Overview

  • Borderline Personality Disorder is a serious mental health condition affecting an estimated 1.4% of U.S. adults, characterized by ongoing patterns of turbulent emotions, unstable self-image, impulsive behavior, and relationship problems.
  • It occurs equally in men and women. Symptoms typically emerge during teenage years and early adulthood. Episodes of anger, depression, and anxiety can last from minutes to a few days.
  • BPD is centered on difficulty managing emotions and a tendency to see things in extremes (“all good” or “all bad”). This fundamentally impacts how people with BPD relate to themselves and others.
  • There are four recognized BPD types: Discouraged (Quiet), Impulsive, Self-destructive, and Petulant.
  • It commonly co-occurs with depression, anxiety, eating disorders, and substance abuse. Risk factors include genetics, brain structure differences, and adverse childhood experiences — but risk factors are not the same as causes.
  • BPD has historically been viewed as difficult to treat, but evidence-based treatments (especially DBT and CBT) are proven effective. Many people show significant improvement over time with consistent treatment.

BPD Symptoms

A BPD diagnosis requires at least five of the following. Symptoms can be triggered by ordinary events. 

  • Ongoing feelings of emptiness: Persistent numbness or emptiness that attempts to fill with food, sex, alcohol, or drugs can’t resolve.
  • Fear of abandonment: Intense fear of real or imagined separation or rejection, leading to frantic efforts to avoid it — rapidly initiating relationships or cutting off contact preemptively.
  • Unstable and intense relationships: Extreme, rapid shifts in how others are perceived — adoring someone one moment, finding them cruel the next. 
  • Shifting self-image: Abrupt changes in self-identity, goals, and values; may include seeing oneself as fundamentally bad or non-existent.
  • Mood swings: Intense but short-lived shifts between happiness, irritability, shame, sadness, or anxiety — often lasting hours or minutes rather than days.
  • Risky behavior: Impulsive actions such as drug use, gambling, reckless driving, or sabotaging success.
  • Intense anger: Frequent, extreme rage directed at self or others; may involve screaming, throwing objects, or physical altercations.
  • Dissociation: Feeling cut off from oneself, seeing oneself from outside the body, losing touch with reality, or feeling foggy and spaced out.
  • Self-harm: Threats of self-harm or suicidal thoughts, often in response to fear of separation or perceived rejection.

Types of BPD

  • Discouraged (Quiet) BPD: Frequent shame, guilt, social anxiety, feelings of inadequacy, and obsessive patterns. 
  • Impulsive BPD: Intense need for immediate gratification, discounting delayed rewards, strong feelings of rejection and anger. 
  • Self-destructive BPD: Frequent self-sabotage of relationships and engagement in risky behaviors with little regard for consequences. 
  • Petulant BPD: Inappropriate anger outbursts, unstable self-image, urge to manipulate or control others, difficulty maintaining relationships.

Causes of BPD

The exact cause is unknown. However, research shows BPD occurs equally in men and women. Risk factors are not the same as causes — many people develop BPD without any known risk factors.

  • Genetics: More common in people with a first-degree relative with BPD, though family history doesn’t guarantee development.
  • Brain structure: Physical changes and abnormalities in brain structure or function may increase risk.
  • Environmental factors: Childhood abuse (sexual, physical, or emotional), fear of abandonment in childhood or adolescence, or an unstable family environment.

Treatment for BPD

Evidence-based treatments are proven to help people experience fewer and less severe symptoms. A treatment plan may include therapy, medication, hospitalization, or a combination. 

1. Therapy

  • Dialectical behavior therapy (DBT): Developed specifically for BPD. Uses mindfulness and acceptance to teach skills for controlling intense emotions, reducing self-destructive behavior, and improving relationships.
  • Cognitive behavioral therapy (CBT): Identifies and changes unhealthy beliefs, behaviors, and inaccurate perceptions; helps develop healthier responses to anger, insecurity, and anxiety.
  • Outpatient/inpatient treatment: For severe symptoms. Hospitalization or emergency care may be needed in instances of self-harm.

2. Medication

Medication does not cure BPD but can relieve symptoms. An in-person or online psychiatrist may prescribe antidepressants, antipsychotics, or anti-anxiety medications. Always used alongside therapy, not as a standalone treatment. 

3. Alternative & Natural Treatments

Holistic and natural remedies are increasingly used alongside therapy to manage BPD symptoms. 

Conditions Similar to BPD

Many people with BPD also have signs of at least one additional condition. Symptoms can appear similar across conditions, but each has distinguishable differences and its own treatment approach.

Other Personality Disorders

  • Cluster A: Odd or eccentric thinking/behavior: paranoid, schizoid, and schizotypal personality disorders.
  • Cluster B: Dramatic, emotional, or unpredictable behavior: antisocial, BPD, histrionic, and narcissistic personality disorders.
  • Cluster C: Anxious or fearful thinking: avoidant, dependent, and obsessive-compulsive personality disorders.

