Facts on borderline personality disorder

NIMH » Borderline Personality Disorder

What is borderline personality disorder?

Borderline personality disorder is a mental illness that severely impacts a person’s ability to regulate their emotions. This loss of emotional control can increase impulsivity, affect how a person feels about themselves, and negatively impact their relationships with others. Effective treatments are available to manage the symptoms of borderline personality disorder. Learn more about the disorder, how it’s diagnosed, and how to find support.

What are the signs and symptoms?

People with borderline personality disorder may experience intense mood swings and feel uncertainty about how they see themselves. Their feelings for others can change quickly, and swing from extreme closeness to extreme dislike. These changing feelings can lead to unstable relationships and emotional pain.

People with borderline personality disorder also tend to view things in extremes, such as all good or all bad. Their interests and values can change quickly, and they may act impulsively or recklessly.

Other signs or symptoms may include:

Efforts to avoid real or perceived abandonment, such as plunging headfirst into relationships—or ending them just as quickly.
A pattern of intense and unstable relationships with family, friends, and loved ones.
A distorted and unstable self-image or sense of self.
Impulsive and often dangerous behaviors, such as spending sprees, unsafe sex, substance abuse, reckless driving, and binge eating. Please note: If these behaviors happen mostly during times of elevated mood or energy, they may be symptoms of a mood disorder and not borderline personality disorder.
Self-harming behavior, such as cutting.
Recurring thoughts of suicidal behaviors or threats.
Intense and highly variable moods, with episodes lasting from a few hours to a few days.
Chronic feelings of emptiness.
Inappropriate, intense anger or problems controlling anger.
Feelings of dissociation, such as feeling cut off from oneself, observing oneself from outside one’s body, or feelings of unreality.

Not everyone with borderline personality disorder may experience all of these symptoms. The severity, frequency, and duration of symptoms depend on the person and their illness.

People with borderline personality disorder have a significantly higher rate of self-harming and suicidal behavior than the general population.

People with borderline personality disorder who are thinking of harming themselves or attempting suicide need help right away.

If you or someone you know is in immediate distress or is thinking about hurting themselves, call the National Suicide Prevention Lifeline toll-free at 1-800-273-TALK (8255). You also can text the Crisis Text Line (HELLO to 741741) or use the Lifeline Chat on the National Suicide Prevention Lifeline website.

What causes borderline personality disorder?

Researchers aren’t sure what causes borderline personality disorder, but studies suggest that genetic, environmental, and social factors may increase the risk of developing it. These factors may include:

Family history: People who have a close family member (such as a parent or sibling) with the illness may be at a higher risk of developing borderline personality disorder.
Brain structure and function: Research shows that people with borderline personality disorder may have structural and functional changes in the brain, especially in the areas that control impulses and emotion regulation. However, the studies do not demonstrate whether these changes were risk factors for the illness or if such changes were caused by the disorder.
Environmental, cultural, and social factors: Many people with borderline personality disorder report experiencing traumatic life events, such as abuse, abandonment, or hardship during childhood. Others may have been exposed to unstable, invalidating relationships or conflicts.

Although these factors may increase a person’s risk, it doesn’t mean it is certain that they’ll develop borderline personality disorder. Likewise, people without these risk factors may develop the disorder in their lifetime.

How is borderline personality disorder diagnosed?

A licensed mental health professional—such as a psychiatrist, psychologist, or clinical social worker—who is experienced in diagnosing and treating mental disorders can diagnose borderline personality disorder based on a thorough interview and a discussion about symptoms. A careful and thorough medical exam also can help rule out other possible causes of symptoms. In diagnosing the illness, providers will discuss a person’s symptoms and ask about family medical histories, including histories of mental illness.

Borderline personality disorder is usually diagnosed in late adolescence or early adulthood. Occasionally, a person younger than age 18 may be diagnosed with borderline personality disorder if symptoms are significant and last at least a year.

What other illnesses can co-occur with borderline personality disorder?

Borderline personality disorder often occurs with other mental illnesses, such as post-traumatic stress disorder (PTSD). These co-occurring disorders can make it harder to diagnose and treat borderline personality disorder, especially if symptoms of other illnesses overlap with symptoms of the disorder. For example, a person with borderline personality disorder also may be more likely to experience symptoms of major depression, PTSD, bipolar disorder, anxiety disorders, substance abuse, or eating disorders.

How is borderline personality disorder treated?

Borderline personality disorder historically has been viewed as challenging to treat. But with newer, evidence-based treatment, many people with this disorder experience fewer and less severe symptoms, improved functioning, and better quality of life. It is important for patients with borderline personality disorder to receive treatment from a licensed mental health professional. Other types of treatment, or treatment from a provider who is not appropriately trained, may be ineffective or dangerous.

Many factors affect the length of time it takes for symptoms to improve once treatment begins. It is important for people with borderline personality disorder and their loved ones to be patient and receive support during treatment.

It is important to seek—and stick with—treatment.

