**Borderline personality disorder** (**BPD**) is a long-term mental illness. It is a type of cluster B personality disorder. People diagnosed with it are often very impulsive and have low self-esteem. Moods often change quickly. For these reasons, people with BPD often have trouble keeping stable relationships. Frequently, people with BPD also suffer from other conditions, such as clinical depression or show self-harming behavior. Treating people with BPD is difficult and is usually done using a combination of drugs and therapy, especially dialectical behavior therapy and schema therapy.

C.H. Huges used the term "Borderland", to describe a number of conditions bordering mental health issues.  Adolf Stern described of some of the symptoms in 1938 and called them "border line group". This term described people who were on the "borderline" of conditions related to psychosis and related to neurosis.

## Symptoms 
People diagnosed with BPD have strong mood swings. They see things as "all good" or "all bad" (splitting) and are frequently confused about their identity. They usually have a lot of trouble with relationships with people. They have strong emotions, which often change quickly. They are often reckless, destructive or self-destructive.

### Emotions 
People with BPD feel emotions more easily, more deeply and for longer than others do. Emotions may repeatedly return and last a long time. Because of this, it may take longer than normal for people with BPD to return to a typical and stable emotional state. This can have both positive and negative effects. People with BPD often switch between being loving and happy to being sad and angry. They feel emotions in a stronger way than most people --  instead of sadness,  instead of being , and  instead of being . People with BPD are especially sensitive to feelings of being , being alone, and being a "failure". They are often aware of how strong their emotions are, and, since they cannot control them, they sometimes shut them down entirely.

Their emotions are intense, and their emotions are also quick to change. The most common mood swings they have are between anger and anxiety and between depression and anxiety.

### Behavior 
People with BPD often act impulsively, which means they often do things or say things without thinking. This behavior can be dangerous and can include: abusing drugs or alcohol, eating too much or too little, having unsafe sex or frequent sex with multiple partners, spending a lot of money, and driving dangerously. Impulsive behavior may also include leaving jobs or relationships, running away, and self-injury.

People with BPD sometimes act impulsively because it gives them instant relief from their emotional pain. However, in the long term, people with BPD go through more pain from the shame and guilt that follow these actions. A cycle often begins where people with BPD feel emotional pain and act impulsively to relieve that pain. Then they feel bad about what they did and have strong  to act impulsively to relieve the new pain. As time goes on, impulsive behavior may start to be an automatic reaction to emotional pain.

### Self-harm and suicide 
Self-injury is common for people with BPD. Sometimes, people hurt themselves without wanting to commit suicide. Common methods include cutting, burning, head banging, and drug overdose. The reasons that people with BPD give for non-suicidal self-injury are different from their reasons for suicide attempts. Reasons they give for hurting themselves include expressing anger, punishing themselves, creating normal feelings, and  themselves from emotional pain or difficult situations. Their feelings about others often switch from positive to negative if they feel like they might lose someone, if they think someone important to them does not care about them, or if something is not as good as they expected. They often think in extremes, seeing things or people as "all good" or "all bad". This is sometimes called black-and-white thinking. It includes a change from  someone to  them, often feeling pure anger or dislike. The way they see themselves can also change quickly from positive to negative.

While strongly wanting to feel closeness, people with BPD tend to be anxious, have mixed feelings, or be  when it comes to their relationships. They often view the world as dangerous and bad.

### Sense of self 
People with BPD tend to have trouble seeing a clear picture of their identity. It is difficult for them to know what they value and love. They often do not know about their long-term goals for relationships and jobs. They often have trouble making decisions and can change their minds quickly. These difficulties can cause people with BPD to feel "empty" and "lost".

### Cognitions 
People with BPD are easily bored, and it is hard for them to . People with BPD may tend to disconnect or "dissociate" from people and things around them, which can be thought of as an intense form of "zoning out". This often happens in response to a painful event, or something that triggers the memory of a painful event. This can make the person feel better for a short time, but it can also have the unwanted side effect of blocking ordinary feelings. This has the result of keeping people with BPD from learning how to handle these feelings and can make it difficult for them to make positive choices when they feel these emotions. Sometimes, other people can see when someone with BPD is dissociating because the expressions in their voice or face can seem emotionless, or they look like they are distracted. Sometimes, when someone with BPD is dissociating, other people are not able to see or know that it is happening.

## Diagnosis 
Psychiatrists and other mental health professionals diagnose people with BPD using a book called the *Diagnostic and Statistical Manual of Mental Disorders* (DSM-IV-TR). They look at a person's behavior and how they are feeling. If the person has five or more of the following signs, the DSM-IV-TR says that they have BPD.

# Fearing and trying very hard to prevent being left or rejected
# A pattern of trouble in relationships, often thinking that other people are much better or much worse than they really are and changing quickly between the two views
# Being confused about their own personal identity
# Being impulsive in ways that are dangerous (such as casual sex, drinking too much alcohol or abusing drugs, not eating or eating too much, driving dangerously)
# Trying to commit suicide, or hurting themselves
# Mood swings - suddenly feeling very happy, sad or anxious, and feeling that way for hours at a time
# Feeling empty inside or constantly feeling bored
# Having intense anger problems, getting into many fights
# Having severe paranoid thoughts
BPD is also commonly mistaken for other mental health disorders, which may lead a patient to have several diagnoses before obtaining the correct one. Most commonly, BPD is mistaken for bipolar disorder, due to the fluctuations in mood that characterize both disorders. There are several key distinctions that are useful to note whilst distinguishing the two. The duration of fluctuations is shorter and do not remain constant, as seen in bipolar disorder. Similarly, mood changes in BPD are typically triggered by external events, with heightened sensitivity to rejection, failure, and abandonment, shifting between depression and intense anger. 

Other illnesses that often happen with BPD include diabetes, high blood pressure, chronic back pain, arthritis, and fibromyalgia.

## Cause 
The cause for BPD is not known. There may be several causes for people developing BPD. Some researchers think that it might be caused by trauma in childhood, such as sexual abuse, physical abuse and neglect. Many people with BPD were abused when they were children. Modern thinking as demonstrated by functioning MRI scans is that neurotransmitters within the brain are not working correctly, and messages are not  in the usual way. 

Some studies of twins and families suggest that personality disorders may be inherited or strongly associated with other mental health disorders among family members.

## Risk factors 
Some factors related to personality development can increase the risk of developing borderline personality disorder. These include:

* **Hereditary predisposition.** People may be at a higher risk if a close family member has it or a similar disorder.
* **Stressful childhood.** Many people with the disorder report being neglected or abused during childhood. Some people have lost or were separated from a parent when they were young or had parents with addictions or other mental health issues. Others have been exposed to hostile conflict and unstable family relationships.

## Treatment 
Treating BPD is very difficult and takes a long time. Today, most people with BPD are treated with different kinds of psychotherapy. One of these is called dialectical behavioral therapy. In addition to therapy, drugs such as antidepressants, antipsychotics or mood stabilizers are often used. Many sufferers recover within 10 years.
