusion Caused by Misinformation and Limited Knowledge

Modern medical and psychological diagnostic guidelines provide clear criteria for distinguishing between BPD and bipolar disorder. However, the frequent misdiagnosis often stems from the lack of in-depth knowledge among mental health professionals, especially regarding personality disorders.

“I got diagnosed with type 2 bipolar the first session with an old shrink after just one hour of talking. A couple more sessions, and she also diagnosed me with MDD. The 6th or 7th session, I mentioned having BPD. That's the only cluster B PD I knew anything about thanks to an old nurses' textbook I kept for over a decade, and I read it from front to back. As a 20, I read the words ‘antisocial’ and my ignorance said nope, not antisocial, so I ignored it. I read narcissistic, thought of Randy, and said fuck no, Randy is a sperm donor. Histrionic made me a bit uneasy but promptly ignored it too. This was before smartphones, before personality disorders were such a huge interest with fucking everyone. Fast forward to 2016 and I told the lady I thought I had BPD. I had just gone through my first 'real' breakup as in the first person I really loved as much as I could love a person at fucking 27 and was probably presenting at least 7/9… I think if I had been truly borderline, she would have diagnosed me. Instead, she diagnosed me with PD-not otherwise specified (PD-NOS) from the DSM-IV. It can mean that I have traits of many, or that I am definitely disordered but the clinician doesn't know enough to dx me. I am definitely fucking disordered,” the individual elaborates.

The Importance of Thorough Assessment and Continuous Learning

Thoroughness in psychiatric assessments is crucial, as it enhances the likelihood of accurate diagnosis. The nature of psychiatric disorders often requires a combination of psychological and medical evaluations, rather than a one-dimensional approach. Continuous learning and staying updated with the latest research and diagnostic criteria can also significantly reduce the risk of misdiagnosis.

Monica Fried, a renowned psychologist, emphasizes, “Educating ourselves and continually updating our knowledge base is imperative to improving diagnostic accuracy. Not all symptoms are apparent in the first consultation, and patients may benefit from multiple sessions to provide a more nuanced understanding of their condition.”

Strategies for Clearer Differentiation

Maintaining detailed patient records, observing changes over time, and utilizing multiple forms of assessment can aid in distinguishing between BPD and bipolar disorder. Collaboration with other healthcare professionals and sharing information are also valuable strategies.

“Doctors want to diagnose someone the first time they ever see a patient. Bipolar is cyclical – meaning it comes and goes in cycles even if there are times of 'remission'. PDs are always there. It's a deeply ingrained fucked way of thoughts and behaviors that got you through childhood, but they don't work so well in adulthood. Doctors are extremely ignorant in general about personality disorders. So, there’s that too,” the individual concludes.

To summarize, while diagnosing borderline personality disorder and bipolar disorder can be challenging, a thorough, continuous, and patient-centered approach can help improve diagnostic accuracy. It is crucial for healthcare professionals to stay updated and employ strategies that minimize the risks of misdiagnosis.
