The prevalence of inflammation defined as CRP > 3 mg/L was 32% for psychotic disorders (ICD F 20–29), 21% for mood disorders (F30–39), 22% for neurotic disorders (F 40–48), and 42% for personality disorders (F60–69), indicating that low grade inflammation could be present in a whole range of psychiatric disorders (21). This evidence concerns the gene CRP and psychotic disorder.
