Borderline Personality Disorder is a serious condition which is believed to affect between 1-3% of the general population. Yet, despite being so prevalent, BPD is not commonly understood.
People who live in a relationship with a person who suffers from borderline personality disorder often know that something is terribly wrong with the behavior of their family member or loved-one but often do not know what to do about it or that there is even a name for it.
There are a number of different names used around the world for the same disorder:
Borderline Personality Disorder (BPD)
Emotional Regulation Disorder (ERD)
Emotional Dysregulation Disorder
Emotional Intensity Disorder (EID)
Emotionally Unstable Personality Disorder (EUPD)
Emotion-Impulse Regulation Disorder (EIRD)
Impulsive Personality Disorder (IPD)
The most commonly used name today is Borderline Personality Disorder - or BPD - as defined in the American Psychiatric Association’s Diagnostic & Statistical Manual (DSM-IV-TR).
The term "Borderline" is a historic term coined to describe people who were diagnosed to be on the borderline between a neurotic and psychotic disorder. It is commonly felt that the "Borderline" label is misleading and stigmatizes the disorder. The fifth version of the Diagnostic & Statistical Manual (DSM-V) is scheduled for release in 2010. It is likely that the disorder will be renamed Emotional Regulation Disorder (ERD) or Emotional Dysregulation Disorder (EDD) in the DSM-V.
Characteristics & Traits
The following list is a collection of some of the more commonly observed behaviors and traits of those who suffer from BPD /ERD. Click on the links on each one for more information about a particular trait or behavior and some ideas for coping with each.
Note that these traits are given as a guideline only and are not intended for diagnosis. People who suffer from BPD are all unique and so each person will display a different subset of traits. Also, note that everyone displays "borderline" behaviors from time to time. Therefore, if a person exhibits one or some of these traits, that does not necessarily qualify them for a diagnosis of BPD. See the DSM Criteria on this page for diagnostic criteria.

An estimated 2% of the US population is estimated to meet the clinical criteria for BPD. However, prevalence results vary widely as shown below. A number of studies have been performed to determine the prevalence of personality disorders and BPD. Prevalence results indicate that BPD affects anywhere between 0.5 and 5.9% of adults
People who have a first-degree relative with BPD are five times more likely to develop BPD themselves. Those who suffer child abuse are also more likely to develop BPD.
Some people who suffer from BPD are prone to suicidal behaviors and self-injury, especially as adolescents. About 8%-10% of diagnosed BPD patients commit suicide.

Borderline Personality Disorder (BPD) - The DSM Criteria
Borderline Personality Disorder (BPD) is listed in the American Psychiatric Association’s Diagnostic & Statistical Manual (DSM) as an Axis II, Cluster B (dramatic, emotional, or erratic) Disorder:
A pervasive pattern of instability of interpersonal relationships, self-image, and affects, and marked impulsivity beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following:
Frantic efforts to avoid real or imagined abandonment. [Not including suicidal or self-mutilating behavior covered in Criterion 5]
A pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation.
Identity disturbance: markedly and persistently unstable self-image or sense of self.
Impulsivity in at least two areas that are potentially self-damaging (e.g., spending, promiscuous sex, eating disorders, substance abuse, reckless driving, binge eating). [Again, not including suicidal or self-mutilating behavior covered in Criterion 5]
Recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior.
Affective instability due to a marked reactivity of mood (e.g., intense episodic dysphoria, irritability, or anxiety usually lasting a few hours and only rarely more than a few days)
Chronic feelings of emptiness.
Inappropriate, intense anger or difficulty controlling anger (e.g., frequent displays of temper, constant anger, recurrent physical fights).
Transient, stress-related paranoid ideation or severe dissociative symptoms.
BPD / ERD Treatment
There is no known cure for BPD / ERD. As a result, families of people who suffer from BPD / ERD are often left to fend for themselves and rely on their own resources.
However, some treatments do exist which have proven effective in managing symptoms. The most common approach is the combination of SSRI medication and DBT Therapy.
DBT - Dialectical Behavioral Therapy
Dialectical Behavioral Therapy - Dialectical Behavioral Therapy (DBT) is a psychosocial treatment developed for patients with borderline personality disorder which combines intensive individual and group therapy.
