This isn’t specifically about CFS/ME or FMS, but I found it interesting, and I think it makes sense.
Why Mental Lethargy When Sick
During an infection, humans typically experience a set of physiological and psychological symptoms, including fever, confusion, decreased motivation, depression and anxiety that are accompanied by a slowing of movements.
These changes, collectively known as “sickness behavior,” are the body’s way of conserving energy during illness so that an effective immune response can be launched. This new study helps researchers further understand how cytokines communicate between the immune system and the brain to promote sickness behavior.
Since many people with CFS/ME have chronic fevers and other symptoms similar to those of infectious illnesses, I have to wonder if the results of this study will be examined with regard to CFS/ME.

Now, what would make interesting research is looking at the biological reasons we are in a chronic state of sickness behavior. :-)
