概括
宫 dystonia (CD) 患者表现出与年龄相关的状体积的独特增加,与经历衰退的健康个体不同. 这一发现突出了与其他焦点 dystonias 相比,CD 中不同的神经生物学机制.
科学领域:
- 神经成像是一种神经成像.
- 神经学 神经学
- 神经科学是一个神经科学.
背景情况:
- 在孤立的,异形性 dystonia 的状体积差异是不一致的.
- 健康的衰老涉及渐进的条形体积损失.
- 成年开始的宫 dystonia (CD) 和其他焦点 dystonias 的年龄相关的条纹体积变化仍然不清楚.
研究的目的:
- 为了研究与成人开始的宫 dystonia (CD) 和其他孤立的,异常的焦点 dystonias 的参与者的年龄相关的条纹体积差异.
- 为了比较CD患者,其他类型的 dystonia 亚型和健康对照之间的年龄相关的条形状体积轨迹.
主要方法:
- 在184名参与者中分析了高分辨率结构性MRI (92名焦点 dystonia,92名对照).
- 使用FreeSurfer量化的皮下体积 (尾皮体,皮体,海马体,杏仁体,心室),调整为内体积.
- 线性回归检查了年龄与体积的关系,控制性和运动.
主要成果:
- 与对照人群相比,宫性 dystonia (CD) 呈现出与年龄相关的显著不同的条形状体积轨迹.
- 布塔门和尾状体积显示出显著的群体×年龄相互作用,CD显示体积增加,对照显示下降.
- 其他类型的 dystonia 亚型显示与年龄相关的衰退类似于对照组;只有 CD 显示保存的 putamen 和 caudate 卷.
结论:
- 随着年龄的增长,尾状膜和膜体积的选择性保存是宫 dystonia (CD) 在焦点 dystonia亚型中独有的.
- 这种神经解剖学上的区别表明,CD背后存在着不同的适应性或病理生理机制.
- 对 dystonia亚型的研究需要特定年龄的方法来理解异质的神经生物学基质.

Parkinson's Disease: Treatment
970
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

Skeletal Muscle Relaxants: Therapeutic Uses
880
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...
