Multiple Sclerosis l: Introduction

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Background:

The BeCare MS Link mobile app collects patient-reported data for multiple sclerosis (MS) assessment.
It aims to digitally replicate established clinical metrics like the Expanded Disability Status Scale (EDSS).

Purpose of the Study:

To compare EDSS scores derived from the BeCare MS Link app with those from standard neurologist assessments.
To evaluate the accuracy of machine learning algorithms in predicting EDSS scores using app-derived data.

Main Methods:

35 MS patients' app-derived EDSS data were compared to neurologist-derived EDSS scores.
Four distinct machine learning algorithms (MLAs) predicted EDSS scores from app data.
Accuracy was assessed by comparing predicted scores to clinical scores.

Main Results:

The most accurate MLA achieved exact EDSS score matches in 19 cases and within 0.5 points in 21 cases.
Over 80% of all MLA-predicted scores were within 1 EDSS point of the clinical assessment.
Mean squared error ranged from 1.05 to 1.37 across the MLAs.

Conclusions:

The BeCare MS Link app effectively replicates the clinical EDSS assessment for MS patients.
This mobile application holds potential for a more thorough evaluation of disability in multiple sclerosis.
