Objective:

To critically appraise current symptom-based classification systems of non-motor symptoms (NMS) in Parkinson's disease (PD) and explore emerging models that may better capture their complexity.

  • Remove claims about quality of life and under-recognition unless directly supported by the source.
  • Ensure all findings are directly sourced from the narrative review.
Interpretation:

Remove unsupported conclusions about classification frameworks.

Limitations:
  • Ensure limitations are directly sourced from the narrative review.
Conclusion:

Remove or rephrase to avoid unsupported claims about the necessity for a new classification system.
