在被监禁的成年和青少年男性样本中,与精神病相关的旁边缘和边缘结构脑异常有牵连。然而,很少有关于女性精神病特征的神经影像学研究,也没有针对被监禁女性青少年的研究。在此,我们首次研究了在最高安全级别监禁的女性青少年样本(N = 39,平均年龄= 17.6岁)中,脑灰质体积与精神病特征之间的关系(使用精神病检查表-青年版[PCL-YV]进行评估)。与男性样本一致,区域灰质体积与女性少年犯的边缘和旁边缘区(包括眶额皮质、海马旁皮质、颞极和左海马)的精神病态特征呈负相关。这些结果提供了证据,证明精神病特征在性别和年龄上表现出相似的神经异常。
Psychopathy-related paralimbic and limbic structural brain abnormalities have been implicated in incarcerated adult and adolescent male samples. However, there have been few neuroimaging studies of psychopathic traits in females in general and no studies from incarcerated female youth in particular. Here we present the first study to examine the relationship between brain gray matter volumes and psychopathic traits (assessed using the Psychopathy Checklist-Youth Version [PCL-YV]) in a sample of maximum-security incarcerated female adolescents (N = 39; mean age = 17.6 years). Consistent with male samples, regional gray matter volumes were negatively related to psychopathic traits in female youth offenders in limbic and paralimbic areas, including orbitofrontal cortex, parahippocampal cortex, temporal poles, and left hippocampus. These results provide evidence that psychopathic traits manifest similar neural abnormalities across sex and age.
