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.
- 认知科学 认知科学
背景情况:
- 低于值的抑郁症 (StD) 是发展主要抑郁症 (MDD) 和经历自杀倾向的重要危险因素.
- 在这些条件下,自杀倾向可能与痛苦不容忍和取决于背景的应对策略有关.
- 了解执行功能的神经支对于识别有风险的个体和制定有针对性的干预措施至关重要.

- 调查与性病,MDD和健康对照 (HC) 组之间与执行功能相关的大脑网络组织的差异.
主要方法:
- 磁共振成像 (MRI) 用于扫描79名年轻成年人 (27名StD,30名MDD,23名HC).
- 神经认知评估包括空间工作记忆,视觉处理速度和响应抑制 (例如,OTSMLC5,SWMBE,RVPA',SSTSSRT) 的测量.
- 计算了全球和区域图表指标 (中心度,中间中心度,自向中心度) 来分析rs-FCN枢纽.
主要成果:
- 全球网络指标在所有组 (StD,MDD,HC) 中都是可比的.
- 区域图表指标的显著差异在包括左背前胰岛 (dAI) 和右背中前额叶皮质 (dmPFC) 在内的枢纽中观察到.
- 在右dmPFC和空间工作记忆 (SWMBE),左dAI和响应抑制/视觉处理 (SSTSSRT,RVPA') 之间发现了关联,以及与自杀意念的胸膜中心性.
结论:
- Salience和thalamic网络与STD和MDD中的空间战略,规划,响应抑制和自杀性有关.
- 执行功能缺陷和 salience-thalamic 网络连接的改变是这些情况的关键特征.
- 抗自杀疗法应该考虑向执行功能和调节患有STD和MDD的个体的突出-thalamic网络.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
