Cognitive functioning in people with chronic fatigue syndrome: a comparison between subjective and objective measures.
Cockshell, Susan J, Mathias, Jane L·Neuropsychology·2014
This study looked at whether people with ME/CFS who report memory and concentration problems actually perform worse on cognitive tests. Fifty people with ME/CFS and 50 healthy controls completed questionnaires about their cognitive difficulties and took standardized memory and attention tests. Surprisingly, while people with ME/CFS reported significantly more cognitive problems in daily life, both groups performed similarly on the objective tests, and reported problems didn't match test results in either group.
