Sleep linked to improved memory in Parkinson's disease patients

Sleep linked to improved memory in Parkinson's disease patients
23rd August 2012

The memory of Parkinson's disease patients could be improved by sleep, according to a recent study.

Researchers found that people with the condition perform better on tests for working memory after a night's sleep. However, sleeping disorder can prevent patients from feeling this benefit.

It is claimed that the discovery stresses the importance of addressing sleep disorders as part of Parkinson's disease care and indicate that working memory could be improved with training.

Dr Michael Scullin, first author of the paper, commented: "It was known already that sleep is beneficial for memory, but here, we've been able to analyze what aspects of sleep are required for the improvements in working memory performance."

However, the reasons behind the ability of sleep to temporarily improve memory are still unknown.

With rest also proven to also enhance motor function, more research is needed to create a better understanding of the phenomenon and develop possible new therapies.
