Does predictability matter? Effects of cue predictability on neurocognitive mechanisms underlying prospective memory

2015

Prospective memory (PM) represents the ability to successfully realize intentions when the appropriate moment or cue occurs. In this study, we used event-related potentials (ERPs) to explore the impact of cue predictability on the cognitive and neural mechanisms supporting PM. Participants performed an ongoing task and, simultaneously, had to remember to execute a pre-specified action when they encountered the PM cues. The occurrence of the PM cues was predictable (being signalled by a warning cue) for some participants and was completely unpredictable for others. In the predictable cue condition, the behavioural and ERP correlates of strategic monitoring were observed mainly in the ongoing…

Anodal Transcranial Direct Current Stimulation Over Prefrontal Cortex Slows Sequence Learning in Older Adults

2022

Aging is associated with declines in sensorimotor function. Several studies have demonstrated that transcranial direct current stimulation (tDCS), a form of non-invasive brain stimulation, can be combined with training to mitigate age-related cognitive and motor declines. However, in some cases, the application of tDCS disrupts performance and learning. Here, we applied anodal tDCS either over the left prefrontal cortex (PFC), right PFC, supplementary motor complex (SMC), the left M1, or in a sham condition while older adults (n = 63) practiced a Discrete Sequence Production (DSP), an explicit motor sequence, task across 3 days. We hypothesized that stimulation to either the right or left P…

Validating Habitual and Goal-Directed Decision-Making Performance Online in Healthy Older Adults

2021

Everyday decision-making is supported by a dual-system of control comprised of parallel goal-directed and habitual systems. Over the past decade, the two-stage Markov decision task has become popularized for its ability to dissociate between goal-directed and habitual decision-making. While a handful of studies have implemented decision-making tasks online, only one study has validated the task by comparing in-person and web-based performance on the two-stage task in children and young adults. To date, no study has validated the dissociation of goal-directed and habitual behaviors in older adults online. Here, we implemented and validated a web-based version of the two-stage Markov task usi…

Clinical Onset and Multiple Sclerosis Relapse after SARS-CoV-2 Infection

2021

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been associated with several neurological disorders including headache, facial palsy, encephalitis, stroke, demyelinating disorders. The present report will discuss cases of multiple sclerosis (MS) onset and relapse both beginning early after SARS-CoV-2 infection. In both cases, magnetic resonance imaging (MRI) showed widespread bilateral subcortical and periventricular active lesions. Serum IgG against SARS-CoV-2 Spike antigens confirmed seroconversion with titers that are considered not definitely protective against possible reinfection. We hypothesize that SARS-CoV-2 infection, as previously reported for other vir…

SOIGNER AUX FRONTIÈRES : REGARD PSYCHODYNAMIQUE SUR LE QUOTIDIEN TRAUMATIQUE DES SOIGNANTS/RÉFUGIÉS

2017

Les soignants d’hôpitaux habitant et travaillant aux frontières turco-syriennes sont aussi des migrants ou des réfugiés syriens. Comme la population sinistrée, ils exercent leur activité professionnelle au rythme de la guerre et nécessitent également un accompagnement. Dans le cadre de l’Unité psychosociale d’une ONG internationale, un soutien psychologique en visio-conférence est proposé aux soignants en Syrie et en Turquie. Cet article propose un commentaire et une réflexion clinique sur le quotidien de ces soignants, leur santé mentale, ainsi que sur leurs mécanismes de survie psychiques, groupaux et culturels. Quatre vignettes cliniques sont commentées et discutées pour comprendre la co…

The Unseen, the Discouraged, and the Outcast : Expressivity and the Foundations of Social Recognition

2018

AbstractThis article analyzes different pathologies of social affirmation and examines the grounds of social recognition from the point of view of the concept of expression. The red thread of the text is provided by Tove Jansson’s fictional works, and the focus will be on three cases in particular (the magic hat, the invisible girl and the figure of the Groke). The article sets out from the phenomenological distinction between the sensible expression, on the one hand, and the expressed content, on the other. By focusing on the three cases, the article distinguishes and analyses the fundamental structures of communal life and explicates different ways in which social affirmation can be one-s…

Retinal Vascular Assessment in Psoriasis: A Multicenter Study

2021

PurposeTo investigate the vascular status of the macula in psoriasis patients without history of ocular inflammation by Optical Coherence Tomography Angiography (OCTA).MethodsThis prospective cross-sectional multicenter study included 55 psoriasis patients and 55 control healthy subjects. A complete eye examination and 6 mm × 6 mm OCTA imaging were performed. Retinal vascular status was evaluated by analyzing vascular density (VD) of superficial vascular plexus (superficial wVD) and deep vascular plexuses (deep wVD) in a 6 mm × 6 mm area and in foveal (superficial fVD and deep fVD) and parafoveal sectors (superficial pVD and deep pVD). In addition, foveal thickness (FT) and foveal avascular…

Online interventions to prevent mental health problems implemented in school settings: the perspectives from key stakeholders in Austria and Spain

2021

Abstract Background Schools are key settings for delivering mental illness prevention in adolescents. Data on stakeholders’ attitudes and factors relevant for the implementation of Internet-based prevention programmes are scarce. Methods Stakeholders in the school setting from Austria and Spain were consulted. Potential facilitators (e.g. teachers and school psychologists) completed an online questionnaire (N=50), policy makers (e.g. representatives of the ministry of education and health professional associations) participated in semi-structured interviews (N=9) and pupils (N=29, 14–19 years) participated in focus groups. Thematic analysis was used to identify experiences with, attitudes a…

Systematic review and exploratory meta-analysis of the efficacy, safety, and biological effects of psychostimulants and atomoxetine in patients with …

2019

ObjectiveOur aim was to summarize the efficacy and safety of atomoxetine, amphetamines, and methylphenidate in schizophrenia.MethodsWe undertook a systematic review, searching PubMed/Scopus/Clinicaltrials.gov for double-blind, randomized, placebo-controlled studies of psychostimulants or atomoxetine in schizophrenia published up to 1 January 2017. A meta-analysis of outcomes reported in two or more studies is presented.ResultsWe included 22 studies investigating therapeutic effects of stimulants (k=14) or measuring symptomatic worsening/relapse prediction after stimulant challenge (k=6). Six studies of these two groups plus one additional study investigated biological effects of psychostimu…
