Cognitive dysfunction

Dr. John LaManca et al. administered IQ tests to ME/CFS patients and to a control group four hours and 24 hours after treadmill testing. The ME/CFS patients experienced a cognitive loss four hours after treadmill, which continued to persist for 24 hours. Usually when cognitive testing is repeated, learning occurs and there is a gain in score. The control group had a good improvement in score while the ME/CFS patients had scores that went down as they relapsed fol­lowing the treadmill testing.
