Individuals with borderline personality disorder (BPD) often suffer from strong emotions that change rapidly, from one extreme to another. They may fear abandonment and experience an inner emptiness. They may also behave impulsively and have suicidal thoughts or behaviors. BPD is often mis- or underdiagnosed and there is a tendency among clinicians to avoid the diagnosis.

Given the diagnostic complexity of BPD, it is important to establish a diagnosis. Recent therapeutic advances show that the disorder responds to treatment and that significant recovery is possible. Because mental health services prioritize major psychiatric disorders, such as psychotic disorders and mood disorders, individuals with BPD have significant unmet needs. The suicide rate for BPD is as high as 10%, mirroring that of schizophrenia, and the enduring impairments from the disorder are comparable to those of chronic mental illnesses.

Clinical decision-making regarding diagnosis can be challenging for healthcare professionals for several reasons and is surrounded by ethical challenges. Several studies have shown that stigmatization and negative attitudes regarding the diagnosis of BPD are still common. Healthcare professionals, including emergency room staff and multidisciplinary teams, have been surveyed. Results suggest that even specialized mental health professionals have more negative attitudes toward BPD patients than toward those with other diagnoses, such as depression. This is likely due to factors associated with the diagnosis itself, but it is also probably related to clinicians’ perceptions of BPD symptoms and their previous treatment experiences.

Stigmatization is also reinforced by research. Derogatory terms and attitudes regarding BPD are pervasive in academic work on the disorder. A particularly common example is the attribution of negative intentions to individuals with BPD, such as wearing provocative clothing to attract attention or seeking attention by choosing, for example, artistic careers. Yet, we are not aware of any empirical documentation suggesting that BPD is associated with clothing or with specific intentions regarding career choices.

Additionally, many healthcare professionals do not consider BPD to be a genuine diagnosis and believe it to be self-induced or self-diagnosed. Consequently, individuals with BPD are often not informed about their disorder or are told that they have another diagnosis, such as bipolar disorder, compromising the principle of transparent diagnosis and patient empowerment for informed and consensual care.

The diagnosis of personality disorder is sometimes used as a label for disliked individuals. This is hardly surprising, given that interpersonal relationship problems are the primary characteristic of these disorders. However, we cannot ignore the fact that personality issues are extremely common, and rejection based on perceived undesirability is not acceptable. We now have evidence from around the world that personality disorders occur in 6 to 12% of the population, with a much higher prevalence among psychiatric patients. Of course, these figures may prompt accusations of inappropriate medicalization of normal human variations, but this criticism must be questioned. Recent findings have shown that even relatively mild personality disorders are associated with greater psychopathology, higher use of health services, and higher costs compared to individuals without personality pathology, and this is an increasing trend.

In a new article, I challenge existing perspectives and discourses about the clinical reality of the disorder. I compared impulsivity, anxiety, hopelessness, suicidal tendencies and depression in BPD patients and the general population during the COVID-19 isolation in France. While all groups exhibited elevated levels of impulsivity and anxiety, statistically significant differences were found in the severity of hopelessness, suicidal ideation, anxiety, and depression. Specifically, individuals with BPD showed markedly higher levels of these symptoms compared to the general population sample. This suggests that BPD exhibits a distinct profile of chronic distress, exceeding the levels seen in general stress reactions or other disorders like depression or anxiety that are more recognized and accepted in society.

My own and similar studies suggest that there is a need for a critical reevaluation of the diagnostic methods for personality disorders such as BPD. There is growing concern that some healthcare professionals may underdiagnose personality disorders, possibly because such disorders are not perceived to be severe. This reluctance to diagnose, combined with inadequate training in diagnostic procedures, may contribute to a systemic failure to recognize and address the prevalence and impact of personality disorders. The healthcare system then risks perpetuating the misconception that diagnostic and communication challenges related to personality disorders are not significant.

Better diagnostic practices, coupled with more accurate case descriptions and better treatment planning, can ensure faster and more effective treatment. This would provide individuals with the opportunity for personal and clinical recovery. Furthermore, the process of communicating the diagnosis of BPD is fundamental to how people understand and interpret their diagnosis, which in turn can affect their hope for recovery and motivation to use healthcare services. In conclusion, there is room for significant improvement in how we approach personality disorders such as borderline personality disorder.
