Abstract

Objective

·To explore the effects of computerized cognitive correction therapy (CCRT) on the cognitive function of patients with chronic schizophrenia and the effects on plasma brain-derived nerve growth factor (BDNF) and tyrosine kinase receptors B (TrK-B) .

Methods

·162 patients with chronic schizophrenia from Shanghai Mental Health Center of Huangpu District were randomly divided into CCRT group and control group according to the random number table method. 81 patients in the control group were treated with the conventional antipsychotic drugs, and 81 patients in the CCRT group were given CCRT combined with the conventional antipsychotic treatment. The period of treatments is 12 weeks. The cognitive function by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), detection of plasma BDNF and TrK-B expression levels by avidinbiotincomplex-Enzyme Linked Immune Sorbent Assay (ABC-ELISA) were assessed at the baseline and at the end of the 12th week. Paired sample t-test was applied to compare the cognitive function, plasma BDNF and TrK-B protein expression levels in the baseline between the two groups, and the repeated measurements variance analysis was used to compare the cognitive function and plasma BDNF and TrK-B protein expression levels between the two groups after treatment and change within the group. The correlation between the improvement of cognitive function and the change of protein expression levels used a general linear model.

Results

·The CCRT group and the control group actually completed 77 cases each. At the baseline, there was no statistically significant difference among cognitive function, BDNF and TrK-B between the two groups; after 12 weeks of treatment, cognitive function (P=0.000), BDNF (P=0.007) and TrK-B (P=0.015) expression level was statistically different between the CCRT and the control group; for CCRT group, cognitive function (P=0.000), BDNF (P=0.002) and TrK-B (P=0.000) expression level was significantly different after 12 weeks of treatment compared with the baseline, but not in the control group. The change of BDNF protein expression level is significantly correlated with the improvement of vocabulary learning (r2=1.598, P=0.019), story retelling (r2=1.495, P=0.038), digital breadth (r2=1.855, P=0.004), story recall (r2=1.459, P=0.047) and attention function (r2=1.673,P=0.012). The change of TrK-B protein expression level is significantly correlated with the improvement of picture naming (r2=1.582, P=0.034).

Conclusion

·The use of CCRT in the adjuvant treatment of antipsychotic treatment for schizophrenia patients has a significant effect on cognitive function. The improvement of some cognitive functions are significantly related to the changes in the plasma BDNF and its TrK-B expression levels.
