Neuropsychological dysfunction in children with borderline personality disorder features: A preliminary investigation

Borderline personality disorder (BPD) is often linked to neuropsychological deficits, yet few studies have examined BPD or its features and concomitant neuropsychological dysfunction in childhood. This study examined children with borderline features (n = 21) using the Coolidge Personality and Neuropsychological Inventory for Children and compared them to controls (n = 21) with features of at least one personality disorder, but not BPD. As hypothesized, the BPD group scored significantly higher than the control group on the Attention Deficit/Hyperactivity Disorder, Executive Functions Deficits, Mild Neurocognitive Disorder, Conduct Disorder. and Oppositional Defiant Disorder scales. It appears that behavioral disturbances associated with BPD are linked strongly with neuropsychological dysfunction. Because none of the children with BPD features in the present sample had a history of traumatic brain injury (TBI), it appears likely that TBI in the histories of adult BPD patients may not be the cause of BPD, but traits such as anger and impulsivity in BPD may cause TBI. Clinical implications and future research directions are discussed. (C) 2000 Academic Press.
