How is borderline personality disorder diagnosed?
There is no test for BPD. It can only be diagnosed by a mental health professional after talking to the person and getting to know them.
The diagnosis of BPD can be made if a person has several of the signs or features. There are many combinations of these features, so people with a diagnosis of BPD can seem very different from one another.
If someone has signs of BPD, their doctor or psychologist will carefully ask questions about their life, experiences and symptoms before making the diagnosis. It could take more than one session to be sure of the diagnosis, because some of the symptoms of BPD are similar to the symptoms of other mental health conditions.
BPD is usually not diagnosed in children before puberty.
How is borderline personality disorder treated?
Psychological treatments (talking therapies) are the best way to treat BPD. These treatments usually involve talking with a health professional one-to-one, or sometimes attending special groups.
Medication is not recommended as a person’s main treatment for BPD.

Recovery from borderline personality disorder
With treatment, most people with BPD recover from their symptoms for at least some of the time. If someone recovers there’s a good chance they won’t develop symptoms again.
Most people find that their symptoms improve within a few years after getting the diagnosis.
Many people achieve a good social life and work life. Some people still have some problems with work and social life, even though their symptoms have improved.
