Schizophrenia patients often present with changes in circulating immune proteins, which can cross the blood-brain barrier (BBB) and directly affect brain function. Many studies have hypothesized that psychosis is related to a dysregulation in the peripheral immune system that leads to abnormal signaling in the BBB. Patients defined as high-risk are 100 times more likely to develop a psychotic disorder within 2 years of diagnosis, and being able to predict progression to psychosis can be a useful tool for early intervention and improve clinical outcomes.
