Borderline personality disorder is diagnosed by a psychologist, psychiatrist, clinical social worker, or other mental health professional. The disorder is a type of "Cluster B" personality disorder, which are chronic conditions characterized by unstable and dysfunctional behaviors that affect one's relationships with others. People with BPD often have co-existing mental conditions, such as depression, anxiety, PTSD, or substance abuse.

Borderline personality disorder is known to develop and become present during adolescence, however, mental health providers rarely diagnose anyone under the age of 18 with BPD. Mental health providers analyze behaviors, family history, and discuss symptoms with their patients, which may lead to a diagnosis using the DSM-5 criteria for BPD.

Borderline personality disorder is treated with psychotherapy and oral medications. Forms of therapy like dialectical behavior therapy (DBT) and cognitive behavioral therapy (CBT) can help people with BPD identify self-destructive attitudes and harmful behaviors, which they may then be able to manage or change. Group therapy is another treatment option which may improve people with BPD's ability to share their emotions and to promote positivity. Psychiatrists may prescribe patients antidepressants and/or anxiety medications such as Prozac (fluoxetine), Wellbutrin (bupropion), and Zoloft (sertraline). Some patients may receive antipsychotic drugs which can help stabilize mood and reduce impulsivity.

With consistent treatment, people with BPD are able to recognize and prevent destructive behaviors and mood swings, typically by changing their patterns of thought. Many people with borderline personality disorder are able to live successful and healthy lives.
