    Parkinson's disease (PD) lacks reliable non-invasive diagnostic biomarkers, making early diagnosis a significant clinical challenge.

  • 2

    This pilot study utilized a matched-pair cohort of PD patients and their healthy spouses to control for environmental confounders.

  • 3

    Untargeted LC–MS metabolomics identified a preliminary five-metabolite panel with promising discriminative performance (AUC > 0.95).

  • 4

    The study's primary contribution is demonstrating a controlled design to isolate PD-specific metabolic signatures for future validation.

  • 5

    Results are exploratory and not intended as a validated diagnostic tool, highlighting the need for larger independent cohort studies.
