It’s important to note that not all people with this disorder will exhibit the same symptoms. So called ‘quiet BPD’ can be difficult to identify because the symptoms are less overt than in classic cases of the disorder. Additionally, because of the stigma around Borderline Personality Disorder, some may go undiagnosed for many years or be misdiagnosed with Bipolar Disorder or Schizophrenia.
People who are at risk of this condition may have a family with a history of borderline personality disorder, brain factors like structural or functional changes in the brain, or be subjected to cultural, social, or environmental factors like trauma, abuse, abandonment, or hostile conflicts.
