NCT06045897
The goal of this observational study is to compare subjects with at-risk-mental-state, early psychosis, schizophrenia, depression, and autism spectrum disorders, with healthy controls (N = 21 x 6). The main questions it aims to answer are: * are EEG microstate anomalies associated with diagnosis, clinical and functional prognosis, both in resting conditions and during sleep ? * are EEG microstates anomalies associated with differences in sensorimotor integration, prosodic and conversational, interoceptive, and narrative self ? * an ancillary study will be to see whether in healthy controls EEG microstate properties vary under light hypnosis conditions. Participants will: * undergo deep phenotyping based on psychopathology and neuropsychological assessments * undergo a high-resolution EEG (64 electrodes) with a resting period and a sensorimotor task; and healthy controls will have a light hypnosis period. * undergo a recording of the characteristics of their voice (tone, prosody) * undergo a one-night polysomnography * undergo MRI and biological sampling for multi-omic analyses * undergo a virtual reality experience
NCT06040944
The aim of the present cohort retrospective study is to explore the effect of antipsychotics on periodontal health and the possible effect of antipsychotic-induced hyperprolactinemia as a risk factor for periodontal disease progression in schizophrenic patients. The study population consisted of three groups: Group A (n = 21): schizophrenic patients who have been taking "prolactin inducing" antipsychotics for at least 1 year, Group B (n = 21): schizophrenic patients who have been taking "prolactin sparing" antipsychotics for at least 1 year and Group C (n = 22): newly diagnosed schizophrenic patients and/or patients who did not receive any psychiatric treatment for at least 1 year. The study groups underwent an assessment of periodontal condition in terms of pocket depth (PD), clinical attachment loss (CAL), gingival recession, tooth mobility, and bleeding on probing (BOP). Also, bone mineral density was evaluated using DEXA scans and the serum prolactin level was measured by automated immunoassay.
