What Causes Borderline Personality Disorder?

The etiology of borderline personality disorder remains to be unknown. The combinations of biological, environmental and genetic factors are attributed to the development of borderline personality disorder are as follow: 2

  • Genes

There are studies pointing out genetic and heredity factors as the main causes of the development of borderline personality disorder.

  • Defects on brain.

Researchers are finding that structural brain defects can cause changes in one’s emotions and behavior that can trigger them to become aggressive and compulsive.

Dysfunctional brain chemistry involving the neurotransmitters dopamine, serotonin, acetylcholine, and norepinephrine can cause variability in moods and emotional changes.

  • Environmental factors.

A person who has a very stressful childhood may develop borderline personality disorder. Sexual abuse, abandonment, and separation are just some of the issues that can predispose someone to the development of a borderline personality disorder.
