It’s not clear what causes borderline personality disorder, though there are different factors that could lead to a person being diagnosed with BPD. These include:

  • trauma suffered as a child, including neglect, abuse or abandonment
  • genetics – there is some research that suggest you are more likely to receive a diagnosis of BPD if a close family member has it.

There have been some studies on possible causes of BPD, but scientists have differing opinions.

What is important to remember is that this is not your fault. Not at all. Nothing you did, or didn’t do, has led to you being diagnosed with BPD. Often when people are diagnosed with BPD they blame themselves, looking for things they could have done differently. But this is not your fault, and it’s important to remember that.
