Borderline Personality Disorder
What is borderline personality disorder?
Borderline personality disorder is a mental illness that severely impacts a person’s ability to manage 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 that can help people manage the symptoms of borderline personality disorder.
How is borderline personality disorder diagnosed?
A licensed mental health professional—such as a psychiatrist, psychologist, or clinical social worker—can diagnose borderline personality disorder based on a thorough evaluation of a person’s symptoms, experiences, and family medical history. A careful and thorough medical exam can help rule out other possible causes of symptoms.
Borderline personality disorder is usually diagnosed in late adolescence or early adulthood. Occasionally, people younger than age 18 may be diagnosed with borderline personality disorder if their symptoms are significant and last at least 1 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 correctly diagnose and treat borderline personality disorder, especially when the disorders have overlapping symptoms. 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 use disorder, or eating disorders.
