Few studies have focused on neurobiological mechanisms that may underlie Borderline Personality Disorder (BPD) and BPD symptoms with inconsistent results. An approach that has not been examined is whether impulsivity in BPD is related to a BPD individual's poor decision-making skills due to deficits in the somatic marker system (Damasio, 1994). Somatic marker system refers to a complex circuit involving cortical and subcortical areas of the brain that are implicated in the way people make decisions by "gut instinct." Deficits in the somatic marker system explain one's inability to make good decisions because of his or her insensitivity to future negative consequences. The present study investigated mean differences between 43 individuals with BPD and 26 normal controls on decision-making skills measured by the Bechara gambling task (BGT; Bechara, Damasio, Damasio, & Anderson, 1994), the Stroop Color-Word Naming Test as a classic laboratory measure of impulsivity, and a self-reported measure of impulsivity, the Barratt Impulsiveness Scale, 11th Ed. (BIS-11; Patton, Stanford, & Barratt, 1995). The severity of BPD disorder measured by Global Assessment of Functioning (GAF; American Psychiatric Association, 2000) was correlated with BGT and Stroop performances in BPD patients. The relationships between the Stroop Test and BGT were examined. Results showed that there were no group differences in BGT decision-making performance or in Stroop performance. While there were significant differences between individuals with BPD and controls in BIS-11 total and subscale scores, the scores did not significantly correlate with BGT or Stroop performance. Full scale IQ appeared to be related to BGT performance as well as BIS-11 scores and GAF. Neurocognitive measures used in this study did not account for the impulsiveness in the BPD group. Research and clinical implications of these findings are discussed.
