概括
这项试点研究表明,使用达沙替尼和奎尔塞丁的老化疗法对于早期阿尔茨海默病 (AD) 是安全的和可行的. 达沙提尼布进入了中枢神经系统,这表明AD治疗的潜力.
科学领域:
- 神经科学是一个神经科学.
- 老年学是一门学科.
- 药理学 药理学是指药理学的学科.
背景情况:
- 细胞衰老与阿尔茨海默氏症 (AD) 病原发生有关.
- 老化疗法旨在清除老化的细胞,为AD提供了潜在的治疗策略.
研究的目的:
- 评估口服老化疗法 (达沙替尼和奎尔塞丁) 的安全性,可行性和中枢神经系统 (CNS) 透性,用于早期症状阿兹海默症患者.
- 探索与阿尔茨海默病老化治疗相关的初步疗效和生物标志物变化.
主要方法:
- 一个开放的,I期临床试验,涉及五名早期症状AD参与者.
- 参与者接受了12周的口服达沙替尼和奎尔塞丁.
- 在血液和脑脊液 (CSF) 中评估药物水平,安全性,耐受性,认知功能,神经成像和CSF生物标志物.
主要成果:
- 达沙替尼证明了中枢神经系统的透性,在脑脊液 (80%的参与者) 中可检测到水平. 在CSF中没有检测到Quercetin.
- 治疗耐受性良好,没有早期停止治疗,支持有利的安全性.
- 脑脊液生物标志物显示IL-6和GFAP水平增加,趋势是衰老标志物减少和Aβ42.2增加.

Alzheimer's Disease: Treatment
212
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...

Alzheimer's Disease: Overview
517
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...
