Migraine has been considered a chronic neuronal-based pain disorder characterized by the presence of cortical hyperexcitability. The Contingent Negative Variation (CNV) is the most explored electrophysiological index in migraine. However, the findings show inconsistencies regarding its functional significance. To address this, we conducted a review...

A large number of publications have focused on the study of pain expressions. Despite the growing knowledge, the availability of pain-related face databases is still very scarce compared with other emotional facial expressions. The Pain E-Motion Faces Database (PEMF) is a new open-access database currently consisting of 272 micro-clips of 68 differ...

Fibromyalgia is a chronic pain syndrome characterized by dysfunctional processing of nociceptive stimulation. Neuroimaging studies have pointed out that pain-related network functioning seems to be altered in these patients. It is thought that this clinical symptomatology may be maintained or even strengthened because of an enhanced expectancy for...

Recent findings have associated different COMT genotypes with working memory capacity in patients with fibromyalgia. Although it is thought that the COMT gene may influence neural correlates (P2 and P3 ERP components) underlying working memory impairment in this chronic-pain syndrome, it has not yet been explored. Therefore, the aim of the present...

Recent findings have associated different COMT genotypes with working memory capacity in patients with fibromyalgia. Although it is thought that the COMT gene may influence neural correlates (P2 and P3 ERP components) underlying this cognitive dysfunction it has not been still explored. 51 patients and 51 healthy control participants took part in t...

Growing evidence indicates that cognitive slowness in fibromyalgia patients constitutes one of the main concerns. This slowing, together with the physical and affective symptomatology that characterises them, significantly affects their quality of life. The main objective of the present study was to design and apply a cognitive training program to...

Background One of the major cognitive deficits in fibromyalgia has been linked to the hypervigilance phenomenon. It is mainly reflected as a negative bias for allocating attentional resources towards both threatening and pain-related information. Although the interest in its study has recently grown, the neural temporal dynamics of the attentional...

Objective Cognitive dysfunction in fibromyalgia has become a key symptom considered by patients as more disabling than pain itself. Experimental evidence from neuropsychological and neuroimaging studies indicates that such cognitive impairments are especially robust when patients need to set in motion working memory processes, suggesting the existe...

Previous research has shown a consistent association among genetic factors, psychological symptoms and pain associated with fibromyalgia. However, how these symptoms interact to moderate genetic factors in fibromyalgia has rarely been studied to date. The present research investigates whether psychological symptoms can moderate the effects of catec...

Growing research has reported the presence of a clear impairment of working memory functioning in fibromyalgia. Although different genetic factors involving dopamine availability (i.e, the COMT gene) have been associated with the more severe presentation of key symptoms in fibromyalgia, scientific evidence regarding the influence of COMT genotypes...

Pain experience involves a complex relationship between sensory and both emotional and cognitive factors, which appear to be mediated by different neural pathways. Previous evidence has shown that whereas conscious processing of unpleasant stimuli enhances pain perception, the influence of emotions on pain under unaware conditions is much less know...

Participants A total of fifty-six right-handed women (29 healthy control (HC) subjects and 27 FM patients) took part in the experiment. All participants were aged between 33 and 63 years. Patients fulfilled the 1990 American College of Rheumatology (ACR) diagnostic criteria for FM. The sample of HC participants was made up in such a way as to allow...

Pain perception arises from a complex interaction between a nociceptive stimulus and different emotional and cognitive factors, which appear to be mediated by both automatic and controlled systems. Previous evidence has shown that whereas conscious processing of unpleasant stimuli enhances pain perception, emotional influences on pain under unaware...

Background Distinct experimental studies have been conducted in persons with chronic pain in order to explore possible attentional bias towards pain related stimuli. One of the most applied experimental paradigms, in this context, is the emotional stroop task in which words with different emotional content are presented to the subjects (Andersson &...

Background Fibromyalgia (FM) is a chronic condition characterized by the presence of pain, fatigue and cognitive dysfunction, among other symptoms. Previous research (Duschek et al., 2014) also indicated that patients show an hypervigilance pattern to pain and negative information that interferes with the processing of other events by capturing att...

Background Fibromyalgia constitutes a chronic pain syndrome that has been also characterized by an altered cortical processing of emotional stimulation (Montoya et al., 2005). Furthermore, several studies have indicated that such dysfunction in the emotional processing could be related to the presence of attentional biases towards threat-related in...

Exogenous or automatic attention to emotional distractors has been observed for emotional scenes and faces. In the language domain, however, automatic attention capture by emotional words has been scarcely investigated. In the current event-related potentials study we explored distractor effects elicited by positive, negative and neutral words in a...

Objective The primary symptom of fibromyalgia is chronic, widespread pain; however, patients report additional symptoms including decreased concentration and memory. Performance-based deficits are seen mainly in tests of working memory and executive functioning. It has been hypothesized that pain interferes with cognitive performance; however, the...

Unlabelled: The primary symptom of fibromyalgia (FM) is chronic, widespread pain; however, patients report additional symptoms including decreased concentration and memory. Performance-based deficits are seen mainly in tests of working memory and executive function. Neural correlates of executive function were investigated in 18 FM patients and 14...

In recent years, a good deal of serious research has been carried out on the hypothesized presence of generalized hypervigilance to sensory stimulation in fibromyalgia (FM). However, there are no studies which, following an operationalization of generalized hypervigilance as a propensity to attend to any task-irrelevant stimuli presented, make use...

This study set to explore whether variables related to cognitive-affective assets would complement measures of psychological vulnerability for the prediction of physical functioning and pain tolerance in 138 women with Fibromyalgia Syndrome (FMS). Depression, anxiety, stress response and negative affect were defined a priori as measures of vulnerab...

p>El Aprendizaje basado en Problemas (ABP) se ha presentado, desde sus inicios, como una propuesta educativa innovadora, que se caracteriza porque el aprendizaje está centrado en el estudiante, promoviendo que éste sea significativo, además de desarrollar una serie de habilidades y competencias indispensables en el entorno profesional. Además, en e...

This study evaluates a structural equation model (SEM) of linkages among cognitive control resources (illness-specific efficacy beliefs and internal pain control expectancies), stress/recovery state, and affective discomfort in women with fibromyalgia (n=130). Results were consistent with the proposal that stress/recovery balance mediates the relat...

Evidence coming from neuropsychological studies has showed the presence of cognitive alterations in fibro-myalgia. Such dysfunctions are especially remarkable when the set in motion of executive control processes, such as inhibition, is required to perform successfully; however, neural data related to these mechanisms are very scarce. Present study...

El presente estudio evalúa un modelo estructural de relaciones entre los recursos cognitivos de control percibido sobre la enfermedad (expectativas de autoeficacia y lugar de control interno de dolor), el estado de estrés-recuperación y el malestar afectivo en mujeres con fibromialgia (n= 130). Los resultados fueron consistentes con la propuesta de...
