Anxiety and sexual arousal have often been considered as incompatible. Since the end of the 20th Century, however, researches have impaired theories centred on the inhibitory effect of the stress and on peripheral explanations; they rather focus attention on the complexity of the relations between the two states and on cognitive mechanisms. <br />Now sexual arousal tends to be regarded as a complex response that requires the convergent interpretation of internal and external stimuli. Anxiety may have different effects on this process, sometimes neutral, sometimes facilitating and sometimes inhibitory. <br />On the one hand, anxiety can trigger a vegetative emotional reaction that may be associated to a concomitant erotic stimulation. Thus, anxiety facilitates the sexual response: this can be called a priming effect. This effect is regularly observed in labs, mainly among women. It likely also works in certain compulsive sexual behaviours or, more commonly, in those numerous persons that report being sexually aroused when stressed. <br />On the other hand, anxiety can cause a massive irruption of non erotic cues in working memory. Therefore, cognitive function available for treating erotic stimuli is diminished and sexual response is impaired. This is an effect of cognitive interference. A trait called erotophobia could be regarded as a vulnerability factor to cognitive interference. Erotophobic subjects are characterized by a trend to focus upon danger-related information when they are in a sexual situation and by a higher risk of sexual dysfunction. [less ▲]

We review the interest of cognitive event-related potentials (ERPs) in comatose, vegetative, or minimally conscious patients. Auditory cognitive ERPs are useful to investigate residual cognitive functions, such as echoic memory (MMN), acoustical and semantic discrimination (P300), and incongruent language detection (N400). While early ERPs (such as the absence of cortical responses on somatosensory-evoked potentials) predict bad outcome, cognitive ERPs (MMN and P300) are indicative of recovery of consciousness. In coma-survivors, cognitive potentials are more frequently obtained when using stimuli that are more ecologic or have an emotional content (such as the patient's own name) than when using classical sine tones.

"Oddball" paradigm studies of auditory P300 have yielded conflicting results in migraine. We therefore undertook an additional study of auditory event-related potentials (ERPs) using an improved method of EEG processing, strict criteria for patients selection, and comparison with behavioral data. Twenty-one healthy subjects were compared to 20 patients suffering from migraine without aura between attacks. Migraine patients differed significantly from control subjects on several parameters: shorter latency of N1 (Cz) evoked by standard stimuli, longer latencies of both P3a and P3b (Pz) evoked by target stimuli, longer interval between N1 and P3b (Cz), smaller P3b (Cz) amplitude, longer reaction time (RT), higher number of errors (false alarm and/or omissions) and higher mean score on Plutchik-Van Praag's (PVP) inventory for depression. Errors were significantly correlated with RT and PVP scores. From a behavioral perspective, these results may suggest that patients suffering from migraine without aura between attacks display a higher level of arousal and more superficial attention, but require more time for automatic and/or voluntary processes. According to the inverted U-shaped relationship between performance and arousal, these patients may have difficulties in adjusting their attention level to perform a task in a optimal way. [less ▲]

The day care centre appears to be a structure especially well suited for the management of mild to moderate Alzheimer patients. It constitutes a place in which performance in everyday life activities can be explored, and optimisation strategies can be installed before they are used at home. Another objective of the day care centre might also be to provide caregivers with support and ease the burden that the daily care of a demented patient represents. Finally, it may also help to alleviate the patient's loneliness. In this perspective, we describe the general organisation of the recently-created day care centre at the University Hospital of Liege. We also present the assessment and intervention programme which was conducted in this day care centre in order to reduce the generalised apathy and depressed mood observed in a 70-year-old Alzheimer patient (AM). This programme aimed at restoring a leisure activity (knitting) at home by proposing several adaptations designed to minimise the impact of AM's cognitive deficits on knitting activity. While an aggravation of her memory deficits was observed, the intervention significantly decreased AM's apathy and depressed mood as well as her husband's burden. [less ▲]

