Understanding BPD: Symptoms, Causes & Treatment

Borderline Personality Disorder (BPD) is a complex, long-term mental health condition that is defined by unstable emotions, difficult relationships and an overwhelming fear of being abandoned. Although life with BPD can feel daunting and overwhelming to say the least, individuals with BPD can manage symptoms and lead a fulfiling life via proper therapy and support.

This comprehensive guide aims to look at what BPD is, what its symptoms are, what may cause it and discuss effective treatments for BPD, which can improve quality of life and mental wellbeing.

What is BPD?

Borderline Personality Disorder (BPD) is a mental health condition which affects (American Psychiatric Association, 2013) how individuals affected by it view themselves, their relationships with others, and their behavior.

DBT is a therapeutic approach designed specifically for individuals struggling with interpersonal issues related to emotional dysregulation, impulsive behavior, and intense mood swings, which are commonly experienced by individuals diagnosed with BPD.

Borderline personality disorder is one of several acknowledged personality disorders, which are characterised by emotional, thought and behavioural patterns which are inconsistent with cultural norms, lead to distress, and/or impair day-to-day functioning.

Though diagnosed more commonly in women than in men (NICE, 2019), BPD can affect individuals regardless of their gender identity, and usually appears in adolescence or early adulthood.

Common Symptoms of BPD:

Borderline personality disorder symptoms can vary, but the most common psychological signs include:

Emotional dysregulation (Linehan, 1993); difficulty controlling emotions, leading consequently to strong, prolonged emotional responses to minor triggers.
Fear of abandonment (Bateman and Fonagy, 2004); constant fear of abandonment and rejection, often exhibited as clingy (or conversely, avoidant) behavior.
Ineffectual relationships (Lieb et al., 2004); alternating between idealising and devaluing important people in your life, thereby leading to turbulent relationships.
Impulsive behaviours – Taking part in risky behaviours such as overspending, substance abuse, reckless driving, and/or binge eating
Distorted self-image – This can create problems with self-image; thereby, feelings of insecurity or lack of direction.
Self-harm and suicidal tendencies – The use of self-injury, or suicidal thoughts, as a coping mechanism for emotional pain.
Rapid mood changes – Significant mood shifts in a matter of hours or days, which can affect relationships and judgment.
Chronic emptiness – Persistent feelings of emptiness or discontent with life.
Paranoia, or disassociation (American Psychiatric Association, 2013); paranoia, or a sense of disconnection from reality, related to stress.

Recognising these symptoms early is thus crucial for seeking timely support, including the development of an effective treatment plan to promote mental wellbeing.

What Causes BPD?

The causes of borderline personality disorder are multifaceted and involve a combination of genetic, environmental, and neurological factors.

Brain structure and neurochemistry – Differences in the regions of the brain responsible for emotional regulation and impulse control, such as the amygdala and prefrontal cortex, might play a role in the etiology of BPD.
Environmental factors – Experiencing traumatic events, such as childhood abuse, neglect, or unstable family relationships may increase the risk of developing BPD.
Psychological factors – Individuals who are more sensitive to stress or emotional stimuli could be at a higher risk for developing BPD.
Genetic Predisposition – Members of families in which one or more individuals have BPD or other personality disorders are at a higher risk of developing BPD themselves, indicating a potential hereditary link (NICE, 2019). However, genetics alone do not solely determine the likelihood of developing BPD.

Understanding these root causes helps in personalising treatment approaches for individuals with BPD, promoting long-term recovery.

How is BPD Diagnosed?

Diagnosing borderline personality disorder involves a comprehensive assessment by a licensed mental health professional. The process typically includes:

Clinical interviews, where symptoms, triggers, and corresponding behavioral patterns are discussed.
DSM-5 diagnostic criterion review (American Psychiatric Association, 2013) which determines symptomatology utilising the DSM-5 criteria for BPD.
Mental health history assessment, reviewing family and personal history to exclude concurrent conditions such as bipolar disorder and anxiety disorders.

Accurate diagnosis of BPD and/or other personality disorders is thus crucial in tailoring an effective, personalised treatment plan for the personality disorder(s).

