Working memory deficits in chronic fatigue syndrome: differentiating between speed and accuracy of information processing.
Deluca, John, Christodoulou, Christopher, Diamond, Bruce J et al.·Journal of the International Neuropsychological Society : JINS·2004
This study tested how quickly people with ME/CFS can process information (like reading or hearing something fast) and how well they can hold information in their working memory (like remembering a phone number while writing it down). The researchers found that people with ME/CFS without mental health conditions had slower information processing speeds, but their memory ability was normal. Interestingly, people with ME/CFS who also had depression or anxiety showed similar results to healthy people.
