Cardiac Rate and Cognition Linked

Researchers at the University of New South Wales studied 30 CFS patients and 40 healthy controls with EKG, perceived fatigue/effort and cognitive performance during mental tasks. They report: “Patients with CFS showed no deficits in performance accuracy, but were significantly slower than healthy controls. CFS was further characterized by low and unresponsive heart rate variability; greater heart rate reactivity and prolonged heart rate-recovery after cognitive challenge.” (PLoS ONE; Nov. 14, 2012)
