Parkinson's disease patients have been found to demonstrate an improved working memory after a night's sleep; however, recent research suggests that sleep disorders can interfere with this benefit. The results of the study are published in Brain. Working memory, defined as the ability to temporarily store and manipulate information, can be affected during the course of Parkinson's disease, and this can result in deficits in planning, problem solving and independently completing daily tasks. Therefore, research suggests that addressing sleep disorders in these patients is of great importance; working memory capacity can potentially be improved with training.
