Signs & Symptoms of Borderline Personality Disorder

Borderline personality disorder (BPD) is a serious mental health condition that is characterized by significant emotional instability that can lead to a number of stressful mental and behavioral problems. Those with borderline personality disorder tend to struggle with a distorted self-image and often feel as though they are completely worthless or like they are a flawed individual in general. Additionally, those with BPD often display frequent mood swings, of which may include intense anger and impulsive behaviors. And even though people suffering from borderline personality disorder may want to have lasting meaningful relationships, the drastic shifts in mood coupled with frequent anger tend to push others away.

While borderline personality disorder can be a challenging disorder to control, by receiving proper treatment, many individuals with this disorder are able to learn skills to assist in managing and coping with their symptoms and live meaningful lives.

It has been estimated that 1.6% of adults living in the United States have borderline personality disorder. Additionally, borderline personality disorder has shown to be more prevalent in females with 75% of all BPD diagnoses being provided to women.

Causes and Risk Factors of Borderline Personality Disorder

While research is still being conducted to determine what causes the development of borderline personality disorder, most researchers agree that genetic and environmental factors are likely to be involved. These causes and other risk factors are explained in more detail below:

Genetic: Multiple twin studies have shown that borderline personality disorder has a strong genetic component. This means that those who have close relatives who have struggled with this disorder or other mental health conditions are more likely to develop borderline personality disorder themselves. However, a specific gene has yet to be identified.

Environmental: There are a number of environmental factors that can put an individual at an increased risk for the development of borderline personality disorder. For examples, such environmental factors can include poor parenting or a lack of parental involvement. Additionally, individuals who have been subjected to physical, sexual, or emotional abuse and/or neglect are at a higher risk of developing symptoms of borderline personality disorder than are individuals who did not experience similar traumas.

Risk Factors:

  • Family history of borderline personality disorder
  • Family history of other mental health conditions
  • History of physical abuse and/or neglect
  • Exposure to trauma
  • Being female
  • Being a younger adult

If you feel that you are in crisis, or are having thoughts about hurting yourself or others, please call 9-1-1 or go to the nearest emergency room immediately.
