Korean researchers suggest they have found a link between restless leg syndrome (RLS) and an increased risk of developing Parkinson's disease. RLS is a neurological condition causing an irresistible urge to move your legs, and the team say from nearly 10,000 patients with the condition that they studied, there was a statistically significantly higher risk of developing Parkinson's, in comparison to people without RLS. Additionally, the team found patients with RLS that were treated with drugs that mimic dopamine in the brain had a longer length of time before they developed Parkinson's than those who were not given the meds.