Studies funded by the National Institute of Mental Health (NIMH) indicate that individuals with borderline personality disorder who don’t receive adequate treatment are more likely to develop other chronic medical or mental illnesses and are less likely to make healthy lifestyle choices.

Psychotherapy

Psychotherapy, sometimes called “talk therapy,” is the first-line treatment for people with borderline personality disorder. Most psychotherapy occurs with a licensed, trained mental health professional in one-on-one sessions or with other individuals in group settings. Group sessions may help teach people with borderline personality disorder to interact with others and express themselves effectively.

Two examples of psychotherapies used to treat borderline personality disorder are:

Dialectical Behavior Therapy (DBT): This treatment was developed specifically for individuals with borderline personality disorder. DBT uses concepts of mindfulness or awareness of one’s present situation and emotional state. DBT also teaches skills to help people control intense emotions, reduce self-destructive behaviors, and improve relationships.
Cognitive Behavioral Therapy (CBT): This treatment can help people identify and change core beliefs and behaviors that come from inaccurate perceptions of themselves and others and problems interacting with others. It may help people reduce mood swings and anxiety symptoms and may reduce the number of self-harming or suicidal behaviors.

Medications

Because the benefits of prescription medication for borderline personality disorder are unclear, medications aren’t typically used as the primary way to treat the illness. However, in some cases, a psychiatrist may recommend medications to treat specific symptoms or co-occurring mental disorders such as mood swings or depression. Treatment with medications may require coordinated care from more than one medical professional.

Medications also can sometimes cause side effects in some people. Talk to your provider about what to expect from a particular medication. Read more on NIMH’s mental health medications webpage.

Where can I find help?

If you’re not sure where to get help, a health care provider can refer you to a licensed mental health professional, such as a psychiatrist or psychologist with experience treating borderline personality disorder. If you need help starting the conversation, check out the Tips for Talking With Your Health Care Provider fact sheet.

Therapy for Caregivers and Family Members

Having a relative or loved one with the disorder can be stressful, and family members or caregivers may unintentionally act in ways that can worsen their loved one’s symptoms.

Although more research is needed to determine how well family therapy helps with borderline personality disorder, studies on other mental disorders show that including family members can help support a person’s treatment. Families and caregivers also can benefit from therapy.

Family therapy helps by:

Allowing the relative or loved one to develop skills to understand and support a person with borderline personality disorder.
Focusing on the needs of family members to help them understand the obstacles and strategies for caring for someone with the disorder.

How can I help a friend or family member with borderline personality disorder?

Here are some ways to help a friend or relative with the disorder:

Take time to learn about the illness to understand what your friend or relative is experiencing.
Offer emotional support, understanding, patience, and encouragement. Change can be difficult and frightening to people with borderline personality disorder, but things can improve over time.
Encourage your loved one in treatment for borderline personality disorder to ask about family therapy.

Seek counseling for yourself. Choose a different therapist than the one your relative is seeing.

How can I learn more about clinical trials studying borderline personality disorder?

NIMH supports a wide range of research, including clinical trials that look at new ways to prevent, detect, or treat diseases and conditions, including borderline personality disorder. Although individuals may benefit from being part of a clinical trial, participants should be aware that the primary purpose of a clinical trial is to gain new scientific knowledge so that others may be better helped in the future.

Researchers at NIMH and around the country conduct clinical trials with patients and healthy volunteers. Talk to a health care provider about clinical trials, their benefits and risks, and whether one is right for you. For more information, visit NIMH’s clinical trials webpage.

5 Facts About "Nervous Bitch Syndrome"

If you are familiar with mental disorders only by hearsay, or, say, from books and Hollywood thrillers, you are in luck. However, you should not flatter yourself - you are much more likely to encounter people who experience serious mental problems than you can imagine, you just don't know about it. Fortunately, most of them are not schizophrenics who secretly make hats out of foil and not maniacs who love to taste human flesh in their spare time.

Many of the inhabitants of our planet suffer from the so-called borderline personality disorder, which is not dangerous for others, but causes many problems for the person himself. We invite you to plunge into the strange, mysterious world of people of the borderline personality type, cruel and heartless, but at the same time - sweet and good-natured.

1. It looks like "Nervous Bitch Syndrome" in the movies

Borderline personality disorder can be diagnosed in the characters of many films, even if the film does not directly talk about it. In some cases, these are thrillers about bloodthirsty psychopaths with obsessive ideas (like "Fatal Attraction" or "Lonely White Woman"), in others - stories of generally normal women who have encountered difficulties in life and are experiencing mental problems (the heroine Jennifer Lawrence in My Boyfriend Is a Crazy, Winona Ryder's character in Girl, Interrupted).

Some people tend to think that almost all psychotic behavior is due to borderline personality disorder. In fact, there are certain criteria that can be considered borderline disorder, first of all, it is an overwhelming fear of loneliness, instability of the self-image and a high level of desocialization.

Just such signs of borderline disorder are shown, for example, by the character of Jennifer Jason Leigh in "The Single White Woman" - she identifies with her flatmate, copies her hairstyle and secretly reads her letters.

