Altered neuroaxonal integrity in schizophrenia and major depressive disorder assessed with neurofilament light chain in serum.

J Psychiatr Res 2021 Jun 2;140:141-148. Epub 2021 Jun 2.

Department of Psychiatry, Psychotherapy and Psychosomatics, Psychiatric University Hospital Zürich, University of Zurich, Switzerland; Neuroscience Center Zurich, University of Zurich and Swiss Federal Institute of Technology Zurich, Zurich, Switzerland.
