The post examines the theory of treating schizophrenia's prodrome stage, exploring how early intervention might prevent full-blown schizophrenia and discussing the biological mechanisms behind the disease's progression. Longer summary

This post discusses the concept of treating the prodrome of schizophrenia, an early stage where symptoms are just beginning to develop. The author explores the theory that early intervention can prevent full-blown schizophrenia, comparing it to early detection in other medical conditions. The post delves into the 'Duration of Untreated Psychosis' (DUP) model, which suggests that psychosis can be toxic to the brain. The author initially expresses skepticism about this model but later becomes more open to it after learning about the biology of schizophrenia. The post then explains a theory of how schizophrenia develops through aberrant prediction errors and how this process might lead to both positive and negative symptoms. It concludes with a first-person account of schizophrenia that illustrates these concepts. Shorter summary
