What is borderline personality disorder (BPD)?
It used to be thought people with borderline personality disorder (BPD) were at the ‘border’ between:
- neurosis, where a person is mentally distressed but can still tell the difference between their perception and reality
- psychosis, where a person is unable to tell the difference between their perception and reality, and may experience delusions and hallucinations
Now it is known this is not an accurate description. BPD is best understood as a disorder of mood and interpersonal function (how a person interacts with others).
BPD is a common personality disorder seen by healthcare professionals. Although BPD is said to be more common in women, this is probably because it is recognised less frequently in men, who may be less likely to seek treatment.
