The traumagenic neurodevelopment model of psychosis, introduced in 2001, highlighted similarities between brain abnormalities found both in people who have been abused and those who are diagnosed with schizophrenia – at the time a radical shift in thinking. This article in Neuropsychiatry by John Read, Roar Fosse, Andrew Moskowitz, and Bruce Perry reviews the research findings since then, and finds that both direct and indirect support for the model has grown.
