    Targeted and Non-Targeted Metabolomic Evaluation of Cerebrospinal Fluid in Early Phase Schizophrenia: A Pilot Study from the Hopkins First Episode Psychosis Project by George E. Jaskiw, Mark E. Obrenovich, Curtis J. Donskey, Farren B. S. Briggs, Sun Sunnie Chung, Anastasiya I. Kalinina, Austin Bolomey, Lindsay N. Hayes, Kun Yang, Robert H. Yolken, Akira Sawa

    Published 2025-04-01
    “…Compared to peripheral compartments, cerebrospinal fluid (CSF) more closely reflects the chemical composition of brain extracellular fluid. Given that brain dysregulation may be more pronounced during the first episode of psychosis (FEP), we hypothesized that metabolomic analysis of CSF from FEP patients could reveal disease-associated biomarkers. (2) Methods: We recruited 15 patients within 24 months of psychosis onset (DSM-4 criteria) and 14 control participants through the Johns Hopkins Schizophrenia Center. …”
