[Correlation of cognitive function with intracranial lesions and the degree of depression and anxiety in patients with neuromyelitis optica spectrum disorders].

To investigate the correlation of cognitive dysfunction with intracranial lesions and symptoms of depression and anxiety in patients with neuromyelitis optica spectrum disorders (NMOSD). Thirty-one NMOSD patients (7/24 males/females) were enrolled in the Department of Neurology of the Sixth Medical Center of the PLA General Hospital from August 2019 to August 2022. The average age was 42±13 years, and the average education level was 12 (9, 12) years. There were 30 healthy controls, 11/19 males/females, with an average age of 47±9 years and an average education of 12 (9, 15) years. The general clinical data and imaging data were collected, and the subjects were assessed on their cognition, anxiety and depression using the assessment scale approved at home and abroad. A cross-sectional study was conducted on them. The -test or Wilcoxon test was used for inter-group comparison, and Pearson test or Spearman test was used to explore the correlation between the cognition of NMOSD patients and their intracranial lesions, depression and anxiety. Compared with the healthy control group, NMOSD patients had significantly lower scores on MoCA (=-3.10,=0.002), CRAVLT-N7 (=-5.12, <0.001), CRAVLT-N8 (=-4.40, <0.001), ROCF-R (=-3.10,<0.01), ROCF-C (=-2.72,<0.01), PASAT-3 (=-2.71,<0.01), PASAT-2 (=-3.14,<0.01), and CWT-A (=-3.10,<0.01)scales. Frontal lobe lesions were negatively correlated with PASAT-2 (=-0.448, =0.012) scores, temporal lobe lesions were negatively correlated with CRAVLT-N9 (=-0.564, =0.001), and parietal lobe lesions were negatively correlated with MoCA (=-0.374, =0.038), PASAT-3 (=-0.426, =0.017), and PASAT-2 (=-0.459, =0.009) scores; The scores of MoCA (=-0.392, =0.029), CRAVLT-N6 (=-0.396, =0.028), CRAVLT-N7 (=-0.415, =0.020), CRAVLT-N8 (=-0.406, =0.023), PASAT-3 (=-0.537, =0.002) and PASAT-2 (=-0.495, =0.005) scales were negatively correlated with the scores of HAMD assessment, and the scores of PASAT-3 (=-0.499, =0.004) and PASAT-2 (=-0.452, =0.011) were negatively correlated with the scores of HAMA. The cognitive function of patients with NMOSD is significantly reduced, involving multiple cognitive domains. The cognitive function is affected by the distribution of intracranial lesions and the degree of depression and anxiety.
