arXiv paper maps visual attribution of hand-drawn patterns to Parkinson's screening

A new arXiv preprint proposes an explainable screening approach for Parkinson's disease based on hand-drawn spirals and meanders. The work argues that tremor-driven oscillations, irregular strokes, and unstable curvature in these drawings reveal early neuromotor impairment. It then connects visual attribution methods to clinical reasoning so the model's outputs can be interpreted by clinicians.
