Outcome: Not reported

Why it matters

These findings suggest that RLS may be linked to a variety of neurological disorders, which could influence further research into understanding these associations and their underlying mechanisms.

What this does not prove

The findings are based on observational studies, which can indicate associations but do not confirm causation. Additionally, the studies included are heterogeneous.

Next milestone

No next milestone was established from the available source.

findingsIn our exploratory synthesis of 119 unique studies, RLS was significantly associated with Parkinson's disease (case-control OR 3.22, 95% CI 2.35-4.41; cohort RR 1.74, 95% CI 1.02-2.95), multiple sclerosis (OR 4.04, 95% CI 3.26-5.00), neuromyelitis optica spectrum disorder (OR 2.91, 95% CI 1.45-5.84), migraine or headache disorders (forward OR 2.72, 95% CI 2.19-3.38; reverse adjusted OR 1.53, 95% CI 1.36-1.73), peripheral neuropathy (OR 3.82, 95% CI 2.49-5.83), epilepsy (OR 2.11, 95% CI 1.58-2.82), and amyotrophic lateral sclerosis (OR 7.69, 95% CI 2.74-21.59).

limitationsHowever, the current evidence remains observational and heterogeneous.
