Why do we feel listless when we are recovering from an illness? The answer is, apparently, that low-grade chronic inflammation interferes with the dopaminergic signaling system in the brain that motivates us to do things.

This was reported in a new paper published in the journal Trends in Cognitive Sciences.

The research carried out at Emory University explains the links between the reduced release of dopamine in the brain, the motivation to do things, and the presence of an inflammatory reaction in the body. It also presents the possibility that this is part of the body’s effort to optimize its energy expenditure during such inflammatory episodes, citing evidence gathered during their study.

The authors also published an experimental framework based on computational tools, devised to test the theory.
