What is Borderline Personality Disorder?

BPD Blog IBorderline personality disorder (BPD) is a serious condition which causes difficulties in effectively regulating emotions. People with BPD experience the world in extremes, leading to wide fluctuations in their behavior, thoughts, emotions, relationships and sense of self and often creating significant damage to life goals, relationships and day-to-day functioning.

Borderline Personality Disorder Symptoms 

The signs and symptoms may include:

  • Patterns of intense and unstable interpersonal relationships with extremes of idealization and devaluation such as “I love her” and “I hate her.”
  • Frantic efforts to avoid real or imagined abandonment from family, significant others and friends.
  • Identity disturbance or problems with sense of self (looks toward the environment for self-definition and value).
  • Impulsivity that is potentially self-damaging (spending too much money, reckless driving, sexual relationships, substance use, etc.).
  • Recurrent suicidal or self-injurious behavior.
  • Mood instability which changes within a few hours to days.
  • Chronic feelings of emptiness.
  • Inappropriate, intense or uncontrollable anger which is typically followed by shame and guilt.
  • Transient stress-related paranoid ideation (caused by stress and not a sign of psychosis) or severe dissociative symptoms.

As many as 5.9% of American adults may struggle with Borderline Personality Disorder.  

That’s 14 million people – more than the percentage of people diagnosed with schizophrenia and bipolar disorder combined! However, because BPD is highly stigmatized it is often underdiagnosed and undertreated. In the past, BPD was thought of as “untreatable” or caused by a history of family sexual abuse. Due to these misperceptions many people are not accurately diagnosed. It is common for people to recognize they have the symptoms of BPD, but due to their negative perception of BPD they reject the diagnosis in fear and don’t seek treatment due to shame.

What is the Cause of Borderline Personality Disorder?

BPD Blog IIBPD results from a person with biological vulnerabilities living in an environment that is a poor fit for coping with their biological temperament.  People with BPD have a high biological sensitivity to emotion.

In recent years, researchers have determined people with BPD have a small or underactive anterior cingulate which is the part of the frontal cortex that puts the brakes on emotions. This less functional anterior cingulate in people with BPD causes them to be flooded with emotions even if they “know” the situation shouldn’t be that emotionally charged. This leads to frequent and intense feelings of confusion, overstimulation and fear.

Due to this emotional state, they often look to others rather than themselves for an accurate reflection of reality.  If their social environment does not have an understanding of this emotional process, it is common that unintentional invalidation occurs.

A person who is biologically emotionally vulnerable experiences this invalidation with more intensity than an emotionally healthy person. This intense sensitivity could be compared to being a burn victim and having someone touch your skin verses a person with healthy skin being touched.

As a result people with BPD can have unrealistic goals, experience extreme shame and struggle to use rewards rather than punishment in reaching goals. They often struggle with poor self-regulation, self-punishment and self-hate regarding the failure to reach goals. Unfortunately, the person with BPD’s reactions often triggers more invalidation in the environment.

Over time, this cycle develops the disorder of BPD. Neither biology and heredity nor invalidating environments alone cause BPD.

Health is Possible

Despite historical misperceptions, treatment is effective for BPD. One leading, evidence-based treatment for BPD is Dialectical Behavioral Therapy, an intensive outpatient treatment program with its foundations in cognitive behavioral therapy. The goal of treatment is to guide and support people in mastering the skills and attitudes to build a “life worth living.”

In addition, help is available for those with a loved one suffering from BPD symptoms. Pine Rest offers a 4-session Family and Friends Class that helps to increase the understanding of the illness and equip family and friends with tools for coping effectively.
