Autistic features are commonly observed in children and adolescents with first-episode psychosis, but they are sometimes overlooked by clinicians and caregivers. By comprehensively examining the clinical profiles of 103 children and adolescents (below 18 years old) with first-episode psychosis and conducting the Autism Diagnostic Interview-Revised (the 'gold standard' autism diagnostic tool) with their primary caregivers, we showed that around 28% of patients with first-episode psychosis had a comorbid autism diagnosis, and boys were 3.57 times more likely to have first-episode psychosis-autism spectrum disorder comorbidity than girls. After administering the Autism Diagnostic Interview-Revised, we also observed that an additional 30% of patients with first-episode psychosis met the autism spectrum disorder diagnostic cut-off; their autism spectrum disorder symptoms were probably overshadowed by prodromal psychotic symptoms and left undetected before this study. The co-occurrence of autism and first-episode psychosis might be more common than we previously thought. Careful autism screening and assessment is highly recommended for clinicians working with patients with psychosis.

Disrupted gamma-aminobutyric acid (GABA) neurotransmission may contribute to the pathophysiology of schizophrenia. Reductions in hippocampal GABAergic neurons have been found in schizophrenia, and increased hippocampal perfusion has been described in schizophrenia and in people at clinical high-risk for psychosis (CHRp). We have also found decreases in hippocampal GABA receptors containing the α5 subunit (GABARα5) in a well-validated neurodevelopmental rat model of relevance for schizophrenia.

Iron-the most abundant magnetic brain substance-is essential for many biological processes, including dopamine and myelin synthesis. Quantitative susceptibility mapping (QSM) MRI has recently linked altered subcortical magnetic susceptibility (χ) to schizophrenia. Since χ is increased by iron and decreased by myelin, abnormal levels of either could underlie these QSM differences.

Background: Psychological therapy (PT) along with antipsychotic medication is the recommended first line of treatment for first-episode psychosis (FEP). We investigated whether ethnicity, clinical, pathways to care (PtC) characteristics, and access to early intervention service (EIS) influenced the offer, uptake, and type of PT in an FEP sample.
Methods: We used data from the Clinical Record Interactive Search-First Episode Psychosis study.

While associations between duration of untreated psychosis (DUP) and outcome are robust and have been influential in early intervention, whether similar associations and potential utility exist for the preceding duration of the psychosis prodrome (DPP) remain to be clarified. This study investigated prospectively across seven years: (i) whether DPP is associated with outcome; (ii) whether any prediction by DPP varies across long-term follow-up after initiating treatment; and (iii) whether these relationships vary across gradations of DPP values. Sixty subjects were evaluated for DPP at first episode psychosis (FEP) and for psychopathology and quality of life at both FEP and 7-year follow-up; functionality and service engagement were assessed at follow-up.
