概括
肉,或肌肉损失,与阿尔茨海默病 (AD) 的进展和较差的临床结果有关. 管理肉可能有助于预防或减缓阿尔茨海默病及其相关认知能力下降的发展.
科学领域:
- 神经科学是一个神经科学.
- 老年学是指老年学的学科.
- 衰老的生物标志物
背景情况:
- 低体重指数是阿尔茨海默病 (AD) 和粉样蛋白β (Aβ) 沉积的已知危险因素.
- 萨尔科佩尼亚 (与年龄相关的肌肉质量和力量的损失) 和Aβ确认的AD之间的关系尚不清楚.
研究的目的:
- 为了调查萨尔科佩尼亚和阿尔茨海默氏病连续体之间的关联.
- 探索阿尔茨海默氏病连续体内萨尔科佩尼亚对临床结果的影响.
主要方法:

- 使用双能量X射线吸收度和手握强度评估萨科佩尼亚.
- 用Aβ正子发射断层扫描定义的AD连续;通过海马体积,MMSE,SVLT和CDR-SOB得分来评估临床严重程度.
主要成果:
- 麻症与AD连续性 (OR=4.99,p=0.004) 独立相关,即使在对混因素进行控制后也是如此.
- 在患有AD连续性的参与者中,皮症与海马体积下降相关 (β=-0.206,p=0.020).
- 肉症与较差的临床结果有关,包括较低的MMSE (β=-1.364,p=0.025),较低的SVLT得分 (β=-1.077,p=0.025) 和较高的CDR-SOB得分 (β=0.783,p=0.022).
结论:
- 萨科佩尼亚与阿尔茨海默病连续性有关,并预测临床结果更差.

Alzheimer's Disease: Overview
452
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...

Parkinson's Disease: Overview
498
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Dementia
107
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.
The progression of dementia is generally gradual....

Alzheimer's Disease: Treatment
170
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...

Neural Regulation

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.