Depression

Depression: A mood disorder causing persistent sadness, loss, or anger that severely impacts quality of life. Affects ~8.1% of U.S. adults and commonly co-occurs with BPD.

Anxiety Disorders

Anxiety disorders: Feelings of fear or apprehension that last longer than six months and impair daily life. Can co-occur with BPD.

Bipolar Disorder

Bipolar disorder shares some similarities with BPD — both involve extreme emotions and impulsive behavior — but they are distinct conditions with different treatment approaches. See: Borderline Personality Disorder vs. Bipolar Disorder.

PTSD

PTSD is triggered by traumatic events and can involve severe anxiety and intrusive thoughts. PTSD symptoms overlap with BPD, complicating diagnosis.

ADHD

ADHD: Ongoing inattention and impulsive hyperactivity that can negatively affect daily functioning. Shares some behavioral overlap with BPD.

Types of BPD

While continued research indicates the likelihood of even more subcategories for the various BPD types, there are generally four types recognized today.

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.

Discouraged Borderline Personality Disorder (Quiet BPD)

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.

What are the common signs of BPD?

The most recognizable signs are intense fear of abandonment, extreme and rapid shifts in how others are perceived (idealization to devaluation), emotional mood swings that come on quickly and intensely, impulsive or risky behavior, persistent feelings of emptiness, and episodes of anger, dissociation, or self-harm. Symptoms typically first appear in the teen years or early adulthood and must meet a threshold of at least five criteria for a formal diagnosis.

How do you get diagnosed with BPD?

Diagnosis is made by a licensed professional through thorough BPD screening questions about current symptoms and emotional state. You can begin by speaking with your primary care doctor for a referral, taking a BPD assessment, or connecting with a therapist via online therapy. A formal diagnosis requires at least five of the nine recognized BPD symptoms, and the clinician will rule out other conditions with similar presentations.

Who can diagnose BPD?

Psychiatrists, psychologists, and licensed clinical therapists are qualified to diagnose BPD. A primary care physician can be a useful starting point and can provide a referral to a mental health specialist. Only a licensed professional can make an official diagnosis.

Can an online therapist diagnose BPD?

Yes. Licensed therapists and psychiatrists practicing via telehealth platforms can conduct BPD evaluations and make a diagnosis. Online therapy is also an accessible and effective option for ongoing treatment, including DBT and CBT. An online psychiatrist can also support medication management if needed.

What type of therapy is best for BPD?

Dialectical behavior therapy (DBT) (https://www.talkspace.com/blog/dialectical-behavioral-therapy-dbt-behavior/) is the most evidence-based therapy developed specifically for BPD. It uses mindfulness and acceptance to teach emotional regulation, distress tolerance, interpersonal effectiveness, and self-awareness. CBT is also widely used and effective. The two are often combined. Inpatient or intensive outpatient treatment may also be recommended for more severe presentations.

When should you seek professional help for BPD?

Seek help if patterns of intense emotional swings, fear of abandonment, unstable relationships, impulsive behavior, or self-harm are recurring and disrupting your daily life, work, or relationships. If you are experiencing suicidal thoughts or urges to self-harm, seek help immediately. BPD does not improve on its own — professional treatment is essential. The sooner you begin, the better the long-term outlook.

Can BPD be treated?

Yes. While BPD has historically been considered difficult to treat, evidence-based treatments — especially DBT — are proven to help people experience fewer and less severe symptoms. Many people with BPD show significant improvement over time. Consistent engagement with therapy, and medication where appropriate, leads to meaningful increases in stability and quality of life.

What therapy methods are used for borderline personality disorder?

The two most evidence-based approaches are DBT (developed for BPD; teaches emotional regulation, distress tolerance, and interpersonal skills using mindfulness and acceptance) and CBT (identifies and changes unhealthy beliefs and behaviors; builds healthier responses to anger, insecurity, and anxiety). Inpatient or intensive outpatient treatment is also used for severe symptoms.

What are conditions similar to BPD?

Conditions commonly related to or confused with BPD include other personality disorders (Cluster A, B, and C), depression, anxiety disorders, bipolar disorder (see: BPD vs. Bipolar Disorder), PTSD, and ADHD. Each has overlapping features with BPD but distinct differences. A comprehensive evaluation by a licensed professional is needed to distinguish between them.

How can I get help for BPD?

Start by speaking with your primary care doctor for a referral, taking a BPD assessment, or connecting with a therapist through online therapy. The key is to seek professional help as early as possible and commit to the treatment plan. Over time, a combination of therapy, medication when needed, and an overall healthy lifestyle leads to increased stability and quality of life.
