概括
生物学定义正在将重点从临床症状转移到像阿尔茨海默氏症和帕金森症这样的神经退行性疾病的潜在机制. 本摘要讨论了在多发性硬化症中对生物定义的潜在转变,强调了当前的挑战和道德考虑.
科学领域:
- 神经免疫学 神经免疫学
- 神经学 神经学
- 生物标志物发现发现
背景情况:
- 最近的进展为阿尔茨海默病 (AD) 和帕金森病 (PD) 提出了生物学定义,超出了痴呆症或帕金森症等临床描述者的范围.
- 多发性硬化症 (MS) 也准备迎来类似的转向生物定义的转变.
- 与AD和PD不同,MS缺乏单一的,统一的分子驱动因子 (例如,AD中的粉样蛋白) 作为其致病因子,历史候选者包括T细胞,大脑缩和"燃烧疾病".
研究的目的:
- 探索开发多发性硬化症生物学定义的含义和挑战.
- 为了解决MS病变发生的确定的最低标准的缺乏.
- 积极考虑与MS生物评估相关的伦理问题和技术限制.

Parkinson's Disease: Overview
482
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

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.

Alzheimer's Disease: Overview
448
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...

Disorders of the Nervous Tissue

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
