Abstract

The tools of mathematical modelling offer promising possibilities in our attempts to deepen our knowledge of insufficiently well-understood diseases such as multiple sclerosis. In this article we formulate a mathematical model, mainly based on differential equations, while gradually incorporating the needed modifications to the model with the aim of more accurately simulating the typical qualitative behaviours of the different types of MS. The agents active in the disease process are grouped in two main categories—beneficial cells and harmful cells, based on their influence on the nervous system. In this text a deterministic as well as a stochastic model are proposed, with the goal of the stochastic model being a better representation of the observed irregularities in the occurrence of relapses and remissions in MS. The dynamics of the cell types’ concentrations are modelled through the utilization of appropriate periodic functions. The analytical properties of the models are studied and the connection between parameter values, initial conditions and end results is utilized to produce models capable of simulating disease courses with quantitative characteristics in accordance with real-world clinical data.

多发性硬化症患者残疾进展的数学模型
数学建模的工具为我们加深对诸如多发性硬化症等尚未充分了解的疾病的认识提供了有希望的可能性。在本文中,我们建立了一个主要基于微分方程的数学模型,同时逐渐对模型进行必要的修改,目的是更准确地模拟不同类型ms的典型定性行为。在疾病过程中活跃的因子根据其对神经系统的影响分为两大类-有益细胞和有害细胞。本文提出了一个确定性和随机模型,目标是随机模型能更好地表示ms中复发和缓解发生的观察到的不规则性。细胞类型浓度的动力学通过利用适当的周期函数来建模。研究了模型的解析性质,并利用参数值、初始条件和最终结果之间的联系,生成了能够根据实际临床数据模拟具有定量特征的疾病过程的模型。

期刊介绍: Acta Biotheoretica is devoted to the promotion of theoretical biology, encompassing mathematical biology and the philosophy of biology, paying special attention to the methodology of formation of biological theory. Papers on all kind of biological theories are welcome. Interesting subjects include philosophy of biology, biomathematics, computational biology, genetics, ecology and morphology. The process of theory formation can be presented in verbal or mathematical form. Moreover, purely methodological papers can be devoted to the historical origins of the philosophy underlying biological theories and concepts. Papers should contain clear statements of biological assumptions, and where applicable, a justification of their translation into mathematical form and a detailed discussion of the mathematical treatment. The connection to empirical data should be clarified. Acta Biotheoretica also welcomes critical book reviews, short comments on previous papers and short notes directing attention to interesting new theoretical ideas.
