Causes
As with other mental disorders, the causes of BPD are complex and not fully understood. One finding is a history of childhood trauma, abandonment, abuse or neglect, although researchers have suggested diverse possible causes, such as a genetic predisposition, neurobiological factors, environmental factors, or brain abnormalities.
There is evidence that suggests that BPD and post-traumatic stress disorder (PTSD) are closely related. Evidence further suggests that BPD might result from a combination that can involve a traumatic childhood, a vulnerable temperament and stressful maturational events during adolescence or adulthood.
