Cortical beta power reflects the influence of Pavlovian cues on human decision-making.

Reward-predictive cues can affect decision-making by enhancing instrumental responses towards the same (Specific transfer) or similar (General transfer) rewards. The main theories on cue-guided decision-making consider Specific transfer as driven by the activation of previously learned instrumental actions induced by cues sharing the sensory-specific properties of the reward they are associated with. However, to date, such theoretical assumption has never been directly investigated at the neural level.

A neuronal marker of eye contact spontaneously activated in neurotypical subjects but not in autistic spectrum disorders.

Attention to faces and eye contact are key behaviors for establishing social bonds in humans. In Autism Spectrum Disorders (ASD), a disturbance in neurodevelopment, impaired face processing and gaze avoidance are key clinical features for ASD diagnosis. The biological alterations underlying these impairments are not yet clearly established.

Deep brain stimulation for severe dystonia associated with Wilson disease: A prospective multicenter meta-analysis of an N-of-1 trial.

Background And Purpose: Disabling dystonia despite optimal medical treatment is common in Wilson disease (WD). No controlled study has evaluated the effect of deep brain stimulation (DBS) on dystonia related to WD. This study was undertaken to evaluate the efficacy of DBS on dystonia related to WD.

Psychiatrists' beliefs, awareness, and attitudes toward gender variance: A French cross-sectional study.

Objectives: The evolution of knowledge and recommendations concerning transgender health has led to various representations, especially for health professionals, that can influence the medical management of transgender individuals. The main objective of this study was to explore the representation of psychiatrists in France regarding gender variance. The secondary objective was to compare these data based on their characteristics.

Comparative analysis of anticholinergic burden scales to explain iatrogenic cognitive impairment in schizophrenia: results from the multicenter FACE-SZ cohort.

Aim: The anticholinergic properties of medications are associated with poorer cognitive performance in schizophrenia. Numerous scales have been developed to assess anticholinergic burden and yet, there is no consensus indicating which anticholinergic burden scale is more relevant for patients with schizophrenia. We aimed to identify valid scales for estimating the risk of iatrogenic cognitive impairment in schizophrenia.

Leo program, a short multi-family skill-based psychoeducational program for caregivers of relatives living with a severe mental disorder: a retrospective pilot study.

Background: Caring for a relative with a severe mental disorder (SMD) is associated with high levels of burden and poor physical and mental health. There is a dire need for family psychoeducational programs that can be provided as early as possible. This manuscript describes the pilot testing of "Leo" a motivational-based psychoeducational program for caregivers of individuals with a SMD.

Current and future applications of light-sheet imaging for identifying molecular and developmental processes in autism spectrum disorders.

Autism spectrum disorder (ASD) is identified by a set of neurodevelopmental divergences that typically affect the social communication domain. ASD is also characterized by heterogeneous cognitive impairments and is associated with cooccurring physical and medical conditions. As behaviors emerge as the brain matures, it is particularly essential to identify any gaps in neurodevelopmental trajectories during early perinatal life.

Adjunctive agents to antipsychotics in schizophrenia: a systematic umbrella review and recommendations for amino acids, hormonal therapies and anti-inflammatory drugs.

Question: This umbrella review and guidelines aimed to provide evidence to support the rational choice of selected adjunctive therapies for schizophrenia.

Study Selection And Analysis: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and World Federation of Societies of Biological Psychiatry (WFSBP)-grading recommendations, 63 randomised control trials (RCTs) (of which 4219 unique participants have completed the RCTs) and 29 meta-analyses were analysed.

Findings: Provisional recommendations (WFSBP-grade 1) could be made for two molecules in augmentation to antipsychotics: (1) N-acetyl-cysteine (NAC, 1200-3600 mg/day, for >12 consecutive weeks) in improving negative symptoms, general psychopathology (positive and negative syndrome scale for schizophrenia (PANSS) general psychopathology factor (G)-G subscale), with the RCTs with the longer duration showing the most robust findings; (2) polyunsaturated fatty acids (3000 mg/day of eicosapentaenoic acid, for >12 weeks) in improving general psychopathology.

Profile of patients with a positive HCV viral load in a large French psychiatric hospital (2019-2021): A case-control study.

Hepatitis C virus (HCV) is highly prevalent in people with mental disorders (PWMDs). However, in the international context of HCV elimination, no previous study has explored the features of seropositive PWMDs with vs. without a positive viral load (VL).

Risk of drug use during pregnancy: master protocol for living systematic reviews and meta-analyses performed in the metaPreg project.

Background: Knowledge about the risks of drugs during pregnancy is continuously evolving due to the frequent publication of a large number of epidemiological studies. Systematic reviews and meta-analyses therefore need to be regularly updated to reflect these advances. To improve dissemination of this updated information, we developed an initiative of real-time full-scale living meta-analyses relying on an open online dissemination platform ( www.

Motor deficits in autism differ from that of developmental coordination disorder.

