Novelty seeking (NS) and antisocial personality (ASP) are commonly exhibited by those who suffer from addictions, such as substance abuse. NS has been suggested to be a fundamental aspect of ASP. To investigate the neurobiological substrate of NS and ASP, we tested the relationship between regional cerebral glucose metabolism and the level of NS, determining the differences between individuals with and without ASP. Seventy-two healthy adults (43 males, mean age±SD=38.8±16.6 years, range=20~70 years; 29 females, 44.2±20.1 years, range=19~72 years) underwent resting-state brain positron emission tomography (PET) 40 minutes after (18)F-fluorodeoxyglucose (FDG) injection. Within 10 days of the FDG PET study, participants completed Cloninger's 240-item Temperament and Character Inventory (TCI) to determine NS scores. Participants with and without ASP were grouped according to their TCI profiles. Statistical parametric mapping analysis was performed using the FDG PET and TCI profile data. NS scores positively correlated with metabolism in the left anterior cingulate gyrus and the insula on both sides of the brain and negatively correlated with metabolism in the right pallidum and putamen. Participants with ASP showed differences in cerebral glucose metabolism across various cortical and subcortical regions, mainly in the frontal and prefrontal areas. These data demonstrate altered regional cerebral glucose metabolism in individuals with NS and ASP and inform our understanding of the neurobiological substrates of problematic behaviors and personality disorders.

新颖性寻求和反社会人格中的区域性脑葡萄糖代谢:正电子发射断层扫描研究。

诸如药物滥用之类的成瘾症患者通常会表现出寻求新奇(NS)和反社会人格(ASP)的能力。NS被认为是ASP的基本方面。为了研究NS和ASP的神经生物学底物,我们测试了局部脑葡萄糖代谢与NS水平之间的关系,确定了有和没有ASP的个体之间的差异。七十二名健康成人(男43名,平均年龄±SD = 38.8±16.6岁,范围= 20〜70岁;女29名,44.2±20.1岁,范围= 19〜72岁)接受了静息状态的脑正电子发射断层显像( PET)(18)F-氟脱氧葡萄糖(FDG)注射后40分钟。在FDG PET研究的10天内,参与者完成了Cloninger的240个项目的气质和性格量表(TCI),以确定NS得分。有和没有ASP的参与者根据他们的TCI配置文件进行分组。使用FDG PET和TCI配置文件数据进行统计参数映射分析。NS评分与左前扣带回和大脑两侧的岛状岛的代谢呈正相关,而与右侧苍白球和壳状核的代谢呈负相关。患有ASP的参与者在各个皮质和皮质下区域(主要在额叶和额叶前区域)显示出大脑葡萄糖代谢的差异。这些数据证明了患有NS和ASP的人的局部脑葡萄糖代谢发生了改变,并为我们对问题行为和人格障碍的神经生物学底物的理解提供了信息。使用FDG PET和TCI配置文件数据进行统计参数映射分析。NS评分与左前扣带回和大脑两侧的岛状岛的代谢呈正相关,而与右侧苍白球和壳状核的代谢呈负相关。患有ASP的参与者在各个皮质和皮质下区域(主要在额叶和额叶前区域)显示出大脑葡萄糖代谢的差异。这些数据证明了患有NS和ASP的人的局部脑葡萄糖代谢发生了改变,并为我们对问题行为和人格障碍的神经生物学底物的理解提供了信息。使用FDG PET和TCI配置文件数据进行统计参数映射分析。NS评分与左前扣带回和大脑两侧的岛状岛的代谢呈正相关,而与右侧苍白球和壳状核的代谢呈负相关。患有ASP的参与者在各个皮质和皮质下区域(主要在额叶和额叶前区域)显示出大脑葡萄糖代谢的差异。这些数据证明了患有NS和ASP的人的局部脑葡萄糖代谢发生了改变,并为我们对问题行为和人格障碍的神经生物学底物的理解提供了信息。NS评分与左前扣带回和大脑两侧的岛状岛的代谢呈正相关,而与右侧苍白球和壳状核的代谢呈负相关。患有ASP的参与者在各个皮质和皮质下区域(主要在额叶和额叶前区域)显示出大脑葡萄糖代谢的差异。这些数据证明了患有NS和ASP的人的局部脑葡萄糖代谢发生了改变,并为我们对问题行为和人格障碍的神经生物学底物的理解提供了信息。NS评分与左前扣带回和大脑两侧的岛状岛的代谢呈正相关,而与右侧苍白球和壳状核的代谢呈负相关。患有ASP的参与者在各个皮质和皮质下区域(主要在额叶和额叶前区域)显示出大脑葡萄糖代谢的差异。这些数据证明了患有NS和ASP的人的局部脑葡萄糖代谢发生了改变,并为我们对问题行为和人格障碍的神经生物学底物的理解提供了信息。
