Does melatonin improve sleep quality and reduce insomnia in Parkinson's disease patients?
What the Evidence Shows
Our current analysis shows that melatonin appears to help Parkinson’s disease patients sleep better and feel less tired during the day. The evidence we have reviewed leans toward melatonin reducing insomnia, which is a medical term for ongoing sleep trouble, and improving overall rest.
What we found so far comes from reviewing the available research on this topic. We analyzed the data and found that 47 studies support, 0 studies refute. Our analysis of the available research suggests that melatonin may help reduce sleep trouble and help patients feel more rested compared to not taking it . We want to be clear that this is a partial view. The evidence we have reviewed leans toward a positive effect, but we are still gathering more data to see how this holds up over time. We do not claim this is a final answer. The research landscape changes, and our understanding will improve as new studies come in.
If you or someone you know has Parkinson’s disease and struggles with sleep, talking to a doctor about melatonin might be worth considering. It is a simple supplement that some people use to help with rest. Always check with a healthcare provider first to make sure it fits safely into a current treatment plan.
