概括
大脑[18F]FDG-PET扫描显示出有前途的预测,是否患者与孤立的快速眼动 (REM) 睡眠行为障碍 (iRBD) 将发展帕金森氏症.
科学领域:
- 神经成像和神经学 神经学
- 神经退行性疾病 神经退行性疾病
- 睡眠医学 睡眠医学
背景情况:
- 异形眼睛快速运动 (REM) 睡眠行为障碍 (iRBD) 是像帕金森病 (PD) 和勒维体痴呆症 (DLB) 这样的α-synucleinopathies的前兆标志.
- 从iRBD到PD或DLB的特定表态转换轨迹仍然不确定.
- 基线大脑[18F]FDG-PET成像可能为区分这些进展途径提供了见解.
研究的目的:
- 调查基线大脑[18F]FDG-PET模式在区分iRBD患者中的能力,这些患者最终会转化为PD与DLB.
- 评估这些[18F]FDG-PET模式在iRBD患者的纵向队列中对表转变轨迹的预测能力.
主要方法:
- 从REM睡眠行为障碍 (RBD) 的新生PD和DLBD患者获得特定的[18F]FDG-PET模式 (denovoPDRBD-RP和denovoDLBRBD-RP).
- 将这些衍生模式应用于115名iRBD患者的队列.
- 利用生存分析将[18F]FDG-PET模式与平均随访25.6个月的表转化结果联系起来.
主要成果:
- 在115名iRBD患者中,42人在随访期间进展到明显的α-synucleinopathy (21到PD,21到DLB).
- 无论是denovoPDRBD-RP还是denovoDLBRBD-RP模式都与各自的转换轨迹有显著的关联.
- 大脑 [18F]FDG-PET在iRBD患者中表现出显著的预测能力.
结论:

Alzheimer Disease ll: Pathophysiology
32
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and...

Parkinson Disease ll: Pathophysiology
22
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
