概括

DYT-KMT2B dystonia 是渐进的,但异质的. 全球内体 (GPi DBS) 的深度大脑刺激 (DBS) 为移动性提供了长期的好处,特别是当早期开始时.

科学领域:

遗传学遗传学是一种遗传学.
神经学神经学
运动障碍运动障碍

背景情况:

DYT-KMT2B是一种常见的遗传原因,是早期发病的与演变表型相结合的 dystonia.
对于DYT-KMT2B dystonia的GPi DBS的长期结果没有得到很好的描述.

研究的目的:

报告KMT2B变异患者的长期临床过程和GPi DBS结果.
将发现与现有文献进行比较,并为临床管理提供信息.

主要方法:

在两个奥地利中心对9名KMT2B变种患者的前性随访.
收集了六名患者的长期数据 (5-20年).
分析了临床特征和GPi DBS结果,并与已发表的队列进行了比较.

主要成果:

观察到非运动特征 (发育迟缓,智力障碍,) 的频率增加.
所有患者都出现了泛型 dystonia 和 bulbar 干涉,表明疾病进展.
在三名患者中,GPi DBS保持了行走能力,在两名患者中实现了持续的行走恢复,保持了功能独立性.

结论:

DYT-KMT2B dystonia 呈现出一个渐进的但异质的临床过程.
GPi DBS提供了持久的好处,特别是当在行走损失之前启动时.
早期手术干预和多学科护理对于优化长期结果至关重要.

关键词:

在KMT2B中,KMT2B是KMT2B.深度大脑刺激刺激大脑动力障碍性脑麻症脑麻症迪斯托尼亚 (Dystonia) 是一种精神疾病.这是长期的结果.

Electroconvulsive Therapy

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early years,...
