How is Borderline personality disorder (BPD) diagnosed?

Borderline personality disorder (BPD) is diagnosed through comprehensive clinical interviews conducted by mental health professionals, as there are no blood tests or brain imaging scans to identify the condition. A formal diagnosis is based on the criteria established in the DSM-5, which requires a pervasive pattern of instability in interpersonal relationships, self-image, and affects, beginning by early adulthood.

How is a diagnosis of Borderline personality disorder (BPD) made?

There is no single "test" for Borderline personality disorder (BPD). Instead, clinicians use standardized diagnostic interviews to evaluate a patient's history and current behavior. Because the symptoms of Borderline personality disorder (BPD) often overlap with other conditions, the process involves a thorough psychological evaluation to rule out other potential causes for the symptoms.

What are the official diagnostic criteria for Borderline personality disorder (BPD)?

To receive a diagnosis, an individual must meet at least five of the nine criteria outlined in the DSM-5, which include:

• Frantic efforts to avoid real or imagined abandonment.


• A pattern of unstable and intense interpersonal relationships.


• Identity disturbance with a markedly unstable self-image.


• Impulsivity in at least two areas that are potentially self-damaging.


• Recurrent suicidal behavior, gestures, or threats of self-mutilation.


• Chronic feelings of emptiness and inappropriate, intense anger.

Why is the diagnostic journey for Borderline personality disorder (BPD) often difficult?

Many individuals experience a "diagnostic odyssey," often waiting years for an accurate diagnosis due to the stigma surrounding Borderline personality disorder (BPD) and the complexity of its presentation. It is frequently misdiagnosed as Bipolar Disorder, Major Depressive Disorder, or PTSD. We recognize that this process can be deeply invalidating, and the 102 members of the DiseaseMaps community understand the frustration of feeling misunderstood by medical providers.

Which specialists should I consult for Borderline personality disorder (BPD)?

An accurate diagnosis is typically made by a psychiatrist, a clinical psychologist, or a licensed clinical social worker with specialized training in personality disorders. If you feel your current doctor is not well-versed in the nuances of Borderline personality disorder (BPD), seeking a second opinion from a specialist in Dialectical Behavior Therapy (DBT) or personality psychopathology is vital for receiving appropriate care.
