Furthermore, alterations in the subcomponents of the ASSR gamma oscillations, together with combined miR-137 and COX6A2 indices, could represent potential biomarkers of PVI impairment in early psychosis, useful for biomarker-guided treatment targeting PVIs mitochondrial impairment in specific subgroups of patients, particularly Psy-D subgroup. Here, COX6A2 is linked to psychotic disorder.
