Psychiatric disorders and development

The Department of Child and Adolescent Psychiatry of the Pitié-Salpêtrière hospital group conducts research whose themes are closely linked to the psychiatric disorders that are treated in the department. There are two primary areas of research: childhood developmental disorders and severe psychiatric disorders in adolescents, both with a view to understanding the etiological factors, studying their clinical heterogeneity, and establishing approaches to therapeutic management. Three types of studies are conducted : in clinical research; in the field of genetics and proteomics of psychiatric disorders; in the field of cognitive psychology and engineering.

Our clinical research group (GRC) is pursuing three main lines of research in three teams:

Team 1: led by C. Laurent-Levinson, MCU-PH (Maître de Conférences des Universités-Praticien Hospitalier). This project is a continuation of previous work and concerns the “Dimensional approach of psychotic episodes in children and adolescents: genetic, metabolic and autoimmune implications“. This study of the clinical characterization of neurodevelopmental dimensional profiles of early-onset schizophrenia is being expanded with a multi-center national recruitment effort (PHRC interregional funding) and with a multidisciplinary approach including assessment of clinical / developmental / pharmacological (response to treatment) profiles, and functional imaging, cognitive and neuropsychological assessment. We will continue to identify genetic abnormalities and will contribute to the characterization of the phenotypes of children / adolescents with psychotic disorders who carry these CNVs and of children with multiple neurodevelopmental disorders (ASD, ADHD, learning disabilities, social communication disorders)

The second line of research led by A. Consoli, PU-PH (Professeur des Universités – Praticien Hospitalier), concerns clinical and therapeutic aspects of rare, severe and complex syndromes of development. Clinical research is aimed at establishing correlations between therapeutic responses and clinical and etiological dimensions (children and adolescents with the same genetic defect, the same autoimmune context). Thus, in collaboration with the the Center of Rare Diseases with Psychiatric Expression (Centre de maladies rares à expression psychiatrique, CRMR), we have a particular interest in the efficacy of topiramate on irritability / impulsivity symptoms, hyperphagia, self-mutilation in Prader Willi syndrome (currently conducting an 8-week randomized double-blind multi-center study). A second area of interest is the characterization of early forms of bipolar type I disorder. Previously, we conducted a study of adolescent-onset cases of bipolar disorder type I. We are currently developing a project to characterize Disruptive mood dysregulation disorder (DMDD) in pre-pubertal children. Finally, we are conducting research on catatonic syndrome associated with organic (including auto-immune) pathologies, and we are continuing the study of our cohort of children and adolescents with catatonia (clinical, ethio-pathogenic, genetic and therapeutic).

Team 3 led by David Cohen, PU-PH (Professeur des Universités – Praticien Hospitalier), this team focuses on cognition and social interactions. The objectives of this group are simultaneously fundamental (testing of certain theoretical models of the interactions of the cognitive and emotional functioning) and applied (studies of evaluation and of clinical management) using robotics as a tool. The fundamental aspects are developed at the ISIR (engineering laboratory) while the GRC team carries out the clinical evaluation and management protocols. This original psychopathological approach is currently exploring some hypotheses of early infant mother interactions, neurodevelopmental disorders, and stress management.
