Borderline personality disorder (BPD) is a mental health condition (personality disorder) that affects roughly 1.6% of the population. BPD can be difficult to diagnose because not all symptoms appear with every diagnosis. Adding to the challenge, there are several subcategories of BPD, and some symptoms can overlap with each other and with other mental health conditions (like bipolar disorder, depression, and certain eating disorders).
BPD can be classified into four distinct types: discouraged, impulsive, petulant, and self-destructive BPD. Each type shares specific characteristics but also has its own symptoms, challenges, and optimal treatment techniques. It is possible to experience more than one type simultaneously or at different stages in life. Some individuals with BPD may also not exactly fit into any of these categories.
In this article, we’ll explore each of the four main types of BPD in-depth and discuss how to treat them.
While continued research indicates the likelihood of even more subcategories for the various BPD types, here we’re focusing on the four borderline personality disorder types characterized by Theodore Millon’s research.
“Learning the signs and symptoms of borderline personality disorder can feel both overwhelming and empowering – knowing what you need to best support, like the right therapist and psychiatrist, can be incredibly beneficial to your health and your life. You deserve support!”

Theodore Millon described discouraged borderline personality disorder (also known as quiet BPD ) as being marked by frequent feelings of shame, guilt, emotional attachments, social anxiety, feelings of inadequacy, and obsessions.
Impulsive behavior is a common trait in BPD in general, but it’s prevalent enough in some people to be considered one of the four types of BPD addressed by Millon. Those with impulsive borderline personality disorder have an intense need for immediate gratification and often discount delayed rewards. They tend to experience intense emotions of rejection and anger.
People with petulant BPD can display outbursts of anger that aren’t appropriate for a given situation. They might have an unstable self-image accompanied by feelings of being unloved. They feel a strong urge to manipulate or control others and tend to become possessive, resulting in difficulty maintaining interpersonal relationships. Overall, they’re likely to lack emotional stability.
These BPD types can be their own worst enemies. People with self-destructive borderline personality disorder frequently self-sabotage interpersonal relationships with family members and friends. They might engage in dangerous or risky behaviors, and generally have little regard for the consequences of their actions.
The different types of BPD use slightly different treatment modalities, which can include a combination of medications for specific BPD symptoms combined with various modalities of talk therapy.
Research suggests that each of the four types of borderline personality disorder seems to reflect biologically determined temperaments that could be linked to neuro-biologically based predispositions and vulnerabilities. While we don’t fully understand what causes borderline personality disorder, we are learning more every day about how to treat borderline personality disorder. Some people want to know how to treat BPD naturally,so treatment can vary not only depending on the type of BPD someone has, but also on their personal treatment plan.
Borderline personality disorder is not necessarily treatable with medication. That is, no medication has been discovered that can cure the mental health condition itself. However, people diagnosed with the various types of BPD can be prescribed medication to help them manage symptoms, like anxiety and mood swings, that stem from BPD. BPD medication can also be effective in decreasing the likelihood of self-harm and may help prevent suicidal thoughts.
“If you or someone you care about might be experiencing symptoms of borderline personality disorder, consult with a therapist who specializes in this so you can get the best evaluation and treatment recommendations.”

Psychotherapy is the predominant treatment modality for treating discouraged BPD types. Dialectical behavioral therapy (DBT), cognitive behavioral therapy (CBT), and mentalization-based therapy have all been found effective therapy. Therapeutic interventions like antidepressant medications might be recommended if comorbidity with depression presents.
Impulsive BPD types can be effectively treated with cognitive behavioral therapy and dialectical behavior therapy (DBT).
Therapy is also recommended to treat petulant BPD. Dialectical behavior therapy is the most recommended form of BPD therapy and can teach things like emotion regulation and distress tolerance. It can also help with interpersonal skills. Other forms of therapy that are known to be effective include cognitive behavioral therapy (CBT), mentalization-based therapy, and psychodynamic therapy.
Dialectical behavioral therapy and another form of therapy that uses elements of CBT, known as schema-focused therapy, have been found effective in treating self-destructive BPD. Therapy can help identify triggers, which makes a huge difference in learning to manage any type of mental health condition, including self-destructive BPD. Medication is also commonly recommended.
Self-diagnosis is never recommended to diagnose any of the borderline personality disorder types. Unfortunately, there isn’t any one single test that can accurately determine if someone has BPD, let alone which type they may have. Thorough testing by a qualified mental health professional is the only reliable method of diagnosis. As noted, making a BPD diagnosis can be difficult given the possibly overlapping nature of symptoms. If you want to learn more about your BPD symptoms you can even take a BPD test as a first step. However, be sure to seek in-person or online therapy to get a proper diagnosis.
Identifying types of BPD can involve using a variety of testing and assessment measures, including the Personality Assessment Inventory (PAI) and the American Psychiatric Association’s (APA’s) Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5). The DSM-5 offers a detailed list of criteria used to identify traits and symptoms that must be present in order to make an accurate diagnosis. Also included in the diagnostic process can be health assessments and interviews.
While there’s no clinical recognition in terms of diagnosing each individual BPD subtype, narrowing them down can help a mental health professional decide on the most effective treatment plan, which can be essential is overall BPD treatment success. Zeroing in on the precise types of BPD that need attention is the best way to gauge the most effective treatment modalities.
Using Millon’s BPD subtype concepts has the potential to help people living with borderline personality disorder figure out the most important areas of concern. Then, they can quickly focus on the most needed, most effective type of treatment. New investigations into the subtypes of BPD, as outlined by Millon, continue with the goal of finding better BPD treatment solutions for optimal care and possibly, one day, a cure.
