Curr Biol:与精神疾病相关的童年特质

2017-11-29 佚名 大话精神

发表在Current Biology上的一项研究发现,具有精神病倾向的男孩报告的愿望较少;与大多数儿童和成年人不同,处于精神病风险的男孩不会觉得笑声具有很强的传染性。大脑扫描也显示他们对其他人的笑声反应较低。

发表在Current Biology上的一项研究发现,具有精神病倾向的男孩报告的愿望较少;与大多数儿童和成年人不同,处于精神病风险的男孩不会觉得笑声具有很强的传染性。大脑扫描也显示他们对其他人的笑声反应较低。

人类的笑声涉及促进社会互惠和情感共鸣的大脑区域,能促进亲和力和社会凝聚力。那些发展为精神疾病风险最高的人显示出对前脑岛笑声的神经反应减弱,这个区域涉及到听觉运动处理,并将行为倾向与情绪体验和主观感受联系起来。

研究作者Essi Viding教授说:“把精神病患者贴上标签是不恰当的,精神病是一种成人人格障碍。然而,纵向研究发现,某些儿童发展为精神病的风险较高,因此我们筛选了具有这种风险的特征。”

无情和冷漠与日后发展精神病有关。那些有这种特质的孩子,连同破坏性的行为,都是那些不愿意和别人一起欢笑的人。扫描显示,他们的大脑也以不同的方式工作,他们大脑相关区域及活动减少。

Viding教授说,有发展精神病风险的孩子以与我们其他人不同的方式体验世界,但这并不意味着这些孩子注定成为反社会或危险的;相反,这些发现揭示了为什么他们经常做出不同于其他人的选择。

该研究结果可归结为以下几点:

精神病性症状与缺乏持久的亲属关系有关;

聆听人类的笑声,能促使大脑区域进行情感共鸣;

处于精神疾病风险的男孩已经减少了对笑声的神经/行为反应;

笑声的非典型处理可能反映了减少社会联系的机制。
