“…That we did not find any evidence for between group differences suggests people with somatic hypervigilance are no slower (ART), no more impulsive (for example increased false positives), nor less accurate (for example overall errors) in identifying the stimulus in the presented paradigms than case-matched controls. A mismatch between neurophysiological and behavioural outcome measures as reported in this study, has been also been reported in the existing fibromyalgia literature (Glass, et al, 2011;Mercado, et al, 2013), albeit during tasks of inhibition. Here the task was thought to be too simple to tax the remaining cortical resources beyond their capacity to perform the task accurately and with speed.…”

“…This was also associated with a reduced activation of the caudate nucleus, lingual gyrus, temporal areas and the hippocampus in FM patients. Similarly, Mercado et al [ 62 ] found a significant emotional Stroop interference effect in FM patients when recording their brain activity with event-related potentials. The results of this study revealed that the cognitive inhibition associated with a very automatic response elicited greater prefrontal neural activity when symptom-related stimuli were processed.…”

The effect of depressive symptoms on cognition in patients with fibromyalgia

et al. 2018

BackgroundFibromyalgia (FM) patients frequently complain of cognitive problems, but it remains unclear whether these cognitive complaints can be attributed to a dysfunction of the central nervous system or if they can be explained by other factors associated with the disease, such as depression, anxiety and sleep dysfunction.MethodsOne hundred and ten patients with FM were compared with thirty-three patients diagnosed with a depressive disorder (DD) and fifty healthy controls (HC). Several measures of attention and executive functions were used to make these comparisons and the patients were also asked to complete questionnaires on depression, anxiety and sleep quality. Univariate analyses of covariance (ANCOVA) were performed to identify and control confounders and multiple linear models were used to examine the effects of fibromyalgia and depression on cognitive measures.ResultsFM and HC differed significantly with respect to depression, anxiety and sleep dysfunction, whereas FM and DD did not differ in terms of symptoms of depression and anxiety. However, FM was associated with a worse quality of sleep than DD. Comparisons of cognitive performance between groups showed that short-term and working memory and inattention measures were only associated with symptoms of depression, whereas selective attention was associated with both depression and fibromyalgia, and processing speed, cognitive flexibility and inhibitory control showed a significant interaction between depression and fibromyalgia. Moreover, cognitive flexibility and inhibition abilities were specifically associated with FM.ConclusionFM patients show a cluster of cognitive impairment in the attentional and executive domains, although some of the symptoms observed could be explained by the severity of the symptoms of depression, while others seem to depend on the effects of fibromyalgia. Implications of the findings for the understanding and management of cognitive impairment of FM patients are discussed.

“…Glass et al [63], who used neuroimaging, also identified altered brain activity in response to a motor inhibition task in the group of patients with fibromyalgia. The study by Mercado et al [64] followed similar lines, with the authors reporting that fibromyalgia patients experienced specific problems of cognitive inhibition when they were assessed using an emotional Stroop task and event-related potentials. Finally, Berryman et al [65], who carried out a systematic review and made a meta-analysis of executive function in people with chronic pain, also found evidence of minor to moderate impairment in response inhibition.…”

Patients with fibromyalgia showed executive dysfunction in subjective and objective measures, although most of this impairment was associated with mood disturbances. Exceptions to this general rule were observed in the impairment of working memory evidenced on the BRIEF-A scale and the inhibition impairment exhibited by the interference effect from the Stroop Test. The two types of measurement provide different yet complementary information.
