Effect of a Multidomain Intervention Plus Turmeric on the Prevention of Cognitive Decline in People Over 55 Years of Age With Insulin Resistance: A Randomized Clinical Trial

Detailed Summary

Introduction: The Insulin resistance itself has been recognized as an independent risk factor for dementia development. Insulin plays an important role in the regulation of muscle function and the processes of learning and memory. Insulin resistance is associated with increased inflammation and oxidative stress. These processes are involved in the pathophysiology of neurodegenerative diseases. Thus, reducing IR could have implications for improving metabolism, muscle, and cognitive function. Methods and analysis. The investigators will conduct a randomized, double-blind, placebo-controlled clinical trial in which a multidomain program, including an aerobic and cognitive exercise program, will be evaluated. The latter is an exercise program conducted on a checkered mat and will be randomized to participants receiving turmeric plus black pepper or placebo. Participants are affiliated with the Mexican Social Security Institute (IMSS) and are between 55 and 74 years old. The program will last for 24 weeks; after 52 weeks, it will be repeated. The outcomes that the investigators will evaluate are: global cognitive function, specific cognitive function, and the investigators will evaluate serum markers of inflammation, oxidative stress, and GSK-3beta levels. The effect of the interventions on each variable will be analyzed by ANOVA, and a multivariate analysis study with multiple linear regression will be conducted. Ethics and dissemination of the study: the study was approved by the IMSS National Ethics and Research Committee all participants provided written informed consent prior to their participation.
