Non-steroidal Anti-Inflammatory Drugs as protective Factor in Alzheimer's Diseases: a Systematic Review and Meta-Analysis Protocol (Preprint)

Introduction: NSAIDs inhibit COX-2, which is responsible for regulating neurons leading to neurodegeneration in Alzheimer’s disease. Alzheimer’s disease is a neurodegenerative disease affecting the geriatric population, as it affects more than two third cases of dementia in the sphere. Results obtained from experimental and observational studies were unclear regarding the protective role of NSAIDs in AD, therefore this justifies the need for meta-analysis. Methods: Database search was PubMed, Web of Science, and Embase. Experimental studies and Observational studies investigating the effect of NSAIDs on AD. For experimental studies indicators used were MMSE score, ADAS-cog score, CDR-sob score, NPI score, and Hazard ratio. Similarly for Observational studies, Odds Ratio and Relative Risk are used. Results: As this is the study protocol, therefore it is not possible to write the results of the study in the study protocol. There is a total of 06 (MMSE, ADAS-cog, CDR-sob, HR, RR, and OR) indicators used in the study, so 06 results will be obtained showing the pooled effect size which will indicate the use of NSAIDs as a protective factor for Alzheimer’s disease. Discussion: The present systematic review will improve the understanding of the relative efficacies of NSAIDs in AD and possibly guide clinical practices by providing the current best evidence on the efficacy of various regimens of NSAIDs in the management of AD subjects. Conclusion: Conclusion can be drawn only after the final meta-analysis using three study design (RCT, Cohort and Case-control study designs) and six indicators.
