Here’s a rare early preventative measure for diagnosing Parkinson’s. In a study of restless sleep, researchers found that older patients who are suddenly “acting out” their dreams are at a much greater risk of developing Parkinson’s later on. The acting out is called REM sleep behavior disorder, and shows a high correlation with Lewy bodies in the brain. The symptoms of restless sleep showed up an average of six years before any other symptoms of Parkinson’s.
You can find the abstract here. The correlation was very high. Of 175 patients, the majority had issues. But most of the patients were men, so the study may not apply to women.
