Description
Berginström and colleagues examine brain links tied to pain and fatigue in chronic pain patients. Their 2026 journal article uses resting state fMRI scans. Participants also performed a twenty-minute attention task designed to tire them.
The study included 24 women with chronic pain. It also included 22 healthy controls of similar age. Patients reported more fatigue and pain than controls. Before the task, the groups differed in several brain networks. The default mode network showed the clearest gaps. After the task, most group gaps could no longer be seen. Only links between the basal ganglia and frontal areas remained distinct. Pain-linked gaps showed up mainly before the task. Fatigue-linked gaps showed up after the task. The authors suggest fatigue can crowd out pain in brain activity.
