Symptoms

Borderline personality disorder

Symptoms may include:

  • A strong fear of abandonment. This includes going to extreme measures so you're not separated or rejected, even if these fears are made up.
  • A pattern of unstable, intense relationships, such as believing someone is perfect one moment and then suddenly believing the person doesn't care enough or is cruel.
  • Quick changes in how you see yourself. This includes shifting goals and values, as well as seeing yourself as bad or as if you don't exist.
  • Periods of stress-related paranoia and loss of contact with reality. These periods can last from a few minutes to a few hours.
  • Impulsive and risky behavior, such as gambling, dangerous driving, unsafe sex, spending sprees, binge eating, drug misuse, or sabotaging success by suddenly quitting a good job or ending a positive relationship.
  • Threats of suicide or self-injury, often in response to fears of separation or rejection.
  • Wide mood swings that last from a few hours to a few days. These mood swings can include periods of being very happy, irritable or anxious, or feeling shame.
  • Ongoing feelings of emptiness.
  • Inappropriate, strong anger, such as losing your temper often, being sarcastic or bitter, or physically fighting.

How neuroscience is contributing to our understanding of how BPD develops.

What Causes Borderline Personality Disorder?

  • Genetics plays a larger role in the development of BPD than previously thought.
  • The brains of people diagnosed with BPD are significantly different from normal brains.
  • Moderate to high functioning people with BPD rarely get diagnosed or included in research studies.
  • We do not yet know whether higher functioning people with BPD have an equally high genetic component.

Medication

Borderline personality disorder

Medications

Although no drugs have been approved by the Food and Drug Administration specifically for the treatment of borderline personality disorder, certain medications may help with symptoms or co-occurring problems such as depression, impulsiveness, aggression or anxiety. Medications may include antidepressants, antipsychotics or mood-stabilizing drugs.

Hospitalization
At times, you may need more-intense treatment in a psychiatric hospital or clinic. Hospitalization may also keep you safe from self-injury or address suicidal thoughts or behaviors.

Recovery takes time Learning to manage your emotions, thoughts and behaviors takes time. Most people improve considerably, but you may always struggle with some symptoms of borderline personality disorder. But treatment can improve your ability to function and help you feel better about yourself
