What is borderline personality disorder?
Borderline personality disorder (BPD) is a type of personality disorder, where the person has difficulties in their mood and relationships with others.
It is normal for any person to experience difficult emotions and problems in relationships sometimes, but for the person with BPD this tends to be extreme.
It can be quite hard for a mental health professional to confirm a diagnosis of BPD in children or young people, as they are still developing. But, if the symptoms are persistent at a young age and can only be explained by the BPD criteria, it could possibly be diagnosed.
Causes of borderline personality disorder
There is no specific cause for BPD. It is likely due to a combination of genetics and environmental influences.
People with BPD grow up with different experiences, but a history of trauma and neglect is quite common. These experiences might cause the person to develop unhelpful beliefs about themselves and others around them. These might include:
Feeling invalidated or unsupported as a child
Emotional, sexual, or physical abuse
Losing a parent
Not all people with BPD will have a traumatic history. Some people might still have BPD despite growing up in an environment without stressful situations. For this reason, it is difficult to know exactly what might cause BPD.