A vast majority of individuals with autism spectrum disorder experience impairments in motor skills. Those are often labelled as additional developmental coordination disorder despite the lack of studies comparing both disorders. Consequently, motor skills rehabilitation programmes in autism are often not specific but rather consist in standard programmes for developmental coordination disorder.

Impairment of central language processing in critically ill coronavirus disease 2019 patients with delirium.

Accumulating evidence indicates that coronavirus disease 2019 is a major cause of delirium. Given the global dimension of the current pandemic and the fact that delirium is a strong predictor of cognitive decline for critically ill patients, this raises concerns regarding the neurological cost of coronavirus disease 2019. Currently, there is a major knowledge gap related to the covert yet potentially incapacitating higher-order cognitive impairment underpinning coronavirus disease 2019 related delirium.

An optimized iDISCO+ protocol for tissue clearing and 3D analysis of oxytocin and vasopressin cell network in the developing mouse brain.

Here, we present an optimized iDISCO+ protocol combining tissue clearing and light sheet microscopy to map the postnatal development of oxytocin and vasopressin neurons in mouse hypothalamus. We describe tissue preparation, immunostaining, clearing, and imaging. We then detail how to process the 3D cell dataset to analyze cell network using a point-based recording procedure that accurately maps neurons in the Allen brain atlas.

Caregiving-related experiences associated with depression severity and its symptomatology among caregivers of individuals with a severe mental disorder: an online cross-sectional study.

Caring for a relative with a severe mental disorder puts family caregivers to a great risk of depression. While overall caregiving burden is a strong predictor of depression, the contribution of the various dimensions of burden to caregivers' depression as well as their relationships with depressive symptoms has received little attention. 384 family caregivers completed a cross-sectional online survey including the Center for Epidemiological Studies Depression (CES-D) scale, the Zarit Burden Interview (ZBI), and the Brief Experience of Caregiving Inventory (BECI), measuring caregiving burden and experience.

Dissociation of early and late face-related processes in autism spectrum disorder and Williams syndrome.

Background: Williams syndrome (WS) and Autism Spectrum Disorders (ASD) are neurodevelopmental conditions associated with atypical but opposite face-to-face interactions patterns: WS patients overly stare at others, ASD individuals escape eye contact. Whether these behaviors result from dissociable visual processes within the occipito-temporal pathways is unknown. Using high-density electroencephalography, multivariate signal processing algorithms and a protocol designed to identify and extract evoked activities sensitive to facial cues, we investigated how WS (N = 14), ASD (N = 14) and neurotypical subjects (N = 14) decode the information content of a face stimulus.

A 1-Day Training Course to Disseminate the BREF Psychoeducational Program to Caregivers and Promote Network Establishment between Psychiatry Departments and Family Associations.

Objective: Although international guidelines state that psychoeducation to caregivers should be provided systematically, it remains insufficiently available in psychiatry. This study reports the development and evaluation of an original training course aimed to provide participants with the knowledge and skills to implement "BREF," a psychoeducational program for caregivers.

Methods: The BREF program training course, a free, 1-day course incorporating peer role-play was developed.

Culture-free perceptual invariant for trustworthiness.

Humans beings decide to trust others selectively, often based on the appearance of a face. But how do observers deal with the wide variety of facial morphologies and, in particular, those outside their own familiar cultural group? Using reverse correlation, a data-driven approach to explore how individuals create internal representations without external biases, we studied the generation of trustworthy faces by French and Chinese participants (N = 160) within and outside their own cultural group. Participants selected the most trustworthy or attractive (control condition) face from two identical European or Asian descent faces that had been modified by different noise masks.

Differential fate between oxytocin and vasopressin cells in the developing mouse brain.

Oxytocin (OXT) and arginine vasopressin (AVP), two neuropeptides involved in socio-emotional behaviors have been anatomically defined in the adult brain. Yet their spatial organization during postnatal development is not clearly defined. We built a developmental atlas using 3D imaging of cleared immunolabeled tissue over four early postnatal (P) stages, from birth (P0, P3, P7, P14) to young adulthood (≥P56).

Occurrence of Side Effects in Treatment-Resistant Depression: Role of Clinical, Socio-Demographic and Environmental Characteristics.

Treatment-resistant depression (TRD) is a disabling psychiatric condition characterized by the failure of two antidepressants (ADs). Since the occurrence of side effects (SEs) appears to be one of the main determinants of early discontinuation of pharmacological treatments contributing to a pseudo-resistance, the purpose of this study was to determine the parameters associated with the occurrence of SEs under ADs in a cohort of patients with TRD. An observational, cross-sectional, multicentre study was carried out using data from the French network of Expert Centers for TRD.

Perceptions of parents of the impact of autism spectrum disorder on their quality of life and correlates: comparison between mothers and fathers.

Purpose: To compare mothers and fathers perceptions of the impact of autism spectrum disorder on their Quality of Life (QoL), we used the Parental-Developmental Disorders-Quality of Life scale (Par-DD-QoL).

Method: The perception of QoL of mothers and fathers was compared for 130 pairs of parents of children with ASD and the associated variables were investigated.

Results: Mothers perceived a significantly greater impact of ASD on their QoL than fathers.
