- 生物标志物发现发现
- 神经学 神经学
背景情况:
- 肌缩侧面硬化症 (ALS) 是一种进展性神经退行性疾病.
- 目前对ALS的诊断方法缺乏明确的生物标志物,导致诊断延迟.
- 脑脊液 (CSF) 分析正在探索潜在的ALS生物标志物.
研究的目的:
- 在ALS患者中调查脑液中聚蛋白,蛋白,酸化蛋白和β-胺1-42的水平.
- 评估这些生物标志物在ALS的诊断潜力.

Alzheimer's Disease: Overview
491
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

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...

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.
