The FRS assessed in this study encompassed audible thoughts, voices arguing, voices commenting, thought insertion, thought withdrawal, thought broadcast, made feelings, made impulses, made volitions, somatic passivity, and delusional percept – these symptoms are unified by the striking breach in one’s ability ability to differentiate “self” from “non-self.” It is possible that the component of delusions and hallucinations as emphasized by the FRS might be linked with the BDNF and this might explain the heterogeneity in previous reports. Here, BDNF is linked to Delusion.
