12/4/2025

Summary

Story summary

A study involving nearly 20,000 individuals by South Korean scientists found that untreated restless legs syndrome patients had a 2.1% incidence of Parkinson's disease.
Patients treated with a dopamine agonist had a 0.5% incidence, suggesting treatment lowers the risk.
The findings suggest restless legs syndrome may be an early marker for Parkinson's disease.
Sleep disruption and iron deficiency may contribute to the link, and early recognition could help patients.
