Proposed Analysis: The primary objective is to explore candidate functional imaging biomarkers, namely the Network Failure Quotient and its constituent elements, for significant differences among groups of cognitively normal and MCI ADNI 2 study participants cognitively categorized via two different methods. Thus, group-level differences in the functional imaging biomarkers of interest will be analyzed in a single cohort of patients under two different approaches to cognitive classification. The first method is that specified within the ADNI 2 study Procedures Manual. The alternative approach, developed by Edmonds, et. al., classifies subjects through a cluster analysis based on alternative comprehensive neuropsychological test data. The secondary objective is to ascertain a reliable threshold value for the NFQ and/or any significant constituent elements to differentiate cognitively normal from cognitively impaired individuals within the MCI/AD spectrum. Through this study, I hope to build upon advances in our understanding of functional imaging biomarkers and methods of cognitive classification within the context of MCI/AD.
