概括

患有失眠的阿尔茨海默氏症患者可能有肠道细菌,如与睡眠质量相关的Bifidobacterium. thalamic代谢可能会调解这种联系,这表明益生菌和代谢治疗可以帮助改善睡眠.

科学领域:

神经科学是一个神经科学.
微生物学微生物学
睡眠医学睡眠医学

背景情况:

以前的研究探讨了阿尔茨海默病 (AD) 病理和肠道微生物群,AD和睡眠,以及睡眠和肠道微生物群之间的联系.
没有先前的研究研究了AD患者中这三个因素之间的相互关联关系.

研究的目的:

探索大脑病理,肠道微生物群和阿尔茨海默病患者的睡眠质量之间的关系.
通过整合这三个因素,为阿兹海默症患者的失眠治疗提供参考.

主要方法:

65名AD患者被分为ID (n=30) 和非ID (n=35) 组.
使用匹兹堡睡眠质量指数 (PSQI) 评估睡眠质量.
使用18F-氧葡萄糖 (FDG) -PET扫描来评估大脑新陈代谢,并通过16SrRNA测序分析肠道微生物群组成.

主要成果:

在PSQI得分,乳头糖代谢 (FDG-PET) 和特定肠道细菌 (Roseburia, Prevotella 7, Bifidobacterium) 的丰富性方面,观察到群体之间的显著差异.
两组之间没有发现粉样β沉积 (AV45-PET) 的显著差异.
在ID组中,PSQI得分与体FDG吸收和Bifidobacterium丰富度有负相关性.

结论:

甲状腺葡萄糖代谢部分调解了Bifidobacterium和AD患者的睡眠质量之间的关联.
这表明,针对肠道微生物群 (例如益生菌) 和增强大脑新陈代谢的干预措施可能会改善这一群体的睡眠质量.

关键词:

Alzheimer's Disease: Overview

Alzheimer's Disease: Overview

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...

Insomnia

Insomnia

Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.
Multiple factors contribute...