Dialectical Behavioral Therapy (DBT) was developed for treating Borderline Personality Disorder by Marsha M. Linehan. Some therapists avoid treating patients whom they suspect may suffer from BPD, because of the demands some BPD patients put on the therapist. These demands include multiple phone calls after hours, suicidal ideation and suicidal threats, lack of respect for the therapist's boundaries or the boundaries of other patients and staff, aggressive outbursts and stalking.
DBT incorporates an intense program of weekly individual therapy sessions and weekly group therapy sessions.
Individual therapy focuses on addressing a prioritized set of issues starting with self-injury, then behaviors which disrupt therapy, then behaviors which disrupt healthy living. Patients are trained in a regime of four skills known as mindfulness, emotion regulation, interpersonal effectiveness and distress tolerance.
SSRI's - Selective Serotonin Reuptake Inhibitors
SSRI - Selective Serotonin Reuptake Inhibitors, are the most commonly prescribed antidepressants for people who suffer from personality disorders. Popular SSRI's include Celexa, Lexapro, Prozac, Paxil, & Zoloft.
SSRI's relieve symptoms of depression by blocking the re-absorption (re-uptake) of a neurotransmitter in the brain called serotonin. More serotonin in the brain has been shown to improve mood.
SSRI's are generally considered milder than other types of antidepressants. Therefore, SSRI's are typically the first line of approach for practitioners.
Side-effects include: nausea, sexual dysfunction, headache, diarrhea, nervousness, rash, agitation, restlessness, sweating, weight gain, drowsiness and sleeplessness.
BPD Possible Causes
The causes for BPD are not precisely known. However, recent research has turned up some clues. Further study is necessary to definitively establish a cause. However, theories do exist.
There is some evidence relating the prevalence of BPD to the kind of environment a child grew up in. A significant percentage of people who suffer from BPD were also abused as children. However, this kind of correlation does not always prove that the environment they grew up in contributed to their own disorder - read our section on the Post Hoc Ergo Propter Hoc Fallacy for a possible explanation why.)
There is a higher incidence of personality disorders in those who have parents who suffer from a personality disorder. This has led some scientists to suspect there may be a genetic link for BPD.
There is also a higher incidence of BPD in females. Read our section on the Amygdala for some information on gender differences in neural activity which may some day lead to a greater understanding of why certain disorders may afflict one gender more than another.
The Amygdala and it's Link to BPD / ERD
Amygdala - The Amygdala is a small region of the brain which plays a key role in emotional regulation, emotional memory and responses to emotional stimuli.
Recent technological advances have given neurologists two new ways to create 3-D images of the brain. These techniques are known as Positron Emission Tomography (PET Scanning) and functional Magnetic Resonance Imaging (fMRI). By scanning a person's brain while prompting them to think in a certain way, scientists are unlocking clues as to which regions of the brain are responsible for different kinds of thought.
Much of this work has focused on the amygdala - a small region deep in the brain shown below. There is one amygdala the right side of the brain and one on the left as shown below.
It is believed that the amygdala has an important rule in producing lightning-fast emotional responses to events, whenever a person recognizes an event with a strong emotional element (good or bad) such as events that results in fear, anger or rage or events that result in delight, joy or excitement.
The amygdala is believed to be part of our fast, instinctive and reactive brains. Not much conscious thought is involved if an object is hurled towards us and we instinctively duck. This ability to react instinctively to danger is thought to have historically played a critical function in survival of most species. Similarly, witness the reaction of a crowd whenever a sports team scores a goal. There is a universal instant response of throwing hands in the air, widening the eyes, leaping into the air etc, without much thought given. When you see these instinctive reactions occur, the amygdala is at work.
The Amygdala and Memory
The amygdala has also been shown to have an important function in enhancing memory functions by releasing stress hormones, such as adrenaline. It has been shown experimentally that rats, who have had their amygdala disabled lose their fear of cats. It has also been shown that increasing stress hormones improves memory of an event. This helps explain why people can remember stressful moments in great detail - such as times of disasters or crises, when adrenaline is released and yet can easily forget long periods when nothing significant seems to have happened.
