Dynamical systems modeling reveals that ageing reserve governs physiological collapse in Parkinson disease multimorbidity, suggesting archetype-specific therapy selection.

Key Points

To determine how systemic ageing reserve and multiorgan vulnerability dictate physiological collapse and differential drug responses in Parkinson disease multimorbidity.
Constructed a three-layer textual-numeric-graph model (80 entities, 141 signed relations) coupled with an eight-state dynamical field capturing body-first and brain-first priming mechanisms.
Simulated 52,000 virtual patient trajectories to define five multimorbidity archetypes and applied sparse symbolic regression to discover governing state equations.
Assessed drug interventions (lixisenatide, ambroxol, and ursodeoxycholic acid) across archetypes using mechanism-feasibility Pareto frontier analysis.
The dominant system eigenvalue crossed zero at a dimensionless reserve threshold of R* = 0.72, and a learned physiological-complexity threshold classified simulated collapse with an AUROC of 0.95.
Sparse symbolic regression accurately reconstructed all eight state equations, achieving R² values between 0.94 and 1.00.
Lixisenatide, ambroxol, and ursodeoxycholic acid formed a mechanism-feasibility Pareto frontier, but optimal therapeutic perturbation strategies differed significantly across distinct multimorbidity archetypes.
