What Is Borderline Personality Disorder?

Borderline Personality Disorder and Genetics

Verywell / Jessica Olah

The exact causes of BPD are not known, but existing research indicates that genetics are a contributing factor.

However, first-degree relatives also share environments, which means that these findings do not point solely to genetics.

Environmental causes, particularly childhood trauma, abuse, and neglect, also contribute to the development of BPD.

That’s why looking at twin studies is helpful in understanding the true genetic contribution to BPD.

Are You Born With BPD or Does It Develop Later?

In some cases, BPD may develop later in life, referred to as late-onset BPD.

For example, triggers could be the loss of loved ones, which might re-trigger fears of abandonment.

Other Risk Factors for BPD

Studies have also found an association between environmental factors and BPD.

Some evidence supports a link between distressing childhood experiences (particularly involving caregivers) and the development of BPD.

However, it is unclear whether these changes cause BPD or if they are a result of BPD.

They often have unstable relationships, pushing away their loved ones while simultaneously experiencing a deep fear of abandonment.

They may also make impulsive and dangerous decisions, increasing their likelihood of substance use.

It used to be believed that BPD was untreatable.

They will learn coping mechanisms to prevent self-harm, maintain relationships, and manage their roller coaster of emotions.

Some people even find that with continuous treatment they no longer meet the diagnostic criteria for BPD.

Unique environmental factors such as abuse, trauma, and neglect are associated with BPD.

Seeking treatment for your own BPD will also support your child’s development.

This can be an asset, as they will likely be diagnosed sooner and get treatment quicker.

Summary

Borderline personality disorder is a complex and serious mental health condition.

While it does have significant genetic factors, the risk of developing BPD is also influenced by environmental factors.

Several therapeutic modalities are effective in treating BPD.
