Abstract

Objective. To systematically assess the safety and efficacy of olanzapine versus clozapine when treating senile dementia and to provide evidence-based medicine basis for its promotion and use. Methods. PubMed, Embase, ScienceDirect, Cochrane Library, China Knowledge Network Database (CNKI), China VIP Database, Wanfang Database, and China Biomedical Literature Database (CBM) online database were searched for randomized controlled trials (RCT) of olanzapine and clozapine when treating senile dementia. The retrieval time limit is from the establishment of the database to the present. The data were extracted independently by two researchers, and the bias risk of each contained literature was analyzed in accordance with the standard of Cochrane Handbook 5.3. RevMan 5.4 statistical software was used to analyze the collected data by meta-analysis. Results. Finally, 6 randomized controlled trial articles were included, with a total of 490 samples. Meta-analysis of clinical efficacy showed that the clinical efficacy was similar and there was no significant difference ( P > 0.05 ). Two articles used Alzheimer’s disease pathological behavior rating scale (BEHAVE-AD) to compare the pathological behavior of different stages after treatment. Statistical analysis showed that there was no significant difference between the total score of BEHAVE-AD and the scores of each factor in each week after treatment. The non-treatment adverse reaction scale (TESS) of the study group and the control group was analyzed by meta-analysis. The TESS score of the study group after treatment was significantly lower than that of the control group. The BPRS scores of different stages after treatment were analyzed by meta-analysis, and there was no significant difference in the total score and factor scores of BPRS in each week after treatment. Two clinical trials reported the incidence of neurological symptoms after treatment. Olanzapine and clozapine treatment can effectively reduce the risk of aging. There was no significant difference in the incidence of neurological symptoms in patients with dementia ( P > 0.05 ). According to the analysis of meat products, the incidence of adverse reactions in the study group was significantly lower than that in the control group ( P < 0.05 ). Conclusion. Olanzapine and clozapine have similar efficacy when treating mental and behavioral disorders in patients with senile dementia, in which olanzapine is more effective in improving the symptoms of patients with Alzheimer’s disease (AD), with less adverse reactions and high safety, which is worth popularizing in clinical practice. However, more studies and follow-up with higher methodological quality and longer intervention time are needed to further verify.
