Cannabis use in adolescence and risk for adult psychosis: longitudinal prospective study
TLDR
This is the first prospective longitudinal study of adolescent cannabis use as a risk factor for adult schizophreniform disorder, taking into account childhood psychotic symptoms, and the Dunedin multidisciplinary health and development study has a 96% follow up rate at age 26. Expand
Children's self-reported psychotic symptoms and adult schizophreniform disorder: a 15-year longitudinal study.
TLDR
These findings provide the first evidence for continuity of psychotic symptoms from childhood to adulthood, and the link between child and adult psychotic symptoms was not the result of general childhood psychopathology. Expand
Obstetric complications and schizophrenia: historical and meta-analytic review.
TLDR
Current methods of investigating the relationship between obstetric complications and schizophrenia are reaching the limit of their usefulness, and a combination of disciplines and approaches will be needed to elucidate the mechanisms underlying these small but important associations. Expand
Prevalence of psychotic symptoms in childhood and adolescence: a systematic review and meta-analysis of population-based studies
TLDR
A systematic review of all published literature on psychotic symptom prevalence in two age groups, children aged 9–12 years and adolescents aged 13–18 years, searching through electronic databases PubMed, Ovid Medline, PsycINFO and EMBASE up to June 2011 and extracted prevalence rates. Expand
Prevalence and correlates of self-reported psychotic symptoms in the British population
TLDR
Self-reported psychotic symptoms are less common in this study than reported elsewhere, because of the measure used, but these symptoms have demographic and clinical correlates similar to clinical psychosis. Expand
Moderation of the Effect of Adolescent-Onset Cannabis Use on Adult Psychosis by a Functional Polymorphism in the Catechol-O-Methyltransferase Gene: Longitudinal Evidence of a Gene X Environment
TLDR
Findings provide evidence of a gene x environment interaction and suggest that a role of some susceptibility genes is to influence vulnerability to environmental pathogens. Expand
Evidence for early-childhood, pan-developmental impairment specific to schizophreniform disorder: results from a longitudinal birth cohort.
TLDR
Evidence is provided for an early-childhood, persistent, pan-developmental impairment that is specifically associated with schizophreniform disorder and that predicts psychotic symptoms in childhood and adulthood. Expand
Clinicopathological significance of psychotic experiences in non-psychotic young people: evidence from four population-based studies
TLDR
Investigating the relationship between psychotic symptoms and non-psychotic psychopathology in community samples of adolescents in terms of prevalence, co-occurring disorders, comorbid (multiple) psychopathology and variation across early v. middle adolescence found psychotic symptoms are important risk markers for a wide range of non- Psychotic psychopathological disorders. Expand
Childhood trauma and children's emerging psychotic symptoms: A genetically sensitive longitudinal cohort study.
TLDR
Trauma characterized by intention to harm is associated with children's reports of psychotic symptoms and Clinicians working with children who report early symptoms of psychosis should inquire about traumatic events such as maltreatment and bullying. Expand
Childhood trauma and psychosis in a prospective cohort study: cause, effect, and directionality.
TLDR
The authors found that exposure to childhood trauma predicted newly incident psychotic experiences, and provides the first direct evidence that cessation of traumatic experiences leads to a reduced incidence of psychotic experiences. Expand
