Gray Matter Iron and Neuromelanin in Psychosis: A Systematic Review and Meta-Analysis of MRI Studies

What is it about?

This review analysed all previous studies using magnetic resonance imaging (MRI) to examine brain iron and neuromelanin, a marker of dopamine function, in psychosis. Lower brain iron and higher neuromelanin were observed in psychosis, suggesting that iron metabolism and neuromelanin may represent potential targets for further investigation.