Gender Differences in the Way the Amygdala is Connected
Another interesting finding resulted from a study comparing amygdala activity in males and females. When shown images containing strong emotionally arousing content, it was found that the amygdala on the right side of the brain was the most active in men, while the amygdala on the left side of the brain was most active in women.
Other experiments with people who are relaxing have shown that in men, the right amygdala is more closely connected to the rest of the brain than the left, while women show a stronger connectivity between the left amygdala and the rest of the brain. Additionally, in men the right amygdala seems to be strongly connected to regions of the brain normally associated with interactions with the external environment while in women, the left amygdala seems to be strongly connected to regions of the brain normally associated with more internal thought. This suggests that in an emotional context, men are biased toward thoughts about the external environment and women toward thoughts about the internal environment.
The Link between the Amygdala and Emotional Regulation Disorder / Borderline Personality Disorder
In a famous experiment at Yale University, 15 people diagnosed with BPD and 15 people with no BPD diagnosis were shown photographs of faces with neutral, happy, sad, and fearful facial expressions while mapping the activity in the brain using fMRI. It was found that there is a lot more activity in the left amygdala of people who had been diagnosed with Emotional Regulation Disorder /Borderline Personality Disorder when exposed to an emotional stimulus than there is for most other people.
Borderline Personality Disorder (BPD) and Bipolar Disorder are similar in that both are characterized by dramatic changes in mood. It is thought that many people who suffer from BPD are inaccurately diagnosed as having Bipolar disorder because it generally carries less stigma and is easier to treat with pharmaceuticals. However, there are also some important differences between Bipolar & BPD:
Frequency of Mood Cycles
Mood swings for people who suffer from Borderline Personality Disorder typically cycle much faster than for people who suffer from Bipolar Disorder. BPD sufferers often exhibit mood cycles lasting from a few hours to a few days. People who suffer from Bipolar Disorder typically exhibit mood swings lasting from a few weeks to a few months.
It should be noted that some Bipolar patients are characterized or diagnosed with Rapid Cycling Bipolar Disorder which has the same symptoms as Bipolar Disorder but with a shorter cycle time.
People who suffer from BPD often exhibit an acute Fear of Abandonment. The mood swings a person with BPD exhibits are often attached to their fear of being left alone or their preoccupation with not being alone. Sometimes, BPD is described as a "relationship disorder" in that it manifests itself in interactions with others.
Bipolar Disorder tends to be less relationship-based. People who suffer from Bipolar Disorder often display cycles of mood which are more inwardly self-focused and have less to do with how they feel about the relationships they are involved in.
Borderline Personality Disorder comprises both psychotic & neurotic thought processes. This gives rise to the name "Borderline" because it is thought to be on the "borderline" between psychosis & neurosis. The thinking and behavior of a person with Borderline Personality Disorder includes more mental departures from reality, known as Dissociation or "feelings create facts".
In contrast, Bipolar Disorder tends to be more neurotic in that the mood swings tend to be based more on extreme exaggerations of fact.
Response To Treatment
People who suffer from Bipolar Disorder often respond positively to appropriate regimes of medication.
People who suffer from Borderline Personality Disorder may also exhibit some improvement when treated with appropriate medication but typically also require extensive therapeutic intervention such as DBT over a period of months or years in order to see comparable results.
Both groups are often reluctant to seek help and may be resistant to medication. Also, both groups have a tendency to stop taking prescribed medications when they begin to feel better which often leads to relapses.

August 25, 2014 - OOTF announce an exciting new development - it's called Out of the Storm - a support site specifically designed for people who suffer from CPTSD - Complex Post Traumatic Stress Disorder. At OOTF we have often welcomed members who are dealing with CPTSD as a consequence of having been in a relationship with someone who suffers from a personality disorder. Nevertheless, for a long time we have recognized that CPTSD sufferers have a distinct and unique set of concerns and issues.
Nov 9, 2013 - OOTF has just launched a new "Future Goals" forum. This forum is a safe place to store your goals of what you would like to achieve. Setting goals can help us move forward, and give us something to focus on while we are working our way through day to day issues. Goals can change, be amended or added to over time as we either achieve them, or determine new goals as our lives unfold.
