The cognitive decline associated with healthy aging begins in early adulthood and is important to understand as a precursor of and relative to mild cognitive impairment and Alzheimer disease. Anatomical atrophy, functional compensation, and network reorganization have been observed in populations of older adults. In the current study, we examine functional network correlates of memory performance on the Wechsler Memory Scale IV and the Mnemonic Discrimination Task (MST). We report a lack of association between global graph theory metrics and age or memory performance. In addition, we observed a positive association between lure discrimination scores from the MST and right …

Theses and Dissertations
Individuals who speak more than one language have been found to enjoy a number of benefits not directly associated with the use of the languages themselves. One of these benefits is that bilingual individuals appear to develop symptoms of dementia 4-5 years later than comparable individuals who speak just one language. Studies on this topic, however, do not consistently account for factors including if the individual learned their second language as a child or later in life, or their language proficiency. In an attempt to more carefully examine these variables, this study looks at structural and resting-state functional MRI scans …
