Imagine trying to navigate a vast and ever-changing landscape without a map. That’s the challenge researchers face when trying to predict the progression of Parkinson’s disease (PD). With its wide range of symptoms and lack of reliable markers, PD can be unpredictable. But now, a team of scientists has developed a new approach using the mapper algorithm, a powerful tool for analyzing complex data. By applying this method to data from the Parkinson’s Progression Markers Initiative, the researchers constructed a Markov chain that provides insight into how patients’ motor features evolve over time. This model not only allows for a quantitative comparison of disease progression under different medication regimens but also predicts patients’ scores on the UPDRS III assessment scale. Ultimately, this dynamic model has the potential to transform personalized treatment strategies for people with PD, helping clinicians tailor interventions to each individual and identify those who may be at risk for more severe symptoms.

BackgroundParkinson’s disease (PD) is a neurodegenerative disease with a broad spectrum of motor and non-motor symptoms. The great heterogeneity of clinical symptoms, biomarkers, and neuroimaging and lack of reliable progression markers present a significant challenge in predicting disease progression and prognoses.MethodsWe propose a new approach to disease progression analysis based on the mapper algorithm, a tool from topological data analysis. In this paper, we apply this method to the data from the Parkinson’s Progression Markers Initiative (PPMI). We then construct a Markov chain on the mapper output graphs.ResultsThe resulting progression model yields a quantitative comparison of patients’ disease progression under different usage of medications. We also obtain an algorithm to predict patients’ UPDRS III scores.ConclusionsBy using mapper algorithm and routinely gathered clinical assessments, we developed a new dynamic models to predict the following year’s motor progression in the early stage of PD. The use of this model can predict motor evaluations at the individual level, assisting clinicians to adjust intervention strategy for each patient and identifying at-risk patients for future disease-modifying therapy clinical trials.
