A New Machine Learning Approach to Predict Disease Course in Multiple Sclerosis
Objectives: This work aims at using Patient Reported Outcomes (PROs), Clinical Scales (CS) and anthropometric measures, collected within the Italian MS Foundation (FISM) initiative PROMPRO-MS dataset, for the detection of MS courses by means of machine learning (ML) techniques.
Methods: The set of PRO and CS was: EDSS; FIM; Edinburgh Handedness Inventory; Abilhand; MoCA; PASAT 3; SDMT; HADS; LSI; OAB-q; MFIS for a total of 126 features. 852 people with MS (PwMS), followed by Italian MS Society Rehabilitation Centre (Genoa, Padova, Vicenza), have been enrolled in the study. Data are acquired longitudinally every 3-4 months from January 2014. The proposed ML analysis is conducted on a dataset presenting the first time point of the 852 subjects and the 126 features.
Results: The applied ML techniques showed that PwMS diagnosed as relapsing-remitting (RR) could be isolated from other clinical courses (ALL). In particular, nine “top” questions were selected by the ‘Features Selection’ supervised (FS) algorithm: one question from LSI, three items from FIM; one from MFIS, one from HADS, one from MoCA, one from SDMT and one from Abilhand.
Conclusions: To the very best of our knowledge this is the first study which predicted MS course taking only into account a small subset of anthropometric and questionnaires variables, which could be proposed as a novel questionnaire, tailored for RR detection.
