Multimorbidity and vulnerability among those living with psychosis in Indigenous populations in Cape York and the Torres Strait.

Our data expose the perinatal and early environment of Indigenous children who later developed a psychotic disorder. As risk factors for schizophrenia may be cumulative and interactive, both with each other and with critical periods of neurodevelopmental vulnerability, our results suggest possible causes for the increasing prevalence of psychotic disorders between 1992 and 2015.
