A symptom-based approach to treatment of psychosis in autism spectrum disorder in October 2017.

The optimal management of autism with psychosis remains unclear. This report describes a 22-year-old man with autism and psychosis who was referred to a tertiary-level specialist psychosis service, following a 6-year history of deterioration in mental health starting around the time of sitting GCSE examinations and an episode of bullying at school. We describe the individualised symptom-based approach that was effective in his treatment. Declaration of interest The authors declare no conflict of interest.
