What causes Borderline Personality Disorder
Both social and genetic factors play a role in the development of Borderline Personality Disorder. Using hi-tech imaging devices provides researchers with an intimate look inside the brain. Studies suggest that about 60% of the risk for developing BPD is due to physical abnormalities in the structure of the brain. These abnormalities affect the proper functioning of brain circuits that control emotional processing, impulse control and cognitive abilities like perception and reasoning.
In addition to the role of genetics, negative social interactions like exposure to a turbulent environment at home, work, or among peers increase the risk for the development of the BPD. The intertwining of biological and social factors is referred to as the Biosocial Model. Of all the social factors influencing the development of borderline personality disorder, extreme family difficulties are the most common.
