概括
终身早泄 (PE) 涉及与自我处理和抑制相关的网络中的大脑灰质体积 (GMV) 异常. 这些结构变化与神经递质系统的改变相关,为PE病理提供了洞察力.
科学领域:
- 神经成像是一种神经成像.
- 男人的性功能障碍是男性的性功能障碍.
- 计算精神病学是一种计算精神病学.
背景情况:
- 终身早泄 (PE) 是一个普遍存在的男性性功能障碍.
- 之前关于PE相关大脑结构的单变量研究产生了不一致的结果.
研究的目的:
- 在终身PE患者中调查结构性大脑异常.
- 探索与PE相关的神经递质配置文件的潜在变化.
- 为了确定PE分类的关键成像特征.
主要方法:
- 利用了47名终身PE患者和34名健康对照的T1加权MRI数据.
- 应用基于源的形态测量来将灰色物质体积 (GMV) 地图分解为独立的组件.
- 采用沙普利增材解释 (SHAP) 进行特征重要性和空间关联分析,用于结构-神经递质相关性.
主要成果:
- 在终身PE患者的默认模式网络,前额叶和叶中发现了显著的GMV异常.
- SHAP分析强调了GMV组件IC22,IC25和IC1作为分类的关键预测因素.
- 在GMV异常与血清激素,多巴胺激素,GABA激素,谷氨酸激素和诺亚激素系统之间发现的相关性.
结论:
- 在终身PE中使用多变量分析和SHAP解释性来证明结构-神经递质关联.
- 研究结果表明,GMV异常与自我参考处理和射精控制缺陷有关.
- 为制定针对终身PE的有针对性的治疗策略提供了基础.

776
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....

Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
