A small study seems to indicate that RLS is triggered in genetically predisposed people by Viruses & infectious agents.
Obviously it's a small study and further detailed research will be needed to confirm the preliminary findings.
I found it interesting because MS is caused/triggered by Epstein Barr Virus.
30% of MS also have RLS. So clearly genetic predisposition PLUS the virus are needed to trigger RLS.
MS research is looking at anti viral therapy. Perhaps that research will also help RLS patients.
Viruses are notorious for triggering neurological disease.
Yet again- more funding and more research are essential for RLS.
