Abstract:

Objective To explore the effect of electroencephalography mental activity evaluation system applied to the mental evaluation of the patients with brain injury. Methods A total of 52 inpatients with brain injury were evaluated with 10 indexes of anxiety depression status and electroencephalography mental activity status by psychological professionals. The Spearman correlation index from SPSS 13.0 was used to analyze the correlations between each 10 indexes of electroencephalography mental activity status and the anxiety depression emotion of the 52 patients with brain injury. Results There were significant differences between various anxiety levels and the global index of electroencephalography mental evaluation (χ 2=21.843, P =0.009), and the levels of anxiety status were in significantly negative correlation with the global index of electroencephalography mental evaluation (R =-0.311, P =0.025). There weren’t significant differences between various depression levels and the global index of electroencephalography mental evaluation (χ 2=6.622, P =0.676), neither had statistic correlation (R =0.143, P =0.310). The anxiety status level was in significantly positive correlation with the energy consumption of brain (R =0.397, P< 0.001), brain fatigue (R =0.239, P =0.004). The depression status level was in significantly positive correlated with the energy consumption of brain (R =0.239, P =0.004), brain fatigue (R =0.173, P =0.039), inner focus (R =0.187, P =0.025) and brain fatigue (R =0.220, P =0.008) from the electroencephalography mental

evaluation of the patients with brain injury; also was in significantly negative correlation with the outer focus (R =-0.165, P =0.039) from the electroencephalography mental evaluation of the patients with brain injury. Conclusion Some of the indexes of electroencephalography mental activity evaluation system could reflect the change of anxiety and depression emotional status of the patients with brain injury. The electroencephalography mental activity evaluation system could assist to evaluate the emotional status of the patients with brain injury who have speech and cognitive functional disorders.
