Editing Working memory (section)

===Parkinson's disease===
Patients with [[Parkinson's]] show signs of a reduced verbal function of working memory. They wanted to find if the reduction is due to a lack of ability to focus on relevant tasks, or a low amount of memory capacity. Twenty-one patients with Parkinson's were tested in comparison to the control group of 28 participants of the same age. The researchers found that both hypotheses were the reason working memory function is reduced which did not fully agree with their hypothesis that it is either one or the other.<ref>{{cite journal | vauthors = Lee EY, Cowan N, Vogel EK, Rolan T, Valle-Inclán F, Hackley SA | title = Visual working memory deficits in patients with Parkinson's disease are due to both reduced storage capacity and impaired ability to filter out irrelevant information | journal = Brain | volume = 133 | issue = 9 | pages = 2677–2689 | date = September 2010 | pmid = 20688815 | pmc = 2929336 | doi = 10.1093/brain/awq197 }}</ref>
