The Promise of Predictive Biomarkers for Antipsychotic Efficacy: A Review of Peripheral microRNAs to Evaluate Schizophrenia Treatment Response

With the ongoing evolution in genetics, recent evidence highlights the role of circulatory microRNA (miRNA) for schizophrenia. The objective of this article is to explore the role of blood/serum miRNA expression in schizophrenia management and to review the expression of different miRNAs before and after treatment with antipsychotics. miRNAs can help increase the accuracy of diagnosis, identify patients at risk of developing schizophrenia, and possibly predict drug response. The collective evidence from this review showed that several miRNAs are promising candidates for schizophrenia diagnosis, management, and prognosis.
