概括
对阿尔茨海默氏症 (AD) 粉样蛋白病理学的新血液检测可以改善诊断. 这种非侵入性测试可以减少障碍,简化护理,并加速患者的治疗开始.
科学领域:
- 神经学 神经学
- 生物标志物发现发现
- 医疗保健管理的管理
背景情况:
- 预计阿尔茨海默病 (AD) 的疾病修饰疗法 (DMT) 的出现将大大增加对诊断测试的需求.
- 非侵入性基于血液的生物标志物 (BBBM) 测试有望检测粉样蛋白β病理,潜在地降低诊断障碍,并促进及时启动DMT.
研究的目的:
- 为了研究当前阿尔茨海默病护理途径的变化.
- 评估基于血液的生物标志物测试在优化AD诊断和护理方面的潜在作用.
主要方法:
- 在美国,中国,英国,德国,西班牙和法国的213名医疗保健专业人员和付费者中进行了一项调查.
- 两次咨询委员会会议在美国和欧洲举行,以收集专家的见解.
主要成果:
- 目前的AD诊断途径表现出显著的异质性,导致一些患者的诊断错误,而另一些患者则不必要的手术.
- 确认性粉样蛋白检测 (脑脊液生物标志物或正子辐射断层扫描) 的使用是有限的,导致诊断和治疗延迟.
- 具有高负预测值的BBBBM测试可以简化诊断,减少低风险个体的不必要程序,并在必要时指导确认测试.
- 即将批准的DMT需要快速可靠的AD诊断解决方案.
结论:
- 准确,非侵入性和用户友好的BBBBM测试粉样蛋白病理学可以作为指导诊断程序和转诊的关键工具.
- 这种测试有可能显著简化粉样蛋白病理的早期诊断,并加速启动疾病修饰疗法.

Alzheimer's Disease: Overview
494
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
195
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...
