People affected by Borderline Personality Disorder (BPD) frequently experience distressing emotional states, difficulty in relating to other people, and self-harming behaviour.

It is estimated that between two and five per cent of the population are affected by BPD at some stage in their lives. The symptoms of the disorder usually first appear in mid to late teens or in early adulthood. Women are three times more likely to be diagnosed with BPD than men.

The causes of BPD are not fully understood and are most likely to be a combination of biological and life factors. It is thought that many people with BPD have experienced abuse, trauma or neglect during childhood, and that this may have contributed to the development of the disorder.

As with all mental illnesses, early diagnosis and effective treatment improve the outcomes for people with BPD.
