What Causes Borderline Personality Disorders?

Borderline Personality Disorder (BPD) is a complex mental health condition characterized by extreme mood swings, impulsive behaviour, and unstable relationships. While the exact causes of Borderline Personality Disorders are unknown, researchers have identified several risk factors that increase the likelihood of developing this mental health condition.

Biological Factors

Studies have shown that biological factors such as genetics, brain chemistry, and childhood trauma can play a role in the development of BPD.

What Causes Borderline Personality Disorders – Genetics

Researchers have not yet identified specific genes that are directly linked to the BPD. However, studies have shown that the condition has a strong hereditary component. The condition tends to run in families, and individuals who have a first-degree relative with BPD are at a higher risk of developing the disorder.

In fact, research has shown that individuals with a first-degree relative with BPD are five times more likely to develop the disorder themselves compared to those without a family history of the disorder. This suggests that genetics do play a role in the development of BPD, although the exact mechanisms are not yet understood.

It’s important to note that genetics are not the only factor in determining the development of BPD. Environmental factors, such as childhood abuse or neglect, can also play a significant role. Additionally, having a family history of BPD does not necessarily mean that an individual will develop the disorder. It simply means that they may be at a higher risk compared to the general population.

What Causes Borderline Personality Disorders – Brain Chemistry

Neuroimaging studies have provided important insights into the underlying neurological changes that occur in individuals with Borderline Personality Disorder. These studies have revealed that there are notable differences in the brain structure and function of people with BPD compared to those without the disorder.

One key difference is that people with BPD tend to have less activity in the prefrontal cortex of the brain, which is responsible for regulating emotions and decision-making. This area of the brain is essential for regulating impulsive behavior and managing emotions in a healthy way. A lack of activity in the prefrontal cortex can make it difficult for individuals with BPD to control their emotions and impulses, leading to impulsive and self-destructive behaviors.

In contrast, individuals with BPD tend to have more activity in the amygdala of the brain, which is responsible for processing emotions. This heightened activity in the amygdala can contribute to the intense mood swings and emotional instability that are characteristic of BPD. It can also make it difficult for individuals with the disorder to regulate their emotions and respond appropriately to emotional situations.

What Causes Borderline Personality Disorders – Childhood Trauma

Childhood experiences play a significant role in the development of Borderline Personality Disorder (BPD). Studies have found that individuals with the disorder are more likely to have experienced childhood trauma, such as physical, emotional, or sexual abuse, neglect, or separation from caregivers.

These traumatic childhood experiences can lead to a number of negative outcomes that contribute to the development of BPD. For example, they can disrupt attachment patterns between children and their caregivers, leading to anxiety, frustration and anger. Disrupted attachment patterns can also make it difficult for individuals to form healthy relationships later in life.

Emotional dysregulation is also common among people who have experienced childhood trauma. This means that they have difficulty regulating and managing their emotions and often experience intense and overwhelming emotional responses to seemingly minor events. This emotional dysregulation can fuel behaviours such as self-harm, substance abuse, and impulsive behaviour.

Additionally, individuals with BPD who have experienced childhood trauma may struggle with a deep-seated sense of emptiness, lack of identity and self-esteem. This can manifest as a desire for validation from others and a fear of abandonment.

Environmental Factors

While biological factors play a role in the development of BPD, environmental factors such as family dynamics and social relationships also contribute to the disorder.

What Causes Borderline Personality Disorders – Family Dynamics

Dysfunctional family dynamics are a significant factor in the development of Borderline Personality Disorder (BPD). High conflict, neglect, inconsistent parenting, and other difficult family situations can all contribute to the development of BPD.

Growing up in a chaotic or unstable household can lead to feelings of insecurity, anxiety and low self-esteem, which can lead to or worsen BPD symptoms. Family dynamics characterized by chronic conflict or neglect can make it difficult for children to develop a strong and stable sense of identity, which can be extremely damaging for individuals with BPD.

Inconsistent parenting often plays a major role, too. For example, a parent who is loving and supportive one moment and then angry and distant the next can leave a child feeling confused and insecure. This inconsistency may lead to anxiety, depression or parentification – when a child is pressured to take on parental responsibilities.

What Causes Borderline Personality Disorders – Social Relationships

People with Borderline Personality Disorder (BPD) often experience significant difficulties in their social relationships. These individuals may fear abandonment to such an extent that they strive to keep their partners or friends in constant proximity, becoming highly dependent or clinging. They may worry that any perceived rejection or criticism will lead to abandonment, resulting in feelings of intense distress, anger, and hurt.

Individuals with BPD are also known for their impulsivity. Impulsive behaviours such as reckless spending, substance abuse, or promiscuity can strain relationships or even end them.

Volatile emotions can also cause issues in social relationships. Intense emotions, such as anger and sadness, can escalate quickly, sometimes causing other people to respond by withdrawing from the relationship in attempts to protect themselves. Conflicts and arguments may also occur frequently due to the emotional intensity of individuals with BPD.

These relationship problems contribute to social isolation, rejection, and loneliness, which in turn may worsen BPD symptoms. Additionally, individuals with BPD may experience difficulties in receiving treatment because of a belief that they are either inherently flawed or that others are abandoning them. This can make it difficult to establish a trusting relationship with a therapist or other mental health professional.

What is the Outlook for Someone Who Has Borderline Personality Disorder?

The outlook for someone who has Borderline Personality Disorder (BPD) greatly depends on their individual experience, the severity of their symptoms, and how well they respond to treatment.

For some individuals with BPD, symptoms may be mild, and they may be able to manage them with therapy, medication, and other support. These individuals may be able to maintain healthy relationships and live a full, satisfying life.

For others, BPD symptoms may be severe and cause significant disruptions in their daily life, relationships and work. Individuals with more severe symptoms may struggle with consistent relationships, social isolation, or self-destructive behaviour. In these cases, long-term therapy may be necessary, as well as medications, hospitalization or crisis intervention at times.

Historically, BPD has been viewed as a difficult and treatment-resistant condition. However, this is changing with the development of newer, more evidence-based therapies such as Dialectical Behavior Therapy (DBT), which has proven to be effective in treating BPD.

Conclusion

While the exact causes of borderline personality disorders are unknown, researchers have identified several risk factors that increase the likelihood of developing the disorder. Biological factors such as genetics, brain chemistry, and childhood trauma can play a role, as can environmental factors such as family dynamics and social relationships. Understanding these risk factors can help mental health professionals identify and treat BPD more effectively.

With the right treatment, individuals with BPD can learn to develop better emotional regulation skills, become more self-aware, and learn more effective ways to cope with stressful situations which can improve their outlook. It is important to note that while not everyone with BPD will experience remission or the elimination of symptoms, many players report significant improvement that enables them to live a fulfilled life.
