概括
患有疼痛和抑郁症的青少年在杏仁体和额头环等区域显示出明显的脑活动模式. 这些神经差异可能是疼痛和抑郁症的共同疾病的基础.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 医疗成像医学成像
背景情况:
- 青少年伴随性疼痛和抑郁症的神经机制尚不清楚.
- 这项研究调查了青少年经历疼痛和抑郁症的异常大脑活动.
- 这项研究旨在提供神经成像证据,证明大脑在疼痛抑郁症并发症中的作用.
研究的目的:
- 分析和比较青少年的大脑活动,并没有并发性疼痛和抑郁症.
- 为了确定与疼痛-抑郁症并发症相关的特定神经影像标志物.
- 阐明青少年群体中这种常见的并发症的神经基础.
主要方法:
- 休息状态功能磁共振成像 (rs-fMRI) 对三组进行:患有疼痛抑郁并发症的青少年 (n=31),仅患有抑郁症的青少年 (n=26) 和健康对照组 (n=28).
- 参与者完成了汉密尔顿抑郁量表和疼痛视觉模拟量表 (VAS).
- 分析包括低频波动的全脑幅度 (ALFF) 和区域同质性 (ReHo),显著的ALFF区域被用作功能连接分析的种子.
主要成果:
- 与单独患有抑郁症的青少年相比,患有疼痛抑郁症并发症的青少年在右桃体和右中额头环中表现出ALFF增加.
- 在并发症组中,在左中椎,右下椎和右上椎中观察到ALFF的减少.
- 同病组还显示了右侧胰岛的ReHo增加,以及右侧下圈和右角圈之间的功能连接性增加.
结论:
- 患有疼痛抑郁症并发症的青少年在关键大脑区域显示神经元活动和功能连接的改变,包括中前额回环,杏仁体,胰岛,时和叶.
- 这些独特的大脑活动模式表明,疼痛和抑郁症的共患病的潜在神经基础.
- 这些发现强调了在治疗和研究中考虑两个条件的重要性.

Depressive Disorders: Etiology
412
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Cognitive Development During Adolescence
455
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...
