概括
帕金森病主观认知衰退 (PD-SCD) 的认知衰退与脑脊液 (CSF) 的β-粉样蛋白水平有关. 低CSF Aβ42和生物阿尔茨海默氏症 (AD) 亚组显示认知能力下降速度更快,痴呆风险增加.
科学领域:
- 神经科学是一个神经科学.
- 生物标志物 生物标志物
- 神经退行性疾病 神经退行性疾病
背景情况:
- 帕金森病主观认知衰退 (PD-SCD) 呈现出异质的认知进展.
- 识别患有恶化风险较高的患者对于有效管理至关重要.
- 大脑脊髓液 (CSF) 生物标志物可以提供对PD-SCD认知轨迹的见解.
研究的目的:
- 调查CSF生物标志物与PD-SCD患者认知衰退之间的关联.
- 根据CSF生物标志物概况识别不同的认知轨迹.
- 探索CSF生物标志物对PD-SCD痴呆风险的预测价值.
主要方法:
- 利用了来自帕金森病进展标记计划 (PPMI) 队列的数据.
- 包括PD-SCD患者的基线CSFβ-粉样蛋白 (Aβ42) 和酸化 (p-tau181) 水平.
- 使用蒙特利尔认知评估 (MoCA) 评估纵向认知功能.
主要成果:
- 五名患者符合生物阿尔茨海默病 (AD) 的标准,表现出加速的MoCA衰退.
- 较低的基线CSFAβ42水平与更快的MoCA下降显著相关.
- 三个基于CSF的子组 (正常Aβ42,低Aβ42,生物AD) 显示认知结果逐渐恶化,痴呆风险增加.
结论:
- 基线CSF Aβ42水平是PD-SCD认知进展的重要预测指标.
- 脑液生物标志物分析确定了不同的认知轨迹,具有不同的痴呆风险.
- 这些发现支持在PD相关认知衰退的临床试验中使用CSF生物标志物进行患者分层.

Alzheimer's Disease: Overview
451
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
