Data-driven disease progression models of Alzheimer’s disease are important for clinical prediction model development, disease mechanism understanding and clinical trial design. Among them, dynamical models are particularly appealing because they are intrinsically interpretable. Most dynamical models proposed so far are consistent with a linear chain of events, inspired by the amyloid cascade hypothesis. However, it is now widely acknowledged that disease progression is not fully compatible with this conceptual model, at least in sporadic Alzheimer’s disease, and more flexibility is needed to model the full spectrum of the disease. We propose a Bayesian model of the joint evolution of brain image-derived biomarkers based on explicitly modelling biomarkers’ velocities as a function of their current value and other subject characteristics. The model includes a system of ordinary differential equations to describe the biomarkers’ dynamics and sets a Gaussian process prior to the velocity field. We illustrate the model on amyloid PET SUVR and MRI-derived volumetric features from the ADNI study.
