Insomnia and excessive daytime sleepiness (EDS) often co-occur, despite involving distinct physiological mechanisms. The KANOPÉE application, a fully autonomous virtual agent that collects sleep-related data and delivers personalised behavioural recommendations over a 17-day period, offers a unique opportunity to better understand this unexpected phenotype. Our primary aim was to characterise these 'sleepy insomniacs', and our secondary aim was to evaluate their response to this digital sleep intervention.

Background: Lorazepam, a widely used benzodiazepine, is the first-line treatment for catatonia. In case of resistance to Lorazepam, a trial-and-error approach is usually followed, increasing the risk of severe medical complications. To date, the mechanisms underlying non-response to Lorazepam remain unclear.

The debate on whether psychiatric disorders can be studied as natural kinds has raised controversy, reviving socio-constructionist arguments about the influence of social factors on psychiatric categories. A key concept in this discussion is the "looping effect", which describes how individuals change in response to their classifications, necessitating revisions to those classifications. We argue that, until now, the broad discussions around the looping effect have greatly failed to integrate the perspectives surrounding clinicians and patients.

This study, integrated within a broader international project, aimed to assess self-reported conceptual competences among French psychiatry students and practitioners, underlining the pedagogical necessity of integrating philosophy into psychiatry education to address both clinical and research challenges.
Methods: A cross-sectional survey was conducted among French psychiatric residents, practicing psychiatrists, and retired psychiatrists recruited through professional networks and associations.

Objective: To evaluate the association between attention-deficit/hyperactivity disorder (ADHD) and atypical sensory processing patterns.
Method: For this systematic review and meta-analysis, PubMed, Embase, and Web of Science were searched from their inception until June 30, 2024. Studies examining sensory processing patterns using questionnaires in participants with a diagnosis of ADHD compared with healthy controls were included.

Circadian rhythms are near-24 h patterns of physiology and behavior associated with several physical and mental health outcomes. Self-report questionnaires are routinely used and practical tools to assess circadian rhythms. However, the extent to which these questionnaires capture the relevant parameters and can be used interchangeably is unknown.

This proof-of-concept study aims to propose a new approach to rigorously support electroclinical reasoning in the field of epilepsy.
Methods: We analyzed stereoelectroencephalographic data from 42 patients with drug-resistant focal epilepsy, whose seizures involved prefrontal cortex at seizure onset.
Computational neuropsychiatry is a leading discipline in explaining psychopathology in terms of neuronal message passing, distributed processing and belief propagation in neuronal networks. Active Inference (AI) is a way of representing this dysfunctional signal processing. According to the AI approach, all neuronal processing and action selection can be explained by maximizing Bayesian model evidence or minimizing variational free energy.

The fourth edition of the DSM (DSM-IV, 1994) introduced the clinical significance criterion (CSC) to standardize this judgment and enhance diagnostic reliability.
Methods: This review conducts a theoretical and historical content analysis of CSC presence, frequency, and formulation in the diagnostic criteria of sleep disorders.
Addiction is considered a chronic disorder that requires long-term treatment. Early identification of predictors of outcome may enable better and early adjustment of treatment. Daily fluctuations of craving have been shown to predict substance use within hours, making it a major target for treatment.

Background And Hypothesis: Deficits in early auditory processing (EAP), as indexed by tone-matching performance, have been consistently demonstrated in individuals with schizophrenia spectrum disorders. However, the ontogeny of tone-matching deficits in schizophrenia remains relatively unknown. The current study aims to determine the relationship between clinical high risk for psychosis and EAP.

This would bring together several professional organizations in their understanding of this hitherto heterogeneous concept. However, no consensus regarding a general definition of a sleep disorder currently exists.

Clinicians are recognized for their unique and irreplaceable roles. In this brief historical overview, viewed through the lens of artificial intelligence (AI), we propose that comprehending the reasoning behind AI can enhance our understanding of clinical reasoning.
View Article and Find Full Text PDFThe concept of multimorbidity in psychiatry refers to the coexistence of multiple health conditions without conceptualizing a central disorder referring to a patient-centered approach that views every diagnosis equally. It emphasizes a shift from focusing on an index disorder to considering interrelated symptoms crucial in psychiatry due to frequent multimorbidity patterns. In clinical practice, multimorbidity guides patient-centered care helping to address the holistic needs of patients and challenging the organization of mental health care.

Conceptualizing substance use as a dynamic system of causal elements could provide valuable insights into the interaction of craving with other symptoms in the process of relapse. The aim of this study was to improve the understanding of these daily life dynamic inter-relationships by applying dynamic networks analyses to EMA data sets.

One of the main goals for supporting people with a psychotic disorder is early detection and intervention, and the detection of Clinical High Risk (CHR) is a major challenge in this respect. This study sought to compare core symptoms of CHR for psychosis networks based on two CHR self-assessment tools, across different risk thresholds and age groups. This cross-sectional online investigation analyzed 936 individuals for CHR, in France and the UK, with the Prodromal Questionnaire-16 (PQ-16) and the Perceptual and Cognitive Aberrations (PCA).

Methods: This cross-sectional online study analyzed individuals from the general population to better assess their risk of symptoms classified as clinical high risk (CHR) for psychosis. The 16-item Prodromal Questionnaire was applied as a self-report screening tool.
