Etiology of Borderline Personality Disorder
Borderline personality disorder is defined as a mental illness that involves unstable moods, behavior and relationships. There are many other symptoms of borderline personality disorder, some of which include intense irritability, elevated levels of fear, and anger. The etiology of BPD is unknown, but through a number of different studies it is believed that it can be caused by genetics, environmental factors, and/or brain abnormalities. Scientists continue to study genes that help regulate both emotions as well as impulse control for possible links to BPD.
It has not been proven that borderline personality disorder is caused by genetics because there in not a single specific gene that causes it. There are, however, numerous studies that suggest BPD is possibly inherited and that there may be a link between BPD and other mental illness experienced by family members. There is an increased risk factor for BPD if family members have BPD or related disorders such as ADHD, posttraumatic stress disorder, and bipolar disorder. There are also studies that indicate that impulsive aggression is inherited, but serotonin related genes only have an effect on an individual’s behavior. An increased risk factor in heritability for BPD can also be caused if impulsive aggression and affective impulsivity are phenotypes. A study was done to see if there is a correlation between borderline personality disorder and mood disorders. Results
