RESUMEN
Objective:To evaluate the changes of neurocognitive function in early stage in patients with first-episode schizophrenia.Methods:In this study,73 cases of patients with first-episode schizophrenia (research group) and 75 cases of health person (control group) were selected from January 2015 to January 2016 in our hospital.The neurocognitive function was evaluated by neuro-psychological testing tool and the data between two group were compared.Results:Scores of delayed recall,total recall,3 trial,2 trial and 1 trial of research group were lower than those of control group in BVMT-R test,and the difference was statistically significant (P＜0.05).In HVLT-R test,the scores of total delay,3 trial and 2 trial of research group were significantly lower than those of control group (P＜0.05).The consuming time of dominant hands and subdominant hands in pegboard tasks were significantly higher in research group than in control group (P＜0.05).Conpletion time of connection test A,color connection 1 and 2 in connection test of research group were significantly higher than those of control group (P＜0.05).Attempt number and correct number in research group in PASAT test were significantly lower than in control group (P＜0.05).Number of search errors in research group was higher than in control group,while number of search correct,search total score and digital sign score were significantly lower than in control group (P＜0.05).Total number of words,color and color / word count in research group were lower than in control group in Stroop color word test,and the difference was statistically significant (P＜0.05).WMS-Ⅲ test results between two group had no significant difference (P＞0.05).Conclusion:The neurocognitive function in early stage in patients with first-episode schizophrenia has been extensively damaged.
