Abstract Background Fibromyalgia is a chronic pain disorder characterized by widespread musculoskeletal symptoms, primarily attributed to sensitization of somatosensory system carrying pain. Few reports have investigated the impact of fibromyalgia symptoms on cognition, corticomotor excitability, sleepiness, and the sleep quality — all of which can deteriorate the quality of life in fibromyalgia. However, the existing reports are underpowered and have conflicting directions of findings, limiting their generalizability. Therefore, the present study was designed to compare measures of cognition, corticomotor excitability, sleepiness, and sleep quality using standardized instruments in the recruited patients of fibromyalgia with pain-free controls. Methods Diagnosed cases of fibromyalgia were recruited from the Rheumatology department for the cross-sectional, case-control study. Cognition (Mini-Mental State Examination, Stroop color-word task), corticomotor excitability (Resting motor threshold, Motor evoked potential amplitude), daytime sleepiness (Epworth sleepiness scale), and sleep quality (Pittsburgh sleep quality index) were studied according to the standard procedure. Results Thirty-four patients of fibromyalgia and 30 pain-free controls were recruited for the study. Patients of fibromyalgia showed decreased cognitive scores (p = 0.05), lowered accuracy in Stroop color-word task (for color: 0.02, for word: 0.01), and prolonged reaction time (< 0.01, < 0.01). Excessive daytime sleepiness in patients were found (< 0.01) and worsened sleep quality (< 0.01) were found. Parameters of corticomotor excitability were comparable between patients of fibromyalgia and pain-free controls. Conclusions Patients of fibromyalgia made more errors, had significantly increased reaction time for cognitive tasks, marked daytime sleepiness, and impaired quality of sleep. Future treatment strategies may include cognitive deficits and sleep disturbances as an integral part of fibromyalgia management.

Course Changes

We studied cerebral hemodynamic response to a sequential motor task in 56 subjects to investigate the time course and distribution of blood oxygenation changes as monitored by near-infrared spectroscopy (NIRS). To address whether response is modulated by different performance velocities, a group of subjects (n = 12) was examined while performing the motor task at 1, 2, and 3 Hz. The results demonstrate that 1) the NIRS response reflects localized changes in cerebral hemodynamics, 2) the response, consisting of an increase in oxygenated hemoglobin concentration [oxy-Hb] and a decrease in deoxygenated hemoglobin concentration ([deoxy-Hb]), is lateralized and increases in amplitude with higher performance rates, and 3) changes in [oxy-Hb] and [deoxy-Hb] differ in time course. Changes in [oxy-Hb] are biphasic, with a fast initial increase and a pronounced poststimulus undershoot. The stimulus-associated decrease in [deoxy-Hb] is monophasic, and response latency is greater. We conclude that NIRS is able to detect even small changes in cerebral hemodynamic response to functional stimulation.

AbstractAdults identified as believers and sceptics based on self-reports from a supernatural beliefs scale were assessed on two measures of inhibition; the Stroop Color‐Word Task and the Wisconsin Card Sorting Test (WCST). Both groups were of equal educational status and background. However, believers made significantly more errors than sceptics on all subscales of the WCST but were equivalent in performance on the Stroop measure. This finding is consistent with the idea that supernatural beliefs in adults are related to some types of inhibitory control.

Moderate Stress

In two experiments, the authors investigated the influence of stress type (i.e., low/no stress, mental, and physical), level (i.e., low, moderate, and high), and Type × Level interaction on intuitive decision frequency, decision quality, and decision speed. Participants were exposed to mental (i.e., color word task, mental arithmetic) and/or physical stress (i.e., running) and then required to make decisions regarding videotaped offensive situations in basketball. Intuitive decision frequency, decision quality, and decision speed were measured for each trial. Study 1 used a between-subjects design whereby 20 participants were randomly assigned to each of the five stress conditions. Results revealed that moderate stress was associated with faster decisions. Study 2 replicated the design and aim of Study 1 using a within-subject methodology (n = 42). Results suggested that moderate stress levels produced better, faster decisions. In conclusion, moderate levels of stress were associated with the most desirable decision outcomes.
