The aim of this study was to investigate serotonin transporter availability in patients with BPD as a marker of the central serotonergic system.Methods: Eight unmedicated patients with BPD and 9 healthy control subjects received single photon emission computed tomography (SPECT) 4 hours after injection of 185 MBq [I-123] ADAM (2-([2-([dimethylamino]methyl)phenyl]thio)). As a measure of brain serotonin transporter (SERT) availability, ratios of specific-to-nonspecific [I-123] ADAM binding for the brainstem and hypothalamus were calculated with an occipital reference. Levels of impulsiveness and depressive symptoms were assessed with the Barratt Impulsiveness Scale and the Beck Depression Inventory.Results: Mean specific-to-nonspecific ratios showed a 43% higher brainstem and a 12% higher hypothalamus ADAM binding in patients, compared with control subjects. We found significant correlations of ADAM binding with both age and impulsiveness but not depression. Associations of BIS scores with ADAM binding remained significant after controlling for age and depression (r = 0.69, p < 0.01).Conclusion: The study provides evidence of a serotonergic dysfunction in patients with BPD and suggests a serotonergic component in the pathophysiology of the disorder. SERT binding reflected the level of impulsiveness as a common feature in BPD. ER -
