Key result
Schizophrenia was associated with reduced anterior prefrontal blood volume, indicated by lower hemoglobin ratios, compared to major depressive disorder and controls.
Why the study?
Prefrontal blood flow disturbances have been reported in schizophrenia and major depressive disorder, but findings regarding resting blood flow alterations have not been consistent.
Does near-infrared time-resolved spectroscopy (NIR-TRS) detect differences in anterior prefrontal resting blood volume between schizophrenia, major depressive disorder, and controls?
Cross-Sectional
Does near-infrared time-resolved spectroscopy (NIR-TRS) detect differences in anterior prefrontal resting blood volume between schizophrenia, major depressive disorder, and controls?
NIR-TRS demonstrates reduced anterior prefrontal blood volume in schizophrenia but not in major depressive disorder, suggesting utility in differentiating the two conditions.

Supports NIR-TRS differentiation of schizophrenia from MDD; hypothesis-generating and requires prospective validation before clinical use.
Shinba et al. (2022) conducted a cross-sectional in Schizophrenia and major depressive disorder. Schizophrenia vs. Major depressive disorder and healthy controls was evaluated on Anterior prefrontal hemoglobin concentration at the resting state. Schizophrenia was associated with reduced anterior prefrontal blood volume, indicated by lower hemoglobin ratios, compared to major depressive disorder and controls.
