Borderline personality disorder (BPD) is a mental health condition that significantly impacts an individual’s thoughts, emotions, and behavior, leading to challenges in daily functioning. People with BPD often struggle with self-image, emotion regulation, and maintaining stable relationships.

Individuals with BPD experience an intense fear of abandonment or instability, making it difficult for them to tolerate being alone. However, their impulsiveness, inappropriate anger, and frequent mood swings can push others away, despite their desire for loving and lasting relationships.

BPD typically emerges in early adulthood and may worsen during young adulthood, but it can improve gradually with age.

Symptoms of Borderline Personality Disorder

BPD affects how individuals feel about themselves, their relationships with others, and their behavior. Common signs and symptoms include:

  • An intense fear of abandonment, leading to extreme measures to avoid separation or rejection, real or imagined.
  • A pattern of unstable, intense relationships, characterized by idealization of others one moment and then sudden beliefs that the person doesn’t care enough or is cruel.
  • Rapid changes in self-identity and self-image, including shifting goals and values and feeling as if one is inherently bad or non-existent.
  • Episodes of stress-related paranoia and loss of contact with reality, lasting from minutes to hours.
  • Engaging in impulsive and risky behaviors, such as gambling, reckless driving, unsafe sex, binge eating, drug abuse, or sabotaging successful relationships or jobs.
  • Displaying suicidal threats, self-injury, or self-harming behavior in response to fears of separation or rejection.
  • Experiencing wide mood swings lasting hours to days, with intense happiness, irritability, shame, or anxiety.
  • Feeling a chronic sense of emptiness.
  • Expressing inappropriate, intense anger, frequently losing temper, being sarcastic or bitter, or engaging in physical fights.

When to Seek Professional Help

If you recognize any of the signs or symptoms of BPD in yourself, it’s essential to talk to your doctor or a mental health provider.

If you have suicidal thoughts: Seek help immediately by:

  • Calling 911 or your local emergency number.
  • Contacting a suicide hotline, such as the 988 Suicide & Crisis Lifeline in the U.S. (call or text 988) or using the Lifeline Chat.
  • Reaching out to your mental health provider, doctor, or other healthcare professional.
  • Contacting a loved one, close friend, trusted peer, co-worker, or someone from your faith community.

If you notice signs or symptoms in a family member or friend, encourage them to see a doctor or mental health provider. However, remember that you can’t force someone to seek help, and seeking therapy for yourself can be helpful if dealing with stress from the relationship.

Causes of Borderline Personality Disorder

The exact causes of BPD are not fully understood. It may be linked to:

  • Genetics: Some studies suggest a hereditary predisposition, with personality disorders possibly inherited or strongly associated with other mental health disorders in family members.
  • Brain abnormalities: Research has shown changes in certain brain areas involved in emotion regulation, impulsivity, and aggression. Additionally, brain chemicals like serotonin, responsible for mood regulation, may not function correctly.

Risk Factors

Several factors related to personality development may increase the risk of developing BPD:

  • Hereditary predisposition: A higher risk may be present if a close relative, such as a parent or sibling, has the same or a similar disorder.
  • Stressful childhood: Many individuals with BPD report a history of sexual or physical abuse, neglect, or separation from a caregiver. Exposure to hostile conflict and unstable family relationships may also contribute to the development of BPD.


BPD can have significant negative effects on various aspects of life, leading to complications such as:

  • Repeated job changes or losses
  • Incomplete education
  • Legal issues and jail time
  • Conflict-filled relationships, marital stress, or divorce
  • Self-injury, frequent hospitalizations, and involvement in abusive relationships
  • Engaging in impulsive and risky behaviors leading to unplanned pregnancies, sexually transmitted infections, motor vehicle accidents, and physical fights
  • Increased risk of other mental health disorders, such as depression, substance misuse, anxiety disorders, eating disorders, bipolar disorder, PTSD, ADHD, or other personality disorders

It’s important to remember that with proper treatment and support, many individuals with BPD can experience improvement over time and lead fulfilling lives.

