Decision trees for predicting risk of multiple sclerosis

Published on August 15, 2023

Imagine if you could use a decision tree to predict the likelihood of developing multiple sclerosis (MS). That’s exactly what this study did! It used a unique machine learning algorithm to combine demographic risk factors like gender with important genetic markers to create a predictive tool. The researchers analyzed data from 619 healthy individuals and 299 MS patients, all from Sardinia. Surprisingly, they found that gender wasn’t a reliable factor in predicting MS, so they focused solely on genetic markers. With an impressive accuracy rate, their algorithm successfully identified 73.24% of MS patients and 66.07% of those without the disease. This opens up possibilities for clinicians to monitor individuals who have relatives with MS and help identify those at higher risk.

IntroductionMultiple sclerosis (MS) is a persistent neurological condition impacting the central nervous system (CNS). The precise cause of multiple sclerosis is still uncertain; however, it is thought to arise from a blend of genetic and environmental factors. MS diagnosis includes assessing medical history, conducting neurological exams, performing magnetic resonance imaging (MRI) scans, and analyzing cerebrospinal fluid. While there is currently no cure for MS, numerous treatments exist to address symptoms, decelerate disease progression, and enhance the quality of life for individuals with MS.MethodsThis paper introduces a novel machine learning (ML) algorithm utilizing decision trees to address a key objective: creating a predictive tool for assessing the likelihood of MS development. It achieves this by combining prevalent demographic risk factors, specifically gender, with crucial immunogenetic risk markers, such as the alleles responsible for human leukocyte antigen (HLA) class I molecules and the killer immunoglobulin-like receptors (KIR) genes responsible for natural killer lymphocyte receptors.ResultsThe study included 619 healthy controls and 299 patients affected by MS, all of whom originated from Sardinia. The gender feature has been disregarded due to its substantial bias in influencing the classification outcomes. By solely considering immunogenetic risk markers, the algorithm demonstrates an ability to accurately identify 73.24% of MS patients and 66.07% of individuals without the disease.DiscussionGiven its notable performance, this system has the potential to support clinicians in monitoring the relatives of MS patients and identifying individuals who are at an increased risk of developing the disease.
