Author’s definition

This is the clouded thinking that is found in many fibromyalgia patients. In the author’s clinical experience it is strongly related to poor sleep. It manifests in a number of cognitive domains. Fibromyalgia patients have shown e deficits in tests of attention, executive functioning and verbal memory. (Cognitive functioning in fibromyalgia: The central role of effort.

Impaired performance

A study was done by Bar-On Kalfon et al. of “effort in the cognitive impairment in fibromyalgia patients” which looked at it “alongside common symptoms of pain, fatigue and depression”. These patients had an assessment that included “memory, executive function, attention and information processing speed”. Their effort was assessed using the Test of Memory Malingering (TOMM). “According to the TOMM, sub-optimal effort was shown by 16% of patients. TOMM scores were not associated with pain, fatigue or depression.”

Generally, results also “showed impaired performance on the memory, attention and information processing speed domains.” The authors concluded that their “findings confirm impaired attention and processing speed in fibromyalgia patients, independent of effort level. Nonetheless, the findings point to a general and strong effect of effort on neuropsychological performance in fibromyalgia patients, especially in the domain of memory, emphasizes the importance of effort testing in this population.” (Cognitive functioning in fibromyalgia: The central role of effort.
