Borderline Personality Disorder: Symptoms, Causes & Treatment

Everyone experiences mood changes or relationship difficulties from time to time. However, when emotions become extremely intense or difficult to regulate, or when they significantly affect relationships, self-image, behavior, and everyday life, professional assessment may be needed.

Borderline personality disorder (BPD) is a mental health condition that affects emotional regulation, behavior, self-perception, and relationships with others.

What is borderline personality disorder? What are its most common symptoms and possible causes? How is BPD diagnosed and treated, and can people recover from it? This guide covers the key facts about BPD and explains when seeking professional mental health support may be appropriate.

What Is Borderline Personality Disorder?

Borderline personality disorder (BPD) is a mental health condition characterized by difficulties with emotional regulation that can affect the way a person thinks and feels about themselves and others, as well as their behavior and interpersonal relationships.

People with BPD may experience intense and rapidly changing emotions, sensitivity to rejection or abandonment, difficulties maintaining stable relationships, impulsive behavior, or changes in their sense of identity.

Experiencing mood swings or relationship difficulties alone does not mean that someone has borderline personality disorder. A diagnosis requires a comprehensive professional assessment that considers the nature, duration, pattern, and impact of symptoms across different areas of life.

What Are the Symptoms of Borderline Personality Disorder?

Borderline personality disorder symptoms can vary considerably from one person to another, and not everyone with BPD experiences the same symptoms or level of severity.

Common symptoms and patterns associated with BPD may include:

Intense and rapidly changing emotions: Emotional responses may be particularly strong and can shift significantly in response to certain situations or interactions.
Fear of abandonment or rejection: A person may be highly sensitive to real or perceived rejection or separation.
Unstable interpersonal relationships: Relationships may involve significant changes in how the person perceives or feels about others.
Changes in self-image or identity: A person’s sense of themselves, their goals, or their values may sometimes feel unstable.
Persistent feelings of emptiness: Some people experience recurring or long-lasting feelings of inner emptiness.
Intense anger: Anger may feel difficult to manage or express appropriately.
Impulsive behavior: Some individuals may engage in impulsive or risky behaviors that can have negative consequences.
Self-harm or suicidal thoughts and behaviors: These can occur in some people with BPD and require serious attention and appropriate professional support.
Stress-related symptoms: During periods of severe stress, some people may experience dissociation, feeling disconnected from themselves or their surroundings, or other unusual perceptions.

Having one or more of these symptoms does not establish a BPD diagnosis. Similar symptoms can occur in other mental health conditions, making professional evaluation important.

What Causes Borderline Personality Disorder?

There is no single known cause of borderline personality disorder. Research suggests that BPD may develop through a complex interaction between biological, genetic, psychological, and environmental factors.

Factors that may be associated with an increased likelihood of developing BPD include:

Genetic factors: Some individuals may have an inherited vulnerability to developing the condition.
Brain function and emotional regulation: Differences in processes involved in emotional regulation and responses to stress may play a role.
Difficult childhood experiences: Adverse experiences during childhood may influence emotional and psychological development in some people.
Neglect or abuse: Experiences of neglect or abuse have been associated with increased risk in some cases.
Unstable early or family relationships: Relationship experiences during development may contribute to vulnerability.
Environmental and psychological factors: These may interact with individual biological and psychological characteristics.

Having one or more risk factors does not mean that a person will develop BPD, and the condition should not automatically be attributed to any single experience or event.

How Is Borderline Personality Disorder Diagnosed?

A borderline personality disorder diagnosis should be made by a qualified mental health professional following a comprehensive clinical assessment.

The assessment typically involves discussing the person’s symptoms, how long they have been present, their patterns over time, and how they affect relationships, work, education, and everyday functioning. Relevant medical and mental health history may also be reviewed.

An important part of the assessment is determining whether another mental health condition could better explain some or all of the symptoms. Mood instability, impulsivity, and relationship difficulties, for example, can occur in several different conditions.

Online questionnaires may provide general information, but they should not be used as a substitute for professional diagnosis.

How Is Borderline Personality Disorder Treated?

Borderline personality disorder can be treated, and psychotherapy is a central component of treatment. The specific treatment plan depends on the individual’s symptoms, needs, circumstances, and any co-occurring mental health conditions.

Psychotherapy

Psychotherapy can help people better understand their emotions, thoughts, behaviors, and relationship patterns while developing more effective ways of responding to difficult situations.

Treatment may focus on improving emotional regulation, reducing impulsive or harmful behaviors, developing healthier coping strategies, managing stress, and improving interpersonal relationships.

Dialectical Behavior Therapy (DBT)

Dialectical behavior therapy (DBT) is one of the therapeutic approaches used specifically in the treatment of borderline personality disorder.

DBT focuses on developing practical skills related to emotional regulation, distress tolerance, mindfulness, and interpersonal effectiveness. These skills can help individuals respond more effectively to intense emotions, stressful situations, and relationship difficulties.

Cognitive Behavioral Therapy (CBT)

Elements of cognitive behavioral therapy (CBT) may also be used depending on an individual’s needs and treatment plan.

CBT can help identify unhelpful patterns of thinking and behavior, understand how they influence emotions and actions, and develop more balanced and effective responses.

Medication

Medication is not considered the primary treatment for borderline personality disorder itself. However, a physician may prescribe medication in certain situations to address specific symptoms or co-occurring mental health conditions.

Medication decisions should be made by a qualified healthcare professional based on an individual clinical assessment. Prescribed medication should not be started, stopped, or changed without medical guidance.

Can You Recover from Borderline Personality Disorder?

Yes. Many people with borderline personality disorder can experience significant improvement with appropriate treatment and continued support. Symptoms may become less severe and have less impact on daily life over time.

Treatment is not limited to reducing symptoms. It can also help individuals improve emotional regulation, reduce harmful or impulsive behaviors, build more stable relationships, and improve overall functioning and quality of life.

The length and course of treatment vary from person to person, and progress may not always follow a straight line. Individual experiences should therefore not be compared or expected to follow the same timeline.

Working consistently with a mental health professional experienced in personality disorders can help identify individual needs, monitor progress, and adjust the treatment plan when necessary.
