Causes of BPD

There is still some debate over the cause of BPD but most experts believe that BPD develops as a result of biological, genetic and environmental factors.
However, it is important to keep in mind that the exact causes of BPD are not known yet and these are theories that have some research support but are by no means conclusive

Environmental Borderline Personality Disorder Causes

There is strong evidence to support a link between distressing childhood experiences and BPD. The types of experiences that may be associated with BPD include, physical and sexual abuse, emotional or physical neglect, emotional abuse, and parental insensitivity.

It is important to remember, however, that not everyone who has BPD has had these types of childhood experiences and even if a person does have these types of experiences, it does not mean that they will have BPD.

Genetic and Biological Borderline Personality Disorder Causes

Research studies now suggest that 60% of the risk of developing borderline disorder is conveyed by genetics. There is not a single, specific gene for borderline disorder, but there is an increased risk of the disorder being passed on by people who have the disorder itself, or a related disorder, such as bipolar disorder, depression, substance use disorders, ADHD and post traumatic stress disorder.

It appears that no single cause, or risk factor, is responsible by itself for causing the disorder.
