RESUMO
Objective To investigate brain function alteration in early onset schizophrenia by amplitude of low-frequency fluctuation (ALFF) based on resting-state functional MRI (fMRI). Method Twenty patients with early on?set schizophrenia and 20 sex, age, education years matched healthy controls underwent resting-state functional MRI. The difference in ALFF was compared between patients and controls. Result Compared with control group, the ALFF values in patient group increased in the left frontal gyrus, precuneus, cingulate cortex, occipital lobe, parahippocampal gyrus and calcarine (P<0.05, AlphaSim revised), while decreased in the right superior temporal lobe and the posterior lobe of cerebellum (P<0.05, AlphaSim revised). Conclusion There are abnormal ALFF in multiple regions in early onset schizo?phrenia, suggesting that early onset schizophrenia may have altered in resting-state brain activity.
