A Bayesian Analysis of the Effect of Statins on Cognitive Impairment in Alzheimer's Patients Lead Investigator: Robert Aarhus Institution : George Mason University E-Mail : raarhus@gmu.edu Proposal ID : 299 Proposal Description: This project is aimed at acquiring an initial data set for use as part of a Bayesian analysis to explore associations between the use of statins and the rate of decline in cognition and function among Alzheimer's patients. Does a Bayesian approach detect a credible difference in the rate of cognitive decline for AD patients with/without documented hypercholesterolemia, and who are prescribed/not prescribed statins? How does rate of decline vary with age is rate of decline greater in the Early Onset population are these influenced by statins?
