Story summary

A study conducted in South Korea finds that restless legs syndrome increases the risk of Parkinson's disease, with health records of 9,919 individuals showing 1.6% developing Parkinson's versus 1% in controls.
Dopamine agonists were linked to a lower risk, suggesting the link involves more than the dopaminergic pathway.
Researchers say RLS could be a risk factor rather than an early sign of Parkinson's and call for further study.
