概括
对帕金森病 (PD) 的深度大脑刺激 (DBS) 可能会影响冲动控制障碍 (ICD). 在手术后的Globus pallidus pars interna (GPi-DBS) 与下核 DBS (STN-DBS) 相比,显示出更高的ICD严重程度.
科学领域:
- 神经学 神经学
- 神经外科 神经外科
背景情况:
- 冲动控制障碍 (ICD) 是帕金森病 (PD) 治疗的已知并发症.
- 深度大脑刺激 (DBS) 对ICD的影响尚未完全理解,特别是对于不同的刺激目标.
- 之前的研究主要集中在下丘脑核DBS (STN-DBS) 上,使得全球白部分内部DBS (GPi-DBS) 的影响变得不太清楚.
研究的目的:
- 为了比较GPi-DBS和STN-DBS的PD患者中ICD的发病率和严重程度.
- 调查DBS目标与ICD的发展或恶化之间的关系.
主要方法:
- 预计将27名患有PD的个人接受双边DBS (17个STN-DBS,10个GPi-DBS).
- 在手术前进行神经和神经心理评估.
- 后DBS (12-18个月) 评估使用一个缩写的电池和ICD评级尺度.
- 参与者的子集中活化组织体积 (VTA) 的探索.
主要成果:
- 与STN-DBS参与者相比,GPi-DBS参与者在DBS后的ICD严重性得分明显高 (p=0.040).
- 在GPi组中,显著的相互作用表明手术后ICD症状增加 (p=0.015).
- 在DBS后,80%的GPi-DBS和35%的STN-DBS参与者符合ICD标准,独立于莱沃多巴相当的每日剂量.
结论:
- 在帕金森病患者中,GPi-DBS可能与新兴冲动控制障碍的风险增加有关.
- 这些发现表明,DBS目标可能会影响ICD结果.
- 需要进一步研究更大的样本大小,以澄清DBS目标和ICD之间的关系.

Parkinson's Disease: Treatment
1.3K
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.

Parkinson's Disease: Overview
2.3K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...
