The study follows 1,280 patients for rapid-eye-movement (REM) sleep disorder.
The study is large as it includes around 1,280 patients. In fact, it is considered to be the largest study ever performed on patients with this disorder. Several institutions participated in the study spanning North America (the University of McGill), Europe and Asia.
Some of the benefits of this study can be:
1. Early identification of Parkinson’s disease.
2. Starting of early preventive therapy before the disease develops.
3. Focusing on underlying factors that can be common between REM sleep disturbances and Parkinson’s disease.
“We confirmed a very high risk of PD in people with REM sleep disorder and found several strong predictors of this progression,” says one of the researchers behind the study.
