Borderline Personality Disorder Basics
Borderline Personality Disorder: Risk Factors
BPD is more common among those who have first-degree relatives with the disorder. Experts call it a biosocial disorder because it is the result of two distinct factors, biological and social. The biological factor in BPD is a temperament that is highly emotionally reactive, quick to get very upset and slow to return to baseline. The social factor is being raised in an environment that does not validate those intense emotions in childhood, either through neglect or ordinary parenting practices that dismiss extreme emotions as overreactions. Without that validation from adults, children may not develop effective skills in emotional regulation, and may instead resort to unhealthy ways of coping with their feelings.
