We know that sleep disorders have many consequences. Unfortunately it looks as though we might be able to add another one to the list: Parkinson’s disease.
A recent study found the incidence of Parkinson’s disease to be as high as 65% in those suffering from rapid eye movement sleep behavioral disorders. It was also found that as Parkinson’s disease progressed, the incidence of sleep disorders increased.
The authors then went on to identify a Japanese study that found men with excessive daytime sleepiness were three times more likely to develop Parkinson’s disease.
It’s worth noting that current data is limited, and that larger and better controlled studies are needed – hopefully we’ll see them in the not-too-distant future.
