Development of a Machine Learning System for Predicting Disease Progression Using Biomarker Data

The client faces challenges in reliably predicting the progression of neurodegenerative diseases like Parkinson’s, due to incomplete biomarker data and lack of personalized predictive tools. Current methods rely on subjective assessments and are insufficient to forecast individual disease trajectories, limiting the effectiveness of early interventions and tailored treatments.

A mid-sized healthcare research organization focused on neurodegenerative disorders, aiming to improve early diagnosis and personalized treatment strategies.