For any concerns or questions related to borderline personality disorder, it is advisable to seek professional guidance from healthcare providers or mental health professionals.

Borderline personality disorder and other personality disorders are diagnosed through a comprehensive assessment process, which includes:

  • Detailed interview with your doctor or mental health provider
  • Psychological evaluation, possibly involving questionnaires
  • Review of medical history and physical examination
  • Discussion of signs and symptoms

A diagnosis of borderline personality disorder is typically made in adults, as signs and symptoms may change as children mature. Early diagnosis and intervention are essential to improve outcomes.


Borderline personality disorder is primarily treated with psychotherapy, and medication may be prescribed in combination. In some cases, hospitalization may be necessary to ensure safety.

Effective treatment can provide you with coping skills and strategies to manage your condition. It is also crucial to address any co-occurring mental health disorders, such as depression or substance misuse, that often accompany borderline personality disorder. With proper treatment, you can experience a more stable and fulfilling life.


Psychotherapy, also known as talk therapy, is a fundamental treatment approach for borderline personality disorder. Your therapist will tailor the therapy type to suit your needs. The goals of psychotherapy include:

  • Improving your ability to function in daily life
  • Learning to manage uncomfortable emotions
  • Reducing impulsiveness by observing feelings instead of acting on them
  • Enhancing relationships by understanding your emotions and those of others
  • Gaining insight into borderline personality disorder

Effective types of psychotherapy for borderline personality disorder include:

  • Dialectical behavior therapy (DBT): Combines group and individual therapy to teach emotion regulation, distress tolerance, and improved relationships.
  • Schema-focused therapy: Focuses on identifying unmet needs that contribute to negative life patterns and helps establish healthier ways to meet those needs.
  • Mentalization-based therapy (MBT): Helps you recognize your thoughts and feelings and develop alternative perspectives.
  • Systems training for emotional predictability and problem-solving (STEPPS): Incorporates family members, caregivers, or friends into group therapy sessions.
  • Transference-focused psychotherapy (TFP): Aims to understand emotions and interpersonal difficulties through the therapeutic relationship.
  • Good psychiatric management: Anchors treatment in work or school participation and considers the interpersonal context for emotions.


No medications are specifically approved for treating borderline personality disorder, but certain drugs may help manage symptoms or co-occurring issues like depression, impulsivity, aggression, or anxiety. Antidepressants, antipsychotics, or mood stabilizers may be prescribed, and it’s essential to discuss the benefits and potential side effects with your doctor.


In some cases, more intensive treatment in a psychiatric hospital or clinic may be necessary, especially if there’s a risk of self-injury or suicidal thoughts.

Recovery takes time

Managing emotions, thoughts, and behaviors requires patience and time. While most individuals with borderline personality disorder experience significant improvement, some symptoms may persist. However, with treatment, functioning can improve, and overall well-being can be enhanced. Seek help from a mental health provider experienced in treating borderline personality disorder for the best chance of success.

Coping and Support

Coping with borderline personality disorder can be challenging for both you and those around you. Alongside professional treatment, consider these strategies:

  • Learn about the disorder to better understand its causes and treatments
  • Recognize triggers for anger or impulsive behavior
  • Adhere to your treatment plan, attending therapy sessions and taking medications as prescribed
  • Develop a crisis plan with your mental health provider
  • Address related issues like substance misuse
  • Involve supportive individuals in your treatment
  • Practice coping skills, such as breathing techniques and mindfulness meditation, to manage intense emotions
  • Set emotional boundaries to maintain stable relationships
  • Avoid making assumptions about others’ thoughts or feelings about you
  • Connect with others who share the disorder to share experiences and insights
  • Build a supportive network of understanding and respectful individuals
  • Maintain a healthy lifestyle through diet, physical activity, and social engagement
  • Acknowledge your responsibility to seek treatment without blaming yourself for the disorder

Preparing for Your Appointment
