概括
在阿尔茨海默病 (AD) 患者中,脊髓缩进展,与认知和功能能力恶化相关. 这项研究强调了脊髓变化与AD进展之间的未被研究的联系.
科学领域:
- 神经学 神经学
- 神经成像是一种神经成像.
- 老年学是一门学科.
背景情况:
- 阿尔茨海默病 (AD) 主要以大脑缩和记忆丧失而闻名.

主要方法:
- 使用了来自阿尔茨海默氏病神经成像计划 (ADNI) 数据库的连续磁共振成像 (MRI) 扫描.
- 在45名阿尔茨海默病患者和49名认知正常 (CN) 控制者身上测量了宫形态测量,超过1.5年.
- 使用回归分析将带缩率与认知衰退指标 (MMSE,CDR,FAQ) 相关联.
主要成果:
- 与对照人群相比,阿尔茨海默氏病患者的前后带宽度减小率显著增加 (-每月0.12%,p=0.036).
- 脊髓缩的较快发生率与迷你精神状态检查 (MMSE,r=0.320,p=0.037) 中得分的恶化有显著关联.

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...

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...

Cognitive Development During Adulthood
68
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

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.

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...

Neural Regulation
39.2K
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.
