概括
阻塞性睡眠呼吸暂停 (OSA) 的严重程度与血中的阿尔茨海默病 (AD) 生物标志物有关. 将OSA严重程度与血氨基酸β (Aβ) 结合起来,可以更好地检测AD病理.
科学领域:
- 神经学 神经学
- 睡眠医学 睡眠医学
- 生物标志物研究 生物标志物研究
背景情况:
- 阻塞性睡眠呼吸暂停 (OSA) 越来越多地被认为对神经退行性疾病的潜在影响.
- 了解OSA严重程度和阿尔茨海默病 (AD) 生物标志物之间的关系对于早期检测和干预至关重要.
研究的目的:
- 调查OSA严重程度与AD的血生物标志物之间的关联.
- 为了确定OSA的严重程度,独立或与大脑脊髓液 (CSF) 粉样蛋白,与AD生物标志物相关.
- 评估与OSA严重程度相结合的血氨基酸β (Aβ) 42/Aβ40是否可以提高氨基酸粉症和病理的检测.
主要方法:
- 分析了120名认知正常的老年人 (70名具有CSF数据).
- 使用呼吸暂停/呼吸暂停指数量化OSA严重程度.
- 血Aβ40,Aβ42,tau和神经纤维光链 (NfL) 用单分子阵列测量;通过ELISA测量CSF粉样蛋白和tau.
- 统计分析包括调整的相关性,概括模型和接收器运行特征分析.
主要成果:
- OSA严重程度与血Aβ40 (r=0.21),Aβ42 (r=0.26) 和Aβ42/Aβ40比率 (r=0.20) 有显著的相关性.
- /NfL与OSA严重程度之间的关联取决于CSF-Aβ42水平.
- 结合OSA严重程度和血Aβ42 / Aβ40的组合改善了CSF氨基粉症 (AUC=0.78) 和tau病理 (AUC=0.71) 的检测.
结论:
- OSA的严重程度与血粉样蛋白β水平升高有关.
- 结合OSA严重程度和血生物标志物,特别是Aβ42/Aβ40,有助于非侵入性检测AD相关病理.
- 这些发现突显了将睡眠呼吸暂停评估与血生物标志物分析相结合的潜力,以改善AD检测.

Alzheimer's Disease: Overview
1.9K
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...

Alzheimer's Disease: Treatment
1.1K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Sleep Apnea
670
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Dementia

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
