The fMRI images of 40 SLE patients with neuropsychiatric symptoms, 40 SLE patients without neuropsychiatric symptoms and 40 healthy controls matched by sex, age and education level were collected. fMRI was selected as an evaluation method to compare the differences in brain functional changes among the three groups, and to explore the specific brain regions in the imaging of early brain injury in SLE. Neurocognitive assessment was performed on all subjects, clinical data and laboratory serum markers of SLE patients were collected, and the correlation between SLE patients and specific brain regions was analyzed, and multiple regression models were constructed to provide imaging references for early clinical diagnosis and intervention in the process of NPSLE.
