概括
功能磁共振成像 (fMRI) 预测了帕金森病 (PD) 中的深度大脑刺激 (DBS) 结果,比单独的临床因素更好. 这种脑成像方法可以改善患者选择和对DBS治疗的监测.
科学领域:
- 神经成像是一种神经成像.
- 运动障碍 运动障碍
- 生物标志物发现发现
背景情况:
- 深度大脑刺激 (DBS) 提供了帕金森病 (PD) 运动缺陷的症状缓解,但结果在患者之间有很大差异.
- 目前对DBS成功的临床预测指标是不可靠的,只能解释结果变化的很小一部分.
- 对于可靠的生物标志物,如从功能磁共振成像 (fMRI) 衍生出来的生物标志物,对于提高DBS结果的预测准确性至关重要.
研究的目的:
- 调查手术前休息状态fMRI衍生的运动网络连接的实用性,作为预测PDDBS治疗结果的生物标志物.
- 确定基于fMRI的连接措施是否可以提高现有临床因素的预测能力.
- 评估fMRI特征在区分PD与亨廷顿病和健康对照中的特异性.
主要方法:
- 对120名PD患者的休息状态fMRI数据的回顾性分析,这些患者接受了DBS治疗,准了亚thalamic核或白色球体.
- 运动网络连接的计算和临床预测因素的提取 (年龄,性别,目标,半球,药物反应).
- 回归和分类分析,以评估单独的fMRI特征和与临床因素结合的预测价值,并评估诊断特异性.
主要成果:
- 与临床预测因素相结合的fMRI特征,与单独的临床预测因素相比,解释了显著更多的结果差异 (调整R2=0.36).
- 五个特定的皮质 - 基底 - 大脑网络连接对预测了DBS结果,并与对照组和亨廷顿病区分了PD,分别准确率为67%和73%.
- 探索性分析表明,脑内连接性显著提高了PD分类准确性 (≥98%),尽管它对DBS结果的预测因素不那么稳定.
结论:
- 从fMRI获得的患者特定的运动网络连接显著提高了对帕金森病中DBS结果的预测.
- 这些发现表明,基于fMRI的生物标志物可以帮助检测和监测基底腺的疾病.
- 未来的研究应该集中在验证和扩展这些模型用于多参数MR预测,以开发用于DBS治疗的临床决策支持工具.

Role of Cerebellum and Prefrontal Cortex in Memory
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the cerebellum's...
Psychosurgery
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