Nous proposons de réaliser une analyse du Rorschach d’un sujet schizophrène en phase de stabilisation. Le protocole ne répond pas aux critères de validité (moins de 14 réponses et refus de planche à 3 reprises) et ne permet donc pas de réaliser une analyse structurale complète selon les recommandations du Système Intégré. Cependant, une étude que nous qualifierons de « phénoménologique » se révèle intéressante. En centrant notre réflexion sur le processus de médiation cognitive, que le sujet emploie de manière idiosyncrasique lorsqu’il est confronté à la consigne du test, nous observerons que la démarche implicite de « fausse perception » qui est suggérée au sujet (« qu’est-ce que cela pourrait-être ? ») semble difficilement tolérable. La principale particularité de ce protocole consiste en une remise en question par le sujet des éléments perçus, pour finir, la plupart du temps, par rejeter la réponse fournie. Le recours à ce « doute méthodique » est superposable à ce que les théorisations modernes de la psychopathologie phénoménologique appellent l’« hyper-réflexivité schizophrénique » (Sass, 1992, 1994, 2001 ; Stanghellini, 2006). Nous pouvons également réaliser un rapprochement entre ce processus perceptif et les théories du « salience syndrome » développées par la neuropsychologie sociale (Van Os, 2009 ; Van Os & Kapur, 2009). Ces considérations nous permettent de rediscuter la pertinence de la remédiation cognitive basée sur la connaissance de la maladie et la reconnaissance des symptômes associés à laquelle a été soumis le patient. L’analyse du Rorschach nous donne également des informations intéressantes sur la stabilisation symptomatologique de notre patient et sur la composante résiduelle de son trouble schizophrénique. Ces observations semblent incompatibles avec des hypothèses homéostatiques et la possibilité d’un retour à un état antérieur à la schizophrénie, et démontrent l’utilité du diagnostic de schizophrénie résiduelle. Enfin, cette présentation cherchera à construire des ponts entre la méthode du Système Intégré et la psychopathologie phénoménologique moderne. [less ▲]

Nowadays, there is compelling evidence that there is a poor relationship between the incoming sensory input and the resulting pain sensation. Signals coming from the peripheral nervous system undergo a complex modulation by cognitive, affective, and motivational processes when they enter the central nervous system. Placebo- and hypnosis-induced analgesia form two extreme examples of how cognitive processes may influence the pain sensation. With the advent of modern brain imaging techniques, researchers have started to disentangle the brain mechanisms involved in these forms of cognitive modulation of pain. These studies have shown that the prefrontal and anterior cingulate cortices form important structures in a descending pathway that modulates incoming sensory input, likely via activation of the endogenous pain modulatory structures in the midbrain periaqueductal gray. Although little is known about the receptor systems involved in hypnosis-induced analgesia, studies of the placebo response suggest that the opiodergic and dopaminergic systems play an important role in the mediation of the placebo response.

Working memory problems have been identified as a core cognitive deficit in schizophrenia. In this paper, we present the results of a cognitive rehabilitation programme (Duval & Coyette, 2005) administered to a schizophrenia patient, and specifically designed to improve the updating sub-component of working memory. The original feature of this programme was that it involved two types of updating exercises: cognitive and ecological. The purpose was to enable the patient to acquire cognitive strategies that alleviate the mental load of the central executive and to transfer them to daily life. The specificity and efficacy of the programme were assessed with multiple (cognitive, ecological and non-target) baseline measurements. In addition, several questionnaires were administered to assess the effect of the programme on subjective cognitive complaints affecting daily life, psychiatric symptoms and self-esteem. The results demonstrated the efficacy of the rehabilitation programme on the updating function and the generalisation of these beneficial effects to daily life. A significant decrease in both subjective cognitive complaints and psychiatric symptoms was also observed. However, the patient's self-esteem did not improve. [less ▲]