Treatment Options for BPD

Although there is no single cure, or treatment, for borderline personality disorder, several evidence-based treatments can significantly improve emotional regulation and quality of life for individuals with BPD:

Cognitive behaviour therapy (CBT)

In the context of BPD, CBT as a therapeutic modality focuses on helping the individual to recognise and understand patterns of unhelpful thoughts and behaviours, thereby supporting their modification (American Psychiatric Association, 2013).
CBT thus supports the individual with BPD to explore their thoughts, challenge self-limiting or unhelpful thoughts and beliefs, and develop more positive, balanced ways of thinking.

Dialectical behavioural therapy (DBT)

DBT, as a therapeutic modality, focuses on mindfulness, distress tolerance, emotional regulation, and interpersonal effectiveness, thereby improving emotional resilience against psychological challenges.
Linehan (1993) note thus that DBT is thus particularly effective for individuals with BPD as a therapeutic modality.

Schema-focused therapy (SFT)

SFT helps to promote healthier emotional regulation and management mechanisms in the context of deep-rooted patterns (schemas) formed during childhood, theorised to form part of the etiology of BPD in affected individuals (Young et al., 2003).
Thus, SFT teaches individuals with BPD healthier coping mechanisms for long-term recovery.

Mentalisation-based therapy (MBT)

MBT focuses on developing psychological skills for individuals with BPD to interpret and respond to others’ emotions and intentions, thereby improving relationship dynamics via fostering understanding of theory of mind (Bateman and Fonagy, 2004)

Group therapy

Group therapy provides a supportive environment for individuals with BPD and other personality disorders to share their experiences and learn psychological skills which can support individuals with BPD to manage their emotions better and overcome the challenges of living with BPD.

Managing Life With Borderline Personality Disorder

Living with BPD can be challenging.

However, adopting some of the following techniques as part of general lifestyle changes can enhance emotional stability and daily functioning, thereby supporting BPD management:

Build a support network, surrounding yourself with trusted friends, family, and therapists who can provide emotional support.
Practice mindfulness; activities such as meditation and grounding exercises can help reduce emotional reactivity in BPD (Linehan, 1993) thereby fostering emotional wellbeing.
Develop healthy coping mechanisms, replacing impulsive behaviors with productive activities such as exercising, journaling, or engaging in creative arts.
Adhering to your treatment plan: attend therapy sessions consistently and follow prescribed treatments (including prescribed medication, where indicated by your psychiatrist/doctor) for long-term progress.
Educate yourself and others; raising awareness about BPD reduces stigma and fosters understanding.

Relationships and Borderline Personality Disorder

BPD can present unique challenges in relationships. Effective approaches to managing BPD within relationships can thus include:

Open communication, maintaining transparency about emotions and expectations.
Setting boundaries, wherein clear, respectful boundaries are established and set in order to build trust.
Couples or family therapy, where it is important to work through issues collaboratively to strengthen relationships.

When to Seek Professional Help

If you or someone you know is struggling with BPD, it’s important to seek help if you notice:

Consistent emotional instability or impulsive behaviors.
Frequent self-harm or suicidal thoughts.
Difficulty maintaining relationships and/or performing daily tasks.

Early intervention can thereby prevent worsening symptoms, promoting lasting mental health improvements.

By attending ongoing therapy, having a strong support system, and dedication to self-care, many individuals with BPD go on to lead meaningful and happy lives.

Borderline Personality Disorder may be complex, but it is treatable with the appropriate resources and therapies.

Through understanding its symptoms, causes, and treatment options, individuals and their loved ones can work toward emotional stability and healthier relationships.

If you or someone you know is living with BPD, don’t hesitate to seek help. A mental health professional can guide you on the path to recovery and growth.

Remember—healing is possible, and a brighter future awaits!

Conclusion:

Borderline Personality Disorder is a challenging, yet treatable, mental health condition. Its etiology is complex, including the risk factors of genetic predisposition, environmental stressors, and neurobiological factors; BPD can thereby lead to intense emotional and interpersonal difficulties.

However, via a range of evidence-based treatments including CBT, DBT, schema-focused therapy, and mentalisation-based therapy, many individuals with BPD can find effective ways to manage their symptoms and lead a fulfiling life.

Building a supportive network of friends, family and committing to ongoing therapy are positive, vital steps for individuals with BPD to develop emotional stability and improved relationships. By recognising the symptoms early and seeking professional help, individuals with BPD can lead fulfiling lives and overcome the challenges they face.
