Machine Learning Detects Pattern of Differences in Functional Magnetic Resonance Imaging (fMRI) Data between Chronic Fatigue Syndrome (CFS) and Gulf War Illness (GWI).

Provenzano, Destie, Washington, Stuart D, Rao, Yuan J et al.·Brain sciences·2020

This study used brain imaging (fMRI) and computer learning programs to see if people with ME/CFS and Gulf War Illness have different patterns of brain activity during memory tasks, both before and after exercise. Researchers found that computer programs could correctly distinguish between the two conditions about 75-82% of the time, and identified about 30-33 brain regions that showed different activation patterns between the two groups. This suggests that ME/CFS and Gulf War Illness may have measurable biological differences in how the brain works during cognitive tasks and recovery from exertion.

Cognitive Function Declines Following Orthostatic Stress in Adults With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS).

van Campen, C Linda M C, Rowe, Peter C, Verheugt, Freek W A et al.·Frontiers in neuroscience·2020

This study found that people with ME/CFS experience significant problems with memory and thinking speed after their body has been stressed by a tilt test (a medical test that checks how the body handles position changes). Specifically, when tested right after the tilt procedure, patients made more mistakes on memory tasks and responded much more slowly compared to before the test. This suggests that the physical stress of orthostatic intolerance directly worsens cognitive problems in ME/CFS.
