Classification of Illness

Classification of Illness

The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

概括

多发性硬化症 (MS) 通过机器学习被重新分类为疾病连续性,而不是不同的亚型. 这种基于残疾,脑损伤和活动的新模式,可以改善对数百万受MS影响的人的理解和治疗.

科学领域:

神经学神经学
数据科学数据科学数据科学
医学分类医学分类

背景情况:

传统的多发性硬化症 (MS) 亚型缺乏预后价值,并阻碍了药物发现.
目前的分类未能捕捉到MS的病理生物学和疾病的演变.
需要一种新的方法来更好地理解和管理MS.

研究的目的:

开发一个数据驱动的MS疾病演变的分类.
确定定义MS疾病状态的关键维度.
为改善患者管理和药物发现提出一个精细的分类.

主要方法:

对大型临床试验数据库的分析 (大约. 8000名患者) 使用概率机器学习.
包括临床数据,MRI扫描和患者访问.
在独立的临床试验数据库和真实世界队列 (超过4000名患者) 中验证.

主要成果:

确定了MS的四个维度:身体残疾,脑损伤,复发和亚临床疾病活动.
定义了疾病谱的两个极点:早期/轻度/进化 (EME) 的MS和高级的MS.
通过脑损伤积累,向晚期多发性硬化症转变,其进展独立于复发.

结论:

多发性硬化应该被视为一种疾病连续性,而不是单独的亚型.
拟议的分类提供了对MS的统一理解.
这种方法可以提高患者管理,加快MS的药物发现.
