This is the article ME/CFS patients need to print out and leave at some doctor's desks.
Excerpt:
The ME/CFS group showed no signs of muscle fatigue, and performed normally on cognitive tests, despite reporting greater cognitive symptoms.
And yet the immune and gut microbiome changes clearly impacted the central nervous system in several ways. People with ME/CFS had lower levels of chemicals called catechols, which help regulate the nervous system, in their cerebrospinal fluid and less activity in a brain region called the temporal-parietal junction (TPJ) during motor tasks.
The TPJ drives the motor cortex, a brain region in charge of telling the body to move, so its dysfunction might disrupt how the brain decides to exert effort, the researchers think. In turn, these changes might alter patients' tolerance for exertion and their perception of fatigue.
"We may have identified a physiological focal point for fatigue in this population," says Brian Walitt, lead author and medical scientist studying ME/CFS at NINDS.
"Rather than physical exhaustion or a lack of motivation, fatigue may arise from a mismatch between what someone thinks they can achieve and what their bodies perform."
