Electronic Thesis and Dissertation Repository
Major depressive disorder (MDD) is a highly debilitating neuropsychiatric illness which has been linked with increases in both peripheral and central inflammation, as well as with changes in connectivity. Although countless studies have investigated these two topics, the relationship between neuroinflammation and functional/structural connectivity has not been explored. Using [18F]FEPPA PET imaging, we measured translocator protein-related (TSPO) microglial activity in the subgenual anterior cingulate cortex (sgACC) and insula and confirmed significantly increased [18F]FEPPA uptake in depressed patients (N=12) compared to healthy controls (N=23). Using a seed-based ROI analysis of fMRI data, we found that patients show …

Shift work schedules are designed to maintain a continuous operation of goods and services. However, engaging in shift work may impact cognitive functioning. This thesis assessed the relationship between shift work and cognitive performance. Using cross-sectional data from the Canadian Longitudinal Study on Aging, multiple linear regression models were used to investigate the association between shift work and cognitive performance, as well as the moderating effects of psychological distress and sleep quality. Differences by sex and retirement status were also investigated. Shift work was significantly associated with poor performance for executive functioning but not for declarative memory. Poorer cognitive performance …