People suffering from this mental disorder are impulsive, prone to suicidal behavior, constantly feel a certain “emptyness” and try their best to avoid the real or imagined danger of “being abandoned”.

2. "I hate you, please don't go..."

This phrase perfectly describes the emotional state of individuals with severe borderline personality disorder. Mood swings are very similar to the behavior of teenagers, whom the rampage of hormones makes them either adore everyone around them or hate them wholeheartedly. Every little thing is perceived as an emotionally significant, dramatic turn of events, which radically changes the attitude towards the world. Remember how, at 15 years old, after one bad date, you decided that "no one needs you", "life is over" and "no one understands you"? Borderline sufferers never seem to have passed that age. They change partners quite often and at the same time consider each relationship the "love of their life", which does not prevent them from quarreling with the "ideal" after some time and starting to look for the next one.

One of the reasons for this behavior is the fear of being rejected. Even if the relationship is going well, a person with borderline disorder suffers from obsessive thoughts that sooner or later they will leave him: “He will leave me anyway, it will hurt me ... Therefore, I will leave first!”. Instead of discussing disagreements and looking for compromises together, working on themselves, people of the borderline type blame their own “worthlessness” and “inferiority” for everything.

3. Borderline disorder is not limited to women

Probably, because of the above examples, you got the impression that the borderline personality type occurs only in the fair sex, however, this is not so. Such a misconception is not so unreasonable: according to statistics, among those suffering from borderline disorder, about three-quarters are women, however, many experts consider these data to be quite controversial.

Some psychologists and psychiatrists claim that modern women show signs of borderline personality disorder with banal hysteria. Other scientists talk about the imperfection of diagnostic methods and the "human factor". For example, in the course of one of the experiments, specialists were asked to examine men and women with approximately the same set of symptoms, while doctors more often diagnosed the first with “post-traumatic stress disorder”, and the second with “borderline personality disorder”.

Professor of Harvard University Judith German does not believe at all that it is impossible to speak of borderline personality disorder as a separate mental illness. She calls it one form of post-traumatic stress disorder, citing the fact that the vast majority of people who are diagnosed with a borderline personality type have experienced some kind of severe psychological trauma.

It is worth noting that due to the peculiarities of the human psyche, experts sometimes mistake other mental illnesses for borderline disorder - say, schizophrenia. As a result, the patient does not receive qualified assistance for a long time, his problems worsen and he becomes potentially dangerous to others.

4. There are no effective treatments for borderline disorders

In recent years, medicine has made significant progress in the fight against various bodily diseases. However, what to do with those whose problem is not the Ebola virus and not even cancer, but brain malfunctions that have become an integral part of the personality, modern Hippocrates still do not really know.

In the event that the disease is pronounced and easy to diagnose (say, a person "hears unknown voices"), it is more or less clear to specialists - to isolate from society in a room with soft walls and test various methods of treatment. And if the problems are not so critical? After all, you can’t put people in a madhouse just because a person doesn’t have a single romance that lasts longer than two weeks?

Although in some countries the borderline personality type is one of the most common mental illnesses, few specialists take it seriously. Often, treatment comes down to the fact that the doctor prescribes a psychoactive drug to the patient and sends him home with instructions to turn to him again for "help" when the drug is over.

It should also be mentioned that the therapy is only temporary. Ultimately, almost all patients with a borderline personality type are faced with the fact that it is much cheaper to be treated with pills than to look for good doctors.

5. Vicious circle of misunderstanding and fear

Society is biased against people suffering from borderline disorders - many do not see the difference between similar mental problems and diseases like schizophrenia or manic-depressive psychosis, labeling everyone as "insane". Modern research shows that individuals with a borderline personality type differ from normal people (in psychology and psychiatry, “normal” is generally a rather arbitrary concept) for the most part in that they are extremely suggestible and overly sensitive to the emotional state of others. They are not maniacs, they just pay too much attention to their own and other people's feelings.

Under certain conditions, this disadvantage can be turned into dignity - for example, in the face of a person with borderline disorder, you can find an excellent "vest" to cry on, because such people are able to truly empathize, perceiving someone else's pain as their own. In addition, they are, as a rule, excellent diplomats - if there is such a "crazy" in the company and he is in a good mood, he will provide it to everyone around him, just to get rid of possible negativity.

The problem is that people of the borderline type have two main states, in psychology they are called idealization and devaluation and are referred to as psychological defense mechanisms. In other words, a person can be the personification of positive emotions - to joke, smile and see only good in everything, but in another situation it is as if he is replaced by an evil twin brother, as if covered with invisible thorns, emphatically contemptuous of the whole world and trying to annoy everyone he meets.

You should not be angry at those suffering from such a mental deviation - being in any of their states, they always blame only themselves for what is happening and even hurting others, they feel it, sometimes much stronger than the object of unmotivated aggression itself. That is why there is a high percentage of suicides among people of the borderline type - not everyone is able to live with a constant feeling of guilt and duplicity that frightens himself.
