Borderline Personality Disorder

What is Borderline Personality Disorder?

Borderline personality disorder is an illness marked by an ongoing pattern of varying moods, self-image, and behavior. These symptoms often result in impulsive actions and problems in relationships. People with borderline personality disorder may experience intense episodes of anger, depression, and anxiety that can last from a few hours to days.

What are the Symptoms?

People with borderline personality disorder may experience mood swings and display uncertainty about how they see themselves and their role in the world. As a result, their interests and values can change quickly.
People with borderline personality disorder also tend to view things in extremes, such as all good or all bad. Their opinions of other people can also change quickly. An individual who is seen as a friend one day may be considered an enemy or traitor the next. These shifting feelings can lead to intense and unstable relationships.

Other signs or symptoms may include:

• Efforts to avoid real or imagined abandonment, such as rapidly initiating intimate (physical or emotional) relationships or cutting off communication with someone in anticipation of being abandoned
• A pattern of intense and unstable relationships with family, friends, and loved ones, often swinging from extreme closeness and love (idealization) to extreme dislike or anger (devaluation)
• 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 occur primarily during a period of elevated mood or energy, they may be signs of a mood disorder—not borderline personality disorder
• Self-harming behavior, such as cutting
• Recurring thoughts of suicidal behaviors or threats
• Intense and highly changeable moods, with each episode lasting from a few hours to a few days
• Chronic feelings of emptiness
• Inappropriate, intense anger or problems controlling anger
• Difficulty trusting, which is sometimes accompanied by irrational fear of other people’s intentions
• Feelings of dissociation, such as feeling cut off from oneself, seeing oneself from outside one’s body, or feelings of unreality

Not everyone with borderline personality disorder experiences every symptom. Some individuals experience only a few symptoms, while others have many. Symptoms can be triggered by seemingly ordinary events. For example, people with borderline personality disorder may become angry and distressed over minor separations from people to whom they feel close, such as traveling on business trips. The severity and frequency of symptoms and how long they last will vary depending on the individual and their illness.

What are the causes?

The cause of borderline personality disorder is not yet clear, but research suggests that genetics, brain structure and function, and environmental, cultural, and social factors play a role, or may increase the risk for developing borderline personality disorder.

• Family History: People who have a close family member, such as a parent or sibling with the disorder may be at higher risk of developing borderline personality disorder.
• Brain Factors: Studies show that people with borderline personality disorder can have structural and functional changes in the brain especially in the areas that control impulses and emotional regulation. But is it not clear whether these changes are risk factors for the disorder, or 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 adversity during childhood. Others may have been exposed to unstable, invalidating relationships, and hostile conflicts.

Although these factors may increase a person’s risk, it does not mean that the person will develop borderline personality disorder. Likewise, there may be people without these risk factors who will develop borderline personality disorder in their lifetime.

Treatment

Borderline personality disorder has historically been viewed as difficult to treat. But, with newer, evidence-based treatment, many people with the disorder experience fewer or less severe symptoms, and an improved quality of life. It is important that people with borderline personality disorder receive evidence-based, specialized treatment from an appropriately trained provider. Other types of treatment, or treatment provided by a doctor or therapist who is not appropriately trained, may not benefit the person.

Psychotherapy

Psychotherapy is the first-line treatment for people with borderline personality disorder. A therapist can provide one-on-one treatment between the therapist and patient, or treatment in a group setting. Therapist-led group sessions may help teach people with borderline personality disorder how to interact with others and how to effectively express themselves.

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

• Dialectical Behavior Therapy (DBT): This type of therapy was developed for individuals with borderline personality disorder. DBT uses concepts of mindfulness and acceptance or being aware of and attentive to the current situation and emotional state. DBT also teaches skills that can help control intense emotions, reduce self-destructive behaviors, and improve relationships.
• Cognitive Behavioral Therapy (CBT): This type of therapy can help people with borderline personality disorder identify and change core beliefs and behaviors that underlie inaccurate perceptions of themselves and others, and problems interacting with others. CBT may help reduce a range of mood and anxiety symptoms and reduce the number of suicidal or self-harming behaviors.

Medications

Because the benefits are unclear, medications are not typically used as the primary treatment for borderline personality disorder. However, in some cases, a psychiatrist may recommend medications to treat specific symptoms such as mood swings, depression, and other co-occurring mental disorders.

Other Elements of Care

Some people with borderline personality disorder experience severe symptoms and need intensive, often inpatient, care. Others may use some outpatient treatments but never need hospitalization or emergency care.

Therapy for Caregivers and Family Members

Families and caregivers of people with borderline personality disorder may also benefit from therapy. 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.

Some borderline personality disorder therapies include family members, caregivers, or loved ones in treatment sessions. This type of therapy helps by:

• Allowing the relative or loved one develop skills to better 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 borderline personality disorder. Although more research is needed to determine the effectiveness of family therapy in borderline personality disorder, studies on other mental disorders suggest that including family members can help in a person’s treatment.
