概括
大脑深度刺激 (DBS) 提供了一个安全有效的治疗方法. 这项研究显示了稳定,长期的症状改善,这表明Vim DBS可以作为白色DBS的替代品.
科学领域:
- 神经学
- 神经外科
- 运动障碍
背景情况:
- 静脉震是静脉震的一个具有挑战性的表现, 治疗选择有限.
- 经过深度大脑刺激 (DBS) 的内球被确立为 dystonia,但其对 dystonic tremor 的有效性仍有争议.
- 塔拉米DBS已被用于极端 dystonic震,但头部震的经验很少.
研究的目的:
- 评估腹中介 (Vim) 核DBS的长期疗效和安全性.
- 评估Vim DBS对震严重程度和与 dystonia相关的残疾的影响.
主要方法:
- 十八名患有主要的性头的患者在Vim核中植入四极DBS电极.
- 使用伯克- 法恩- 马斯登 dystonia 评分表 (BFMDRS) 运动和残疾评分,以及修改后的法恩- 托洛萨- 马林震动评分表 (mFTMTRS) 来评估症状的严重程度.
- 评估是在手术前,短期随访 (3 个月2 年) 和长期随访 (> 2 年) 进行的.
主要成果:
- 在Vim DBS后,震和 dystonia分数均有显著改善.
- 在长期随访中,震动得分从手术前的7. 94降至1. 71 (P < 0. 001).
- 在长期随访中,BFMDRS运动分数从14. 56提高到7. 0;BFMDRS残疾分数从3. 88提高到2. 71 (分别P< 0. 001和P< 0. 05).
结论:
- 泰拉米克Vim核DBS是一种安全有效的治疗方法,证明了长期的益处.
- Vim DBS提供了一种可行的替代DBS,特别是当头部震是主要症状时.
- 这项研究支持Vim DBS作为治疗耐火性脑震的有价值的选择.

Long-term Depression
27.3K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Longitudinal Research
11.7K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Clinical Trials
8.5K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Clinical Trials: Overview
4.7K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Bioavailability Study Design: Healthy Subjects Versus Patients
248
Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Longitudinal Studies
706
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
