Summary of the Proposed Research:

Alzheimer’s disease (AD) manifests with strikingly different ages and sites of onset, progresses at different rates and in different anatomic directions, and has varied responses to treatment 1. Disease-modifying AD clinical trials have been disappointing; however, detailed analyses often show a subset of patients with improved outcomes 2–5. We hypothesize that AD is heterogeneous and only subsets of patients may respond to each treatment. Using computational analysis, we propose to identify biomarkers that correlate with the four critical clinical variables (age and site of onset, rate and direction of progression) and to test whether those markers correlate with responses to AD medications. The results of our analysis could provide unparalleled insights into whether a subject would respond, or not, to an investigational medication and whether a subject is likely to have rapid disease progression. It could also inform the basis of inclusion criteria for future clinical trials, ultimately increasing the likelihood of a positive outcome for both the investigational medication and the research subjects.
