Abstract
- The study focused on the predictive value of baseline metabolite ratios in bilateral hippocampus of first-episode schizophrenia by using proton magnetic resonance spectroscopy ( 1 H MRS). 1 H MRS data were acquired from 23 hallucination and 17 non-hallucination first-episode schizophrenia patients compared with 17 healthy participants. Clinical characteristics of patients were rated using the Positive and Negative Syndrome Scale (PANSS) before and after 3-month treatment. The schizophrenia patients showed lower NAA/Cr ratio than healthy participants respectively ( p = 0.024; p = 0.001), and non-hallucination patients had even lower NAA/Cr ratio than hallucination patients ( p = 0.033). After 3-month treatment, hallucination patients had greater improvement in negative symptoms than non-hallucination patients ( p = 0.018). The reduction of PANSS total score and negative factor score was positively correlated with the left NAA/Cr in both group patients ( p < 0.05). Given that the bilateral hippocampal baseline NAA/Cr had predictive value for the whole treatment response, and the left hippocampal NAA/Cr can predict the prognosis of negative symptoms during acute phase medication in first-episode schizophrenia.
